Immunizations, or vaccines as they're also known, safely and effectively use a small amount of a weakened or killed virus or bacteria or bits of lab-made protein that imitate the virus in order to prevent infection by that same virus or bacteria.
When you get an immunization, you're injected with a weakened form of (or a fragment of) a disease. This triggers your body's immune response, causing it to either produce antibodies to that particular ailment or induce other processes that enhance immunity.
With all the issues that come with raising an adolescent, it can be easy for parents to lose track of recommended preteen and teen immunization boosters.
Fortunately, the Advisory Committee on Immunization Practices (AICP) has recently updated its recommendations and immunization schedule for children 0-18 years old. The most current recommendations for preteen and teen immunizations include:
Tetanus and diphtheria toxoids and acellular pertussis vaccine (Tdap)
Tdap vaccine is usually administered...
Then, if you're ever again exposed to the actual disease-causing organism, your immune system is prepared to fight the infection. A vaccine will usually prevent the onset of a disease or else reduce its severity.
Why Should Someone Get Immunized?
The goal of public health is to prevent disease. It's much easier and more cost-effective to prevent a disease than to treat it. That's exactly what immunizations aim to do.
Immunizations protect us from serious diseases and also prevent the spread of those diseases to others. Over the years immunizations have thwarted epidemics of once common infectious diseases such as measles, mumps, and whooping cough. And because of immunizations we've seen the near eradication of others, such as polio and smallpox.
Some vaccines need to be given only once; others require updates or "boosters" to maintain successful immunization and continued protection against disease.
Which Immunizations Do My Children Need?
Because proof of immunization is often a prerequisite for enrollment in school or day care, it's important to keep your children up to date on their vaccines. The benefit of doing so is that your children will be protected from diseases that could cause them serious health problems. The recommended immunizations for children 0-6 years of age include:
Diphtheria, tetanus, pertussis
Haemophilus influenzae type B
Measles, mumps, rubella
Meningococcal (for certain high-risk groups)
At one time or another, each of the diseases addressed by these vaccines posed a serious health threat to children, taking their lives by the thousands; today most of these diseases are at their lowest levels in decades, thanks to immunizations.
It's important to keep your child's immunizations on schedule and up to date, but if your child misses a scheduled dose he or she can "catch up" later.The complete updated schedule of immunizations for children ages 0-18 can be downloaded from the CDC web site.
