how many vaccines are required for children

Children are required to receive a schedule of vaccines that typically include around 13 injections protecting against 11 diseases, spread over several appointments from birth through adolescence. The vaccination course commonly protects against diseases such as hepatitis B, RSV, rotavirus, diphtheria, tetanus, pertussis, Haemophilus influenzae type B, pneumococcal disease, poliovirus, COVID-19, influenza, measles, mumps, rubella, varicella, and meningococcal infections, among others. The exact number of vaccines and doses depends on the child's age and health guidelines in their country, but the standard US schedule involves about 15 different immunizations by adolescence, including multiple doses of some vaccines across different ages.
