Vaccines and Adolescent Development
Young children get a large number of vaccines, which help protect them from disease as they grow. But as children become adolescents, they need new immunizations to make sure they stay healthy. This is important because some illnesses become a bigger threat as children get older. No matter how healthy an 11- or 12-year-old is, up-to-date vaccinations are a must.
Vaccines are medicines, usually given as shots, that prepare the body to fight an infection. They have the same germs, or parts of the same germs, as the diseases they prevent. The difference is that they are weak or dead versions of those bacteria or viruses, so they will not make you sick. They do, however, give your immune system the tools, called antibodies, it needs to guard against those germs if you are exposed to them in the future.
Any medical visit provides a perfect opportunity to check that preteens' and teens' immunizations are up to date. Unless an adolescent has an allergy or other medical condition that makes getting these shots too dangerous, the CDC recommends that they should receive four important vaccines starting at age 11 or 12:1
- Tetanus, diphtheria, and pertussis vaccine (1 dose): a booster to protect against these three infectious diseases (pertussis is also called "whooping cough")
- Meningococcal conjugate vaccine (2 doses) (MCV4, or MenACWY): an immunization to protect against meningococcal disease (like meningitis or sepsis, a blood infection)
- Human papillomavirus (HPV) vaccine (2 doses) (Cervarix or Gardasil): this immunization prevents many HPV-related cancers that occur later in life. It is recommended for both boys (Gardasil only) and girls (Cervarix or Gardasil).
- Influenza (flu) vaccine (every year): a vaccine that is recommended yearly for everyone over 6 months old to protect against different strains of seasonal influenza
Adolescent immunization rates vary by vaccine type and demographic characteristics
The proportion of adolescents receiving immunizations on time has increased each year between 2006 and 2014. In 2014, coverage rates of the three adolescent-specific vaccines were 88 percent for tetanus, diphtheria, and pertussis; 79 percent for meningitis; and HPV vaccine coverage rates of at least one dose were 60 percent for girls and 42 percent for boys. By comparison, rates for most recommended early childhood vaccines are at or above 90 percent. Adolescents living in the southeastern United States are significantly less likely to receive the three adolescent-targeted vaccines than are teens living in other regions of the country.2
The HPV vaccine is the most recently recommended of the three adolescent-specific immunizations, and has lower coverage rates among teens than the other recommended vaccines.3 Overall, in 2014 about 40 percent of girls and 22 percent of boys ages 13-17 received at least three doses of the HPV vaccine,4 well under the Healthy People 2020 target of 80 percent. The adoption and follow-through of the HPV vaccine also varies by racial/ethnic group; Hispanics and American Indian/Alaskan Natives are more likely to receive at least one dose, and to receive more than one dose, compared with non-Hispanic whites.5
