Dr. Natasha Burgert is well aware of the concerns parents have about the Covid-19 vaccines.

The Kansas pediatrician, who is a spokesperson for the American Academy of Pediatrics, said she’s already been counseling some parents about their fears. And she worries that they are entering a particularly sensitive time — one that anti-vaccination activists could exploit.
