The U.S. Centers for Disease Control and Prevention provides a comprehensive chart of all recommended childhood immunizations on CDC.gov. The vaccine schedule begins with a hepatitis B immunization administered soon after birth and continues through late adolescence with a final booster shot recommended between the ages of 16 and 18.
As of January 1, 2015, the CDC recommends a schedule of approximately 30 vaccines for more than 15 diseases over the course of 18 years in addition to annual influenza vaccinations. Some of the vaccines are combined into one shot to inoculate for several illnesses at once. Diseases that CDC-recommended vaccines prevent include polio, measles, mumps, meningitis, hepatitis A, hepatitis B, rotavirus, tetanus, chicken pox and pertussis, also called whooping cough. With the exception of rotavirus vaccine, which is given as a drinkable liquid, all of the vaccines on the childhood schedule are routinely administered by injection.
Many of the vaccine-preventable illnesses can result in death if contracted, as the CDC reports. Among the potentially deadly diseases are hib, diphtheria, measles, pertussis, polio, pneumococcal and tetanus. Many vaccine-preventable illnesses can result in severe complications. Paralysis is a potential result of polio and diphtheria, and measles, chicken pox and mumps can result in encephalitis, or swelling of the brain.
