After investigating reports of some people experiencing severe allergic reactions after getting inoculated with the vaccine against the coronavirus, the Centers for Disease Control and Prevention (CDC) , on Saturday, said that people who have a severe allergic reactions after the first dose should not get the second shot. The agency also advises those who have had severe allergic reactions to other vaccines or therapies consult their doctor before getting inoculated. Instead, people only known eith common allergic reactions can do it. There are known five severe reactions to Pfizer’s vaccine. The agency wasn’t sure what caused the reaction but it’s believed that a chemical called polyethylene glycol, which is present in Pfizer and Moderna’s coronavirus vaccine could be suspected.
“We’ll obviously be monitoring very closely what’s going on. We’re working very closely with the CDC on these, and there have been meetings between the CDC and FDA pretty much every day this week making sure we’re keeping very close track of what’s going on,” Peter Marks, director of the FDA’s Center for Biologics Evaluation and Research also said.The U.K.’s Medicines and Healthcare Products Regulatory Agency warned earlier this month that people with “significant” histories of allergic reactions should avoid getting Pfizer’s vaccine.
