Adhering to the recommended childhood vaccination schedule remains the best method for preventing contagious childhood illnesses and protecting the health of children. Children ranging in age from newborn to 18 years are vaccinated to ensure the most complete disease protection possible. While even full vaccination will not prevent every potential childhood sickness, it does reduce the vast majority of problematic and even potentially fatal contagious diseases. Furthermore, serious side effects from vaccines remain extremely rare, varying from about one in 100,000 to one in 1 million immunizations, depending on the specific vaccine. #bakunanay
