Is the COVID-19 vaccine safe? What are the risks?

Dr. Peter Hotez says there should be minimal concern regarding allergic reactions to the COVID-19 vaccine produced by Pfizer and BioNTech.

"When we vaccinate people, allergic reactions are not uncommon, they do occur. And sometimes even severe reactions, but they're extremely rare. We're talking on the order of one in a million," Hotez said.

He says the Pfizer vaccine is safe.

The Pfizer vaccine is 95% effective and protects men and women equally, along with people of different races and ethnicities.

It's safe for people who are 16 and older to receive.
