Woman's severe reaction to Pfizer COVID vaccine prompts investigation

Fears over the vaccine's safety were prompted by a video of a woman suffering convulsions after receiving a Pfizer coronavirus jab in Louisiana. In an exclusive interview with RT, Brant Griner, son of the affected person, says that she hadn't experienced any health issues before taking the shot, and added that the response he'd received to his video about it suggests his mum's case isn't a one-off.
