Vaccinations for children are a critical part of their healthy development. However, many questions have arisen surrounding these shots over the last few years. Parents wonder when, and sometimes if, they should vaccinate their children.
H. Cody Meissner, MD, Chief of Pediatric Infectious Diseases at Tufts Children's Hospital at Tufts Medical Center and a national expert on the vaccinations and the flu, answers questions to help parents best understand how to care for their children.
What are the benefits and risks of childhood vaccinations?
Every human activity from riding in a car to eating an egg carries some risk. There is no such thing as a risk free activity. The risks associated with immunization are either so minor (sore arm) or so rare (seizure), they are far outweighed by the lives saved and the illness prevented by immunization. Do the benefits of avoiding infection outweigh the potential side effects? Yes. For each vaccine, the benefit clearly outweighs the risks.
What would happen if we stopped vaccinating?
Before long we would see epidemics of diseases that have disappeared or are nearly under control now. This is because the germs that cause these diseases are still around us but controlled by vaccines. Vaccine preventable diseases may be either eliminated or very uncommon, but the bacteria and viruses that cause these diseases are still present so it is important for every child to continue to receive all recommended vaccinations.
What vaccinations should every child receive?
The following immunizations are recommended for all children in the United States:
- hepatitis A,
- hepatitis B,
- Haemophilus influenzae type b,
Is there a link between vaccines and Autism?
There is no scientific evidence to support the existence of a link between any vaccine and autism. In fact, many scientific studies show there is no link between vaccines and autism.
What should I know about components in vaccinations that may be harmful?
Thimerosal is mercury containing preservative used in some vaccines since the 1930s. There is no convincing scientific evidence of harm caused by the low doses of thimerosal used in vaccines except for minor reactions like redness and swelling that sometimes occur at the injection site. Since 2001, all vaccines recommended for children six years of age and under in the United States have been produced without thimerosal as a preservative, with the exception of inactivated influenza vaccine. There is no scientific proof of any adverse consequence from the small amount of aluminum in any vaccine.
Should I delay when my child has certain vaccinations?
The recommended immunization schedule from the CDC and the American Academy of Pediatrics has evolved over many years with much deliberation. The recommended time for administration of each immunization is provided in this schedule. Parents should work hard to comply with the recommended schedule to be certain their children are protected against any of the vaccine preventable diseases. Any delay in administering a recommended vaccine will leave your child susceptible to that vaccine-preventable disease until the vaccine is administered.
How can I best protect myself and my child from getting this infection?
The best way to prevent the flu is by getting a flu vaccination each year. Yearly flu vaccination should begin in September or as soon as vaccine is available and continue throughout the influenza season, into December, January, and beyond. This is because the timing and duration of influenza seasons vary. While influenza outbreaks can happen as early as October, most of the time influenza activity peaks in January or later.
Everyone should reduce their chances of getting the flu by getting vaccinated. However, certain people should get vaccinated each year either because they are at high risk of having serious flu-related complications or because they live with or care for high risk persons. It is recommended that all children aged six months to 19 years get vaccinated each year.
Here are some steps you can take to reduce the risk of getting influenza:
- Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it. If a tissue is not available, you should cough into your elbow and not your hands.
- Wash your hands with soap and water, especially after you cough or sneeze. Alcohol based hand cleansers are also effective.
- Avoid touching your eyes, nose and mouth. Germs spread this way.
- Try to avoid close contact with sick people.
- Stay home if you are sick until you have been symptom-free for 24 hours. This is to keep from infecting others and spreading the virus further.
