Iran Press/ Europe: Britain hailed “V-Day” when it became the first country to roll out the Pfizer-BioNTech COVID-19 vaccine. Yet, as a first mover, it has also become the first to report cases of adverse reactions, allowing other nations to watch and learn, Reuters reported.
Anaphylaxis is an over-reaction of the body’s immune system, which health specialists describe as severe and sometimes life-threatening. While such allergic reactions are rare in any individual vaccine recipient, they are not unusual during large-scale rollouts, scientists, experts, and industry figures said.
The reports nonetheless led to Britain’s Medicines and Healthcare products Regulatory Agency (MHRA) beefing up its guidance for the shot at midnight leading into Thursday, specifically warning that anyone with a history of anaphylaxis should not take it.
