Has your child gotten a flu vaccine yet? Which one?

Let’s see which vaccine kids are getting and why.

Hi all – it’s September, which is the unofficial start of flu vaccine season!

Since this year we have flu vaccine choices again (shot or nasal spray), and different recommendations from different organizations (i.e. CDC and AAP), I wanted to survey people to see what their docs recommend and what their child(ren) receive.  With FluMist (nasal spray influenza vaccine) back on the scene but no data on its effectiveness until December 2018 at the earliest, this will be an interesting flu season.

Please use the comments box below to let us know.  I will tally results every week or so and post here, so check back for updates.

Remember, it is very important to have your child vaccinated, whichever method you choose.  Earlier is better, so just do it!

Also, if you are pregnant, please get a flu vaccine ASAP (although I’m sure your obstetrician or nurse midwife is already on top of this).  Also any partners or others who will be spending significant time with your baby (i.e. grandparents) should receive one as well.

 

HPV Vaccine (updated 10-9-2018)

Gardasil

Today is HPV vaccine day!!  (I just decided it.)

I’m hoping to get to most of the vaccines commonly used in Pediatrics over time, but HPV vaccine is both an important and timely place to start.

Human papilloma virus is a scourge.  Previously felt to be only the cause of genital warts, it is now known to also cause the majority of cases of cervical cancer, most anal and penile cancers, and a large number of head and neck cancers.

Although treatments for HPV infection are only fairly effective, since 2006 we have had a licensed vaccine to prevent the most dangerous strains of HPV.  Initially, the vaccine covered either 2 or 4 strains of HPV.  In the past few years the vaccine has been improved and now prevents the 9 most commonly cancer-causing strains of HPV.

The basics:

-HPV vaccine, called Gardasil, which stands for “guard against squamous intraepithelial lesion”, the official designation of cervical precancer (yes, I know, terrible name – all drugmakers seem to have no talent for naming their products) is approved to use from ages 9-45 years old.

-Most doctors start giving it at age 11.

-If started at age 14 years or younger, a patient needs only 2 doses, at least 6 months apart.

-If started at age 15 or older one needs 3 doses, with at least 1 months  between the first 2 doses and with #3 given at least 6 months after #1.

-The vaccine is very safe and very effective.

-There is no link between getting HPV vaccine and initiating sexual activity, just like there is no link between getting a tetanus shot and playing with rusty nails.

Bottom line (literally): HPV vaccine is cancer prevention.

HPV vaccine has probably caused more discussion and controversy than any other vaccine after the MMR vaccine.  It seems to be inextricably tied up in an emotional battleground, with a lot of people scared both of the vaccine and of what its use means to them – the fact that their child will likely be intimate with other people in the future.  Whether parents who resist this vaccine do it on the basis of what they have read on the scaremonger websites, or whether they feel it goes against their religious beliefs to use it, or whether they just plain don’t want to think about this, our results in protecting our children from HPV are pretty dismal: only about 55% of boys and 65% of girls from 13-17 years old had received even a single dose.  This is FAR below every other routine pediatric vaccination used in the U.S.

The really painful part of this awful statistic is that HPV it not a disease of the young and  promiscuous; it takes women when they are in their 40s and 50s; when they may be wives, mothers, or grandmothers.  For those unlucky enough to develop cancers of the head and neck, many people need disfiguring surgery or worse.

Hepatitis B, which is also mainly spread by intimate contact, is also prevented by a highly effective vaccine.  This vaccine is given during infancy and has much better vaccination rates, with very little argument over its importance.  This is due in large part to the “Hep B message” being about preventing chronic liver disease and liver cancer, while the “HPV message” seems stuck on sex.


For my own patients and their parents: this is the part I told you about!!

In discussions in my office, I find that a lot of parents fall into 2 categories: those that know a lot about the HPV vaccine and want their child to get it, and those who are sure they do not want their child to get it before I even mention it.  Many of the second group are already dug in, but I’m wondering if we would have a different conversation if their child was not present, or if we had emailed about the issue prior to the appointment.  I say this because it seems that what many of these parents really don’t want is to be talking about their child and sex, especially in front of their 10- or 11-year old child.  I’m thinking that if this conversation came up in a coffee shop, not when we are all painfully pressed for time, the discussion might go a different way.   In the end, I think getting the HPV vaccine is REALLY important for your kids, of BOTH genders, and at the right age, not just “maybe next year”.  I don’t get anything out of your child’s vaccination except knowing that he or she is protected against a cancer that can be debilitating or worse.  Doctors do not get paid for giving vaccines, and we don’t collude with vaccine manufacturers to make sure they sell a lot of their products.

Now, I’m not suggesting that we all need to do a pre-physical-exam prep session at Starbucks, but in the end what a lot of people need most is information, delivered in a low-stress setting, with plenty of time for give and take.  I also happen to be a big fan of Starbucks and would love to have a session with a group of parents outside the office some time.  Any takers????


June 18, 2018: for more perspective on the marketing of vaccines, see this article from the medical/science/tech site STAT on the new, hipper approach that Gardasil’s maker (Merck) is using in its direct to consumer ads:

August 2018: a new CDC report indicates that by age 13-15 years, only half of U.S. teens have received the full series of HPV vaccines (either 2 or 3 doses, depending on age and immune system status).  Again, this is a vaccine, uniformly recommended and covered by insurance (as well as for the uninsured), without side effects on fertility, immune system function, or sexual activity/habits, that prevents multiple cancers (many of which have few or no symptoms until they spread), which are caused by a virus that most people WILL be exposed to in their lifetimes.  How does this add up???

October 9, 2018: Gardasil 9 now approved for men and women up to 45 years old!  The FDA announced on October 5 that it has approved an amendment to the labeling for Gardasil 9 to include older men and women, and now the vaccine can be given up until age 45.  This is a big deal because although we presume that most or all people are sexually active (and thus exposed to HPV) by their early 20s, this will allow uninfected people (who may be abstinent or not very sexually active) to receive protection until a much higher age.  Here’s the link:


Usual Pediatric Schedule:

  • 1st dose between 9 and 11 years old
  • 2nd dose 6-12 months later
  • If for some reason the series has not been started before age 15, a total of 3 doses are needed over a 6-12 month period)

Shingles Vaccine (This one’s for Parents and Grandparents; updated 8/2018)

Shingrix

Most of my posts will be about vaccines used in childhood, but there is an important one for many parents to be aware of that I’ve just become eligible for and many people are not yet clued into.  This is the newer version of the shingles vaccine.

What is it?

Shingles (i.e. zoster virus infection) is caused by the same virus that causes chickenpox in children, although we see a lot less of it now that there is an effective vaccine, available since the 1980s.

About varicella:

For most children, varicella is a mild but uncomfortable illness, causing fever, fatigue and blistering rash for most who still get it.  A small number of children are hospitalized for dehydration and a tiny number (about 1 in 10,000 of those infected) have a fatal complication.  Most of these fatal cases already have immune system problems before the infection develops.  Luckily, there is a very effective vaccine that almost all children get at 12-18 months old and again at 4-6 years old.  Receiving both doses of the vaccination is 88-98% effective in preventing any form of chickenpox and about 100% effective in preventing severe chickenpox.  It is routinely recommended and required for licensed daycare and school attendance, among other activities.

About shingles (hint: same virus but different symptoms in adults):

Once you get chickenpox, as most adults over 40 did as a child, the virus stays in your body but is kept dormant by your immune system.  As we age, our immune system slowly weakens and infectious conditions start to occur more easily.  Shingles is the condition that develops as the varicella-zoster (i.e. chickenpox) virus reactivates.  Initially one may have only severe pain, often in the abdominal region, chest or back.  Sometimes the pain may be so severe it is confused with appendicitis or a heart attack.  After several days, the pain improves but a rash develops in a particular pattern – it develops along the path of the sensory nerve that was harboring the virus for all those years.  The rash is most commonly red bumps and blisters, on only one side of the body, which can be painful, itchy or both.  The rash fades over time but the pain can be intense enough to need opiates.  After recovery, many people afterwards develop persistent pain, called post-herpetic neuralgia for months or years.  A family friend had this about 2 years ago and she still has fairly severe pain at times.

The older vaccine for adults (called Zostavax) was the same vaccine as we use to prevent chickenpox in children, only about 14 times stronger.  It was fairly effective and usually recommended for adults over 60.  For this reason, many people think of the shingles (or more properly the zoster) vaccine as a vaccine for the elderly.  Not true!!  The previous version was indeed generally recommended for those 60 and over but there is a newer, more effective version that is now recommended for adults age 50 and over (like my wife and me).  In fact, when given earlier, one has a more robust immune response, which means it works better when you receive it at a younger age.  The new vaccine is called “Shingrix” (ok, so no points for the name).  This is a new recommendation, so when calling your doctor’s office you may have to gently remind them that this is the new vaccine which is now given at a younger age (you can even send them the link below).  I strongly recommend this vaccine for all adults who are 50 and over.  It is safe and effective and should be covered by everyone’s medical insurance if they are over 50, even if they have already received Zostavax (the older version) in the past.

**Be aware, many doctors’ offices and retail pharmacies STILL do not have this in stock, even a year after its licensure.  I’m sure GSK (GlaxoSmithKlineBeecham) is doing everything in its power to increase their output, so hopefully it will not be long, but it would make sense to make a call to your doctor now, just to get onto a waiting list if possible.

See below for the excerpt from the CDC website at https://www.cdc.gov/vaccines/vpd/shingles/hcp/shingrix/recommendations.html

Here’s a post from the excellent blog Shotofprevention.com about needing this vaccine and how few adults are aware of it.

Summary of Recommendations

Routine Vaccination of People 50 Years Old and Older

CDC recommends Shingrix® (recombinant zoster vaccine) as preferred over Zostavax® (zoster vaccine live) for the prevention of herpes zoster (shingles) and related complications. CDC recommends two doses of Shingrix separated by 2 to 6 months for immunocompetent adults age 50 years and older:

Everything You Need to Know About Shingrix
[3:58 mins]
Dr. Kathleen Dooling discusses storage, administration, and patient counseling for the new shingles vaccine
Released: 4/30/18

  • Whether or not they report a prior episode of herpes zoster
  • Whether or not they report a prior dose of Zostavax
  • Who have chronic medical conditions (e.g., chronic renal failure, diabetes mellitus, rheumatoid arthritis, chronic pulmonary disease), unless a contraindication or precaution exists. Similar to Zostavax, Shingrix may be used for adults who are
    • are taking low-dose immunosuppressive therapy
    • are anticipating immunosuppression
    • have recovered from an immunocompromising illness
  • Who are getting other adult vaccines in the same doctor’s visit, including those routinely recommended for adults age 50 years and older, such as influenza and pneumococcal vaccines. The safety and efficacy of concomitant administration of two adjuvanted vaccines, such as Shingrix and Fluad, have not been evaluated.
  • It is not necessary to screen, either verbally or by laboratory serology, for evidence of prior varicella infection.

Breaking News: FluMist advised as a “last resort” by AAP but an “option” by the CDC for 2018-2019 season

In February 2018, the Advisory Committee on Immunization Practices (ACIP) of the CDC voted to once again recommend use of FluMist, the nasal spray flu vaccine, for the 2018-2019 influenza season.  Then, on May 21, 2018, the American Academy of Pediatrics came out with an official recommendation to use the injected form of the influenza vaccine over the newly resurrected nasal spray vaccine, and that the nasal spray should only be considered as a “last resort”.  This recommendation is due to a 3-year history of the nasal spray being of little value against influenza “A” strains in the last 3 seasons that it was used.  But really, “last resort”?  Given that this is going to be an approved vaccine, it’s hard to imagine a more negative ruling.  But the story gets better – read on…

This year, the maker of FluMist (MedImmune, a division of AstraZeneca) has changed the influenza A component to hopefully boost the response rate, but we will not know about the new vaccine’s effectiveness until several months after use begins in August.

Most people are thrilled to once again have the option of a nasal spray.  In general, children overwhelmingly prefer the nasal spray form as it does not cause pain nor does it involve using a needle.  Unfortunately, the AAP’s recommendation to use it only as a “last resort” puts many doctor’s offices in a bind, because decisions about which vaccine to order has to be made by May or June.  This is to ensure adequate supply and delivery in time to begin vaccination in late summer to early fall.  Ordering little or no nasal flu vaccine may backfire if patients are aware there is a choice and decide to wait until a nasal spray is available.  Alternatively, more patients may opt to receive the nasal spray vaccine at a Q-SHIP (quick-serve healthcare and immunization provider – my abbreviation!), such as CVS Minute Clinic.  This becomes a problem if such retail clinics also decide to under-order the spray, or if patients neglect to get this done once they have left the doctor’s office.  Historically, more children are vaccinated than adults, so the impact is greater on a pediatric office.  The disagreement between the CDC and the AAP is unusual, and this year will be interesting (to me) to see how the dissent pans out.

The nasal spray vaccine is approved for use in children 2 years and older, and for adults up to age 49.

Which would you choose????

Read the press release from the AAP here.

See a video by one of my vaccination heroes, Paul A. Offit, MD, from the Children’s Hospital of Philadelphia, here.

 

June 11, 2018: The Saga Continues…

Today the AAP released some amended recommendations on use of FluMist.  It acknowledged the differences in the recommendations between it and the CDC, and took a more moderate stance, stating that (italics added by me):

  • Annual influenza vaccination is recommended for everyone 6 months and older.
  • For the 2018-’19 season, the AAP recommends inactivated influenza vaccine (IIV3/4) as the primary choice for all children because the effectiveness of LAIV4:
  1. was inferior against A/H1N1 during past seasons; and
  2. is unknown against A/H1N1 for this upcoming season
  • LAIV4 may be offered for children who would not otherwise receive an influenza vaccine (and for whom it is appropriate by age and health status).
  • As always, families should receive counseling on these revised recommendations for the 2018-’19 season.

See the full press release here:

Note the “last resort” wording is conspicuously absent in this commentary.  This is what passes for intrigue in pediatrics!  Will be very interesting to see the effectiveness data when it starts to come out in the winter!!!!

But Wait, there’s more…

The CDC’s ACIP is also weighing in (again), with more detailed info on the new vaccine recommendations:

Recommendation of the ACIP:  For the 2018–19 U.S. influenza season, providers may choose to administer any licensed, age-appropriate influenza vaccine (IIV, recombinant influenza vaccine [RIV], or LAIV4). LAIV4 is an option for those for whom it is otherwise appropriate. No preference is expressed for any influenza vaccine product. ACIP will continue to review data concerning the effectiveness of LAIV4 as they become available. Providers should be aware that the effectiveness of the updated LAIV4 containing A/Slovenia/2903/2015 against currently circulating influenza A(H1N1)pdm09-like viruses is not yet known.

So now the CDC’s official position is that any of the age-appropriate flu vaccines are acceptable options, including FluMist (see here).  (Hooray from me!)  This difference of opinion between the AAP and the CDC is unusual (they almost always are in complete agreement) but both sides have valid points of view.   (For those who want the entire document, it’s posted here:)

July 2018: Now, even Canada is weighing in!  See the article from JAMA-Pediatrics here:

 

So I got my wish – everything is approved and everyone can have what they want.  Happy vaxxing!!


Usual Pediatric Schedule for influenza vaccine:

  • Every year for babies, children and adults 6 months and older; given from August to May; earlier is better
  • Children under age 9 years old receiving flu vaccine for the FIRST TIME get 2 doses, at least 1 month apart

Hepatitis B vaccine – for newborns and everyone else

  Recombivax                               Engerix

What is Hepatitis B?

Hepatitis B infection is a viral infection of the liver.  It can lead to jaundice, abdominal pain, liver failure, cirrhosis, and liver cancer.  Hepatitis B is extremely contagious and can be transmitted through intimate contact, by sharing IV drug use materials and any other method in which bodily fluids may mix, including sharing a tooth brush or a razor with someone who is infected or by becoming exposed to the blood or sores of an infected person.  Hepatitis B is many times more contagious than HIV in this respect, although not nearly as deadly.  Pregnant women can also pass the virus to their newborns.  Testing for Hepatitis B infection is done via a blood test.

 

Does Hepatitis B go away?

Many people who get infected with viral hepatitis (usually either Hepatitis A, B, or C, although there are other types as well) get mild symptoms or no symptoms at all and never realize they are sick; for most adults the viral infection goes away and they completely recover.   Hepatitis B and C have more potential to remain active and cause chronic infection, but this occurs in a minority of adults.  However, a larger number of children who get Hepatitis B develop chronic disease, and 9 out of 10 newborns who get hepatitis B during childbirth remain chronically infected for life unless the infection is prevented in the newborn nursery – see below.  Those who develop chronic Hepatitis B infection must be monitored for signs of liver failure and liver cancer for life.

 

The Hepatitis B vaccine

In 1981 the first vaccine to prevent Hepatitis B was licensed in the U.S.  It is given by injection and it is indicated for anyone at risk of contracting Hepatitis B, which is basically everyone.  Almost all newborns receive Hep B vaccine at birth, and if a pregnant woman is known to have Hep B infection, her newborn should receive both the vaccine and a dose of Hepatitis B Immune Globulin (HBIG).  When a newborn receives both HBIG and the full series of Hep B vaccines on time, the chances of preventing chronic infection are excellent.  The Hepatitis B vaccine was the first vaccine to be able to prevent cancer (now HPV vaccine also prevents cancer as well, but of the cervix).

 

What is the timing for Hepatitis B vaccination?

For infants and young children, Hep B vaccine is given in 3 doses: dose 1 (ideally on the day of birth), followed by dose #2 given 1-2 months later, and dose #3 given 6 months after dose 1.  For those who did not receive the Hep B vaccine series at birth, the same 0/1-2/6 month schedule is used for most older children and adults, but there is also a 2-dose schedule for older teens and adults and a different dosage for some people with chronic disease such as kidney failure.  In the U.S. today Hep B vaccine use for newborns is almost universal, but in other countries it is used much less consistently or not at all.

You can learn more about Hepatitis B infection and the Hepatitis B vaccine at the CDC’s Hep B website here.


Usual Pediatric Schedule:

  • 1st dose at birth (prior to hospital discharge)
  • 2nd dose at 1-2 months old
  • 3rd dose at 6 months old
  • **Many babies get 4 doses total in the first 6 months due to combination vaccines (less shots AND full protection)

Tdap vaccine for adolescents and adults (especially pregnant women)

Boostrix               Adacel

The Tdap vaccine, normally given to preteens, teens and adults, is different from the DTaP vaccine that we use in infancy and young childhood.  It protects against the same diseases (tetanus, diphtheria and pertussis), but the relative amount of each component is different.  We get asked about this a lot because it is given routinely to pregnant women during their third trimester and many times the rationale is not fully explained.

Some basics:  The vaccine protects against tetanus, diphtheria and pertussis.

-Tetanus is a bacterial infection commonly acquired through a contaminated wound. The bacteria often lives in dirt and in humans can produce a toxin that can cause severe muscle contractions.  The old term for tetanus was “lockjaw,” named for the severe clenching of the mouth that some patients developed.  Most people have never seen a person with tetanus, partially because the vaccine is so effective.  It advised to get a routine tetanus vaccine every 10 years, or after 5+ years if you get a dirty wound.

-Diphtheria is a bacterial infection that causes respiratory symptoms including cough and fever.  It can be severe, especially in the very young and old.  We see very little diphtheria in the U.S. today, but some countries that cut back on immunizing against it have seen a resurgence.

-Pertussis is also known as “whooping cough,” named after the sound that some people make when they have this infection.  Pertussis in most people causes a pronged coughing illness which can be quite contagious to their close contacts.  Some people with pertussis also develop fever, wheezing, and pneumonia.  Often it is not diagnosed because a doctor or nurse does not think of testing for it, as other causes of cough are more common.  Diagnosis requires a special test which takes a long time to get results.  It is treated with an antibiotic.  The biggest problem with pertussis is that it can be fatal for the elderly and for newborns.

 

Tdap vaccine is normally given only once to most people.  Preteens get it somewhere between 10 and 12 years old.  After that most people continue to get a “Td” vaccine, also just called a tetanus shot, every 10 years.  However, about 5 years ago, some obstetricians began giving Tdap vaccine to pregnant women.  The rationale for this was that the pertussis antibodies would pass through the placenta to the fetus and the baby would be born with some immunity (called passive immunity) from the mother’s vaccination.  Normally a baby is not given their first pertussis vaccine until 2 months old, so immunizing mothers during pregnancy gives the baby some protection until then.  This elegant strategy works very well, so now it is standard to immunize all pregnant women with Tdap with each pregnancy.  For those who never received a Tdap, having a newborn is a great excuse to push grandparents, aunts, uncles and fathers to get the shot they should have anyway, as well as anyone else who will have frequent contact with the newborn.  This would also apply to daycare workers, nannies, etc.

In the near future, we are likely to have an improved version of Tdap, and when we do it may replace Td for all adult doses. Stay tuned!!

Here’s a story from NPR regarding Tdap vaccine during pregnancy:


Usual Pediatric Schedule:

  • One dose only, at age 11-12 years
  • Pregnant women get a dose with EACH pregnancy, in 3rd trimester

Nasal spray flu vaccine (aka LAIV, or FluMist)

FluMist 5-pack     FluMist

Influenza prevention is getting more complicated, sort of. Until 15 years ago, the only way to prevent influenza was to get a flu shot in the fall and hope it would protect you from getting the flu.  The flu vaccine was grown in eggs and given annually.  Since then the options have expanded to include egg-free formulations, high-dose versions for older individuals, and a needle-free nasal spray.

In 2003 FluMist was approved for use  – a live attenuated influenza vaccine (LAIV) delivered as a spray into each nostril.  Intranasal administration made a lot of sense – this is the way that influenza virus enters the body and if we could create a barrier to entry, it would theoretically work better than waiting for the virus to enter the body before starting to fight it.  The big plus, of course, was that  it was not a shot.  This made it an immediate win with patients, especially kids.  For docs, it was faster to administer and easier to use – no needles, blood, bandages or sharps boxes.  Also, the back room management was easier, without need to draw fluid into a separate syringe.

However, although in some years the nasal spray vaccine worked well, there was a 2-year span when it seemed to work no better than a placebo.  Although there are differences of opinion as to why, with no evidence of protection, in 2016 the CDC had to pull its recommendation for use of this vaccine.  As a result, for the past 2 years, the only way to get vaccinated against influenza has been to get a shot.

For the influenza season starting in the fall (called the 2018-2019 flu season), FluMist is again on the list of possible vaccines for approval.  It will need to be approved based on data collected over the past 2 years, and although it’s not a sure thing, the CDC would certainly love to have a faster, painless product back in the office, and so would many patients.

Some basics about the nasal spray flu vaccine:

1. It is called FluMist (only 1 brand exists)

2. It is given as a tiny spray into each nostril

3. It is given in the same season that you would get any flu vaccine, August through May

4. It is approved for ages 2 years to 49 years (I’m too old for it now)

5. Many doctors are reluctant to use it in patients with asthma, as it makes an asthma exacerbation a little more likely in the few weeks after receiving it

6. It costs more than the cheapest injected flu vaccine but should be covered by insurance, including Medicaid, private insurance and government-provided insurance.


Usual Pediatric Schedule:

  • Can only be used in ages 2 years and older
  • Yearly dosing between August and May; earlier is better
  • Children receiving flu vaccine for first year ever get 2 doses, 1-2 months apart
