This is especially true for children, who are more vulnerable to diseases because of their underdeveloped immune systems. When they are vaccinated, they develop infection-fighting antibodies that protect them from many diseases as they grow up. It also contributes to herd immunity, which prevents the spread of diseases, even for those who are not vaccinated.
According to the Centers for Disease Control and Prevention (CDC), routine vaccinations during childhood help prevent 14 diseases. For children born from 1994 to 2018, it will inhibit an estimated 936,000 early deaths, eight million hospitalizations, and 419 million illnesses.
