Public education programs directed at increasing parental knowledge about are badly needed in the united states.

the importance and safety of timely immunizations

Explanation:

Immunizations will dramatically improves humans' resistance toward a certain type of disease, but the effect is not 100% guaranteed (But it's pretty close). The scientific consensus has determined that immunizations are safe with reallly really small percentage of complications. (even if the complications occurs, the benefits still heavily outweigh the negative effects)

The number of parents that still doubt the effect of Vaccine is pretty high in united states. As per june 2019, Surveys shows that around 45% of American adults still doubt vaccine's safety.

This number is really concerning because not only that children who never receive immunizations will be exposed to dangerous health risks, it also improve the chance of other children from getting it too, even if those other children are immunized.
