Vaccines (immunizations) are one of the safest and best methods of prevention. Immunizations are the best defense against serious illnesses for children and adults. We recommend following the American Academy of Pediatrics’ immunization schedule for your children. Immunizations can be administered to children with minor illnesses, such as an ear infection or runny nose. Children experiencing moderate to severe sickness should not receive some vaccinations, and those with other health conditions should not be given specific vaccines or receive them at a later date.
