The vaccine schedule
has become much more complicated than it once was. Children are receiving
far more shots than they ever did. Now, children could receive as many as
24 shots by 2 years of age and five shots in a single visit. Some parents
question the importance and safety of vaccines and whether their child
should receive so many at one time.
Parents should adhere to the vaccination schedule, for two reasons. The
first is to protect your child. Even if we think the chances of getting
any of these diseases are small, the diseases still exist and can still
infect anyone who is not protected.
Travelers are especially vulnerable. A few years ago a 63-year-old U.S.
traveler to Haiti caught diphtheria and died. He had never been
vaccinated. In 2005 and 2006, outbreaks of measles and mumps occurred in
several states within the U.S. The measles outbreak began in a group of
travelers (who had not been vaccinated) upon their return from a trip to
Romania where they had been exposed to measles.
The second reason to get vaccinated is to protect those around us. A small
number of persons cannot be vaccinated for medical reasons such as a
severe allergy to vaccine components. Another small percentage of people
simply do not respond to vaccines. These persons are susceptible to
disease, and their only hope of protection is that people around them have
been successfully vaccinated and cannot pass disease along to them.
A successful vaccination program, like a successful society, depends on
the cooperation of every individual to ensure the good for all. We
shouldn’t rely on people around us to stop the spread of disease if we
ourselves can be vaccinated.
Vaccine Myths
Myth No. 1: Diseases had already begun to disappear before vaccines
were introduced be cause of better hygiene and sanitation.
Better nutrition, not to mention the development of antibiotics and other
treatments, have increased survival rates among the sick; less crowded
living conditions have reduced disease transmission; and lower birth rates
have decreased the number of susceptible household contacts. But looking
at the actual incidence of disease over the years leaves little doubt of
the direct impact vaccines have had, even in modern times.
The real, permanent drop in case of measles in the U.S. coincided with the
licensure and wide use of measles vaccine beginning in 1963. Are we
expected to believe that better sanitation caused incidence of each
disease to drop, just at the time a vaccine for that disease was
introduced?
It’s clear that not only would diseases not be disappearing without
vaccines, but if we were to stop vaccinating, they would come back.
Myth No. 2: The majority of people who get disease have been
vaccinated.
It is true that in an outbreak those who have been vaccinated often
outnumber those who have not – even with vaccines such as measles, which
we know to be about 98 percent effective when used as recommended.
This is explained by two factors. No vaccine is 100 percent effective.
Most routine childhood vaccines are effective for 85 percent to 95 percent
of recipients. For reasons related to the individual, some will not
develop immunity. The second fact is that in a country such as the United
States the people who have been vaccinated vastly outnumber those who have
not.
Myth No. 3: There are “hot lots” of vaccine that have been associated
with more adverse events and deaths than others. Parents should find the
numbers of these lots and not allow their children to receive vaccines
from them.
The concept of a “hot lot” of vaccine as it is used in this context is
wrong. It is based on the presumption that the more reports to the Centers
for Disease Control and Prevention Vaccine Adverse Event Reporting System
(VAERS), a vaccine lot is associated with, the more dangerous the vaccine
in that lot; and that by consulting a list of the number of reports per
lot, a parent can identify vaccine lots to avoid.
This is misleading for two reasons. 1) A report made to VAERS does not
mean that the vaccine, or other vaccines from the same group or lot caused
the event. Only some of the reported health conditions are side effects
related to vaccines. A certain number of VAERS reports of serious
illnesses or death do occur by chance alone among persons who have been
recently vaccinated. VAERS reports have many limitations since they often
lack important information, such as laboratory results, used to
establish a true association with the vaccine.
2) Vaccine lots are not the same. The sizes of vaccine lots might vary
from several hundred thousand doses to several million, and some are in
distribution much longer than others. Naturally a larger lot or one that
is in distribution longer will be associated with more adverse events,
simply by chance. Also, more coincidental deaths are associated with
vaccines given in infancy than later in childhood, since the background
death rates for children are highest during the first year of life.
Reviewing published lists of “hot lots” will not help parents identify the
best or worst vaccines for their children. If the number and type of VAERS
reports for a particular vaccine lot suggested that it was associated with
more serious adverse events or deaths than are expected by chance, the
Food and Drug Administration (FDA) has the legal authority to immediately
recall that lot. To date, no vaccine lot in the modern era has been found
to be unsafe on the basis of VAERS reports.
Myth No. 4: Vaccines cause many harmful side effects, illnesses, and
even death – not to mention possible long-term effects we don’t even know
about.
Vaccines are very safe. Most vaccine adverse events are minor and
temporary, such as a sore arm or mild fever. These can often be controlled
by taking acetaminophen before or after vaccination. More serious adverse
events occur rarely (on the order of one per thousands to one per millions
of doses), and some are so rare that risk cannot be accurately assessed.
As for vaccines causing death, again so few deaths can be attributed to
vaccines that it is hard to assess the risk statistically. The Institute
of Medicine in its 1994 report states that the risk of death from vaccines
is “extraordinarily low.”
Myth No. 5: Giving a child multiple vaccinations for different diseases
at the same time increases the risk of harmful side effects and can
overload the immune system.
A number of studies have been conducted to examine the effects of giving
several vaccines at the same time. These studies have shown that the
recommended vaccines are as effective in combination as they are
individually, and that such combinations carry no greater risk for adverse
side effects.
There are two practical factors in favor of giving a child several
vaccinations during the same visit. First, we want to immunize children as
early as possible to give them protection during the vulnerable early
months of their lives. Second, giving several vaccinations at the same
time will mean fewer office visits for vaccinations, which saves parents
both time and money and may be less traumatic for the child.
Myth No. 6: The DTaP Vaccine causes SIDS.
One myth that won’t go away is that DTaP vaccine causes sudden infant
death syndrome (SIDS). This belief came about because a moderate
proportion of children who die of SIDS have recently been vaccinated with
DTaP; and on the surface, this seems to point toward a causal connection.
But this logic is faulty; you might as well say that eating bread causes
car crashes, since most drivers who crash their cars had probably eaten
bread within the past 24 hours.
Myth No. 7: Thimerosal causes autism.
Some parents are concerned that thimerosal, a mercury-containing
preservative still contained in the influenza vaccine, causes autism.
However, during the past few years a series of biological and
epidemiological studies have shown this concern to be unfounded.
Myth No. 8: Vaccine-preventable diseases have been virtually eliminated
from the United States, so there is no need for my child to be vaccinated.
It’s true that vaccination has enabled us to reduce most
vaccine-preventable diseases to very low levels in the United States.
However, some of them are still quite prevalent - even epidemic - in other
parts of the world.
Travelers can unknowingly bring these diseases into the United States, and
if we were not protected by vaccinations these diseases could quickly
spread throughout the population, causing epidemics here. At the same
time, the relatively few cases we currently have in the U.S. could very
quickly become tens or hundreds of thousands of cases without the
protection we get from vaccines
Lessening the Pain of Vaccines
For most children, getting vaccines simply means the pain of getting a
shot. Although pain is to some extent unavoidable, there are a few things
worth trying in older children.
Blowing away the pain: One technique is called “blowing away the
pain.” Just before the shot, take out a feather, tell the child to take a
deep breath, closing his eyes if he wants, and then blow out...blow, and
blow on the feather until you or the nurse tells them to stop. The
distraction of blowing on the feather has been shown in one study to
lessen the amount of pain perceived by the child.
Cold versus pain: Swab a small amount of alcohol on the forearm of
the same arm that will receive the vaccine. The child then blows on the
alcohol before and during the shot. Our bodies don’t feel cold and pain in
the same place at the same time.
Tylenol before, feeding afterward: For babies, a dose of
acetaminophen 30 minutes before and a bottle or nursing immediately
afterward can help minimize the pain of shots.
