Is there a link between vaccines and autism?
by Dr. Robert Sears, MD, FAAP
 When
it comes to making vaccination decisions, autism is the main
worry on every new parent's mind. On one side of the debate,
we have 99% of the medical community and researchers worldwide
reassuring us that vaccines have no link to autism. On the other
side are tens of thousands of parents who have watched their
children regress into autism between age 1 and 2. And these parents,
including celebrities like Jenny McCarthy, are becoming more
and more vocal about what their “mommy instinct” is
telling them.
Honestly, I've read ALL the research, and both sides present
good data and good arguments. I'm not sure who is right at this
point. Until I see enough evidence showing vaccines are linked
to autism, I certainly am not going to tell anyone that vaccines
contribute to autism. But, at the same time, I can't say for
sure that vaccines absolutely do NOT play any role at all in
contributing to autism.
So what should parents do? It would seem you have two choices:
Either you continue following the standard recommended vaccination
schedule so your child has disease protection while this issue
is studied, which will probably take at least a few years, or
you stop vaccinating until further research gives us answers
one way or the other.
For those of you who are considering declining vaccines altogether,
I would at least like to make you aware of the option that I
call Selective Vaccination.
SELECTIVE VACCINATION
My Selective Vaccination Schedule gives your
child the most crucial shots at the age when they are most
needed while leaving
out the shots that tend to have more severe or more frequent
side effects. It omits vaccines for diseases that are usually
mild, don’t occur during young childhood, don’t exist
in our country, or are fairly rare. (These shots are still important
for the immunity of our nation as a whole, they just don’t
fit all the criteria choosy parents have).
This Selective Vaccination Schedule calls for only two shots
at a time and only one aluminum-containing vaccine at a time,
and every shot listed fits at least two of the three criteria
I use in deciding which vaccines are the most important:
1. The disease is likely to be very severe (fatal, permanently
disabling, or requiring hospitalization).
2. The disease is not only severe, it’s
also fairly common.
3. The vaccines have the lowest probability of causing a severe
reaction and have as few controversial ingredients as possible.
Dr. Bob’s Selective Vaccination Schedule
2 months DTaP, Rotavirus
3 months Pc, HIB
4 months DTaP, Rotavirus
5 months Pc, HIB
6 months DTaP, Rotavirus
7 months Pc, HIB
15 months Pc, HIB
5 years Tetanus booster
10 years Blood tests (called “titer” tests) for measles, mumps,
rubella, chickenpox, and Hep A immunity. If a titer is positive, showing
your child acquired immunity through natural exposure, he may not need the
shot,
but consider vaccinating if not immune.
Also consider a 3-dose polio series if travel to Africa or Asia is a possibility.
11 years *HPV (3 doses, girls only). *Note: This vaccine is too new for me
to sign off on completely. Read my note under, “Why These Shots?”
12 years Hep B (3 doses)
WHY THESE SHOTS?
DTaP
Although diphtheria and tetanus don’t fit my criteria,
pertussis certainly does. It’s common, it’s potentially
severe in the first year of life, and the side effect profile
of the vaccine is acceptable. The ingredients do include some
chemicals, but overall it fits most of the criteria. The eighteen-month
DTaP that is normally recommended isn’t as critical after
the first year of life, so I don’t include it here. The
tetanus booster is shown at age five to provide protection for
the growing child.
Rotavirus
Rotavirus is certainly common, potentially severe for infants,
and the ingredients and known side effects of the vaccine so
far are reasonable.
Pc
Pneumococcus is a very common germ, yet most cases are fairly
mild. Severe cases of Pc are uncommon but do occur. The side
effects and ingredients of the vaccine are acceptable.
HIB
HIB is a severe disease when it does strike, but fortunately
it is extremely rare now. The ingredients and side effects
of the vaccine seem to be among the safest of all shots.
HPV
HPV is an important disease to try to prevent, but the vaccine
is also very new. If the safety and effectiveness of the HPV
vaccine pan out over the next couple of years, then I will
probably keep it on my list. Visit www.TheVaccineBook.com for
updates.
Hep B
Although hepatitis B is very severe when it occurs in babies
and children, it is rare in that age group and the listed vaccine
side effects do include some potentially bad reactions, so
I didn’t put it on my list for infants. I do, however,
put it on the list for preteens. It’s important to note
that I recommend most of these shots be given during the ages
when they are most needed—infancy for the first four
vaccines and the preteen years for the last two. It wouldn’t
make much sense to wait until age one or two to give the infant
shots because the child is way past the age when these illnesses
tend to strike and strike hard. I also realize that parents
who do not wish to vaccinate think their kids don’t need
hep B or HPV protection until the teen years (or never at all
for those with perfect children), so I don’t push until
the shots become more relevant.
WHAT ABOUT THE REST?
Here are my reasons for not including the rest of the shots:
Polio
This disease doesn’t occur in the United States, and its
ingredients include more chemicals than most vaccines as well
as some blood products (although the side effects of the shot
seem mild).
Flu
Because of some of the ingredients and the high percentage of
reactions from this vaccine, I don’t put it on the list.
Although it is a very common illness, and it does cause many
hospitalizations, infant and child fatalities are rare.
MMR
For the most part, measles, mumps, and rubella are (or used to
be) routine childhood illnesses with very few problems. These
diseases are now fairly rare. And while side effects are rare,
the side effect profile for this vaccine is the longest and
most potentially severe of all the shots. Some research has
shown that the measles virus in the MMR vaccine, which is given
at age 1, may be one of the "triggers" that begins
the cascade of intestinal inflammation that leads to brain
inflammation and autism, but as I mentioned before, there is
currently no conclusive proof to confirm or refute this.
Chickenpox
Although still very common, this illness is usually mild. There
are some notable side effects and unusual ingredients in the
vaccine that worry choosy parents.
Hep A
This disease is somewhat common, but most childhood cases are
mild. The vaccine ingredients do include some chemicals and
unusual components, and the potential seizure side effect is
also something to consider.
Meningococcal vaccine
A severe disease, but it’s fairly uncommon. The ingredients
of this vaccine are safe, but the very rare side effect of Guillan-Barré syndrome
is something to consider. Also, I don’t include this vaccine
on the list because it is so new. If the safety profile continues
to look good after several years, I may add this vaccine to the
selective list for teenagers. Once it is found to be safe and
effective and approved for younger children, I may eventually
add it to the selective list at age two. For updates, visit www.TheVaccineBook.com.
THE RIGHT CHOICE FOR YOUR CHILD
I encourage parents to educate themselves about vaccines and
diseases, so they can make their own informed decisions about
what’s best for their children. I wrote The Vaccine Book
and started a website (www.TheVaccineBook.com) to help parents
get the answers they need in order to have more informed discussions
with their pediatricians. I also want both parents and doctors
to understand that there are alternatives to the “all or
nothing” debate and that an educated decision is the best
decision for your child, no matter what choice you make.
