Those hesitant to get a COVID-19 vaccine sometimes have basic questions such as, what's in it.

The answers are not quite as easy to come by as the frequent public health messages about where and how to get a vaccine. But they are available.

Dr. Rupali Limaye, a scientist at Johns Hopkins Bloomberg School of Public Health, where she directs behavioral and implementation science at the International Vaccine Access Center, said such concerns have existed for previous vaccines as well.

Limaye said, "Parents specifically were concerned about the types of ingredients that were in a vaccine," and Limaye said this long-standing concern exists with the new vaccines.

"It's just that we're in the middle of a pandemic, and so I think there's a lot more scrutiny on this vaccine compared to other vaccines that also went through the [Emergency Use Authorization] process, even though it'll go through a full approval process," she said.
