coronavirus vaccine has revealed there are no serious side effects of the jab. Ugur Sahin, chief executive of BioNTech, announced promising preliminary results of its vaccine with Pfizer - which was found to be 90% effective in preventing Covid-19 infection.
He said the “key side effects” seen so far were mild to moderate pain in the injection site for a few days, while some of the participants had a slight fever for a similar period.
In an interview on BBC One's Andrew Marr Show, Proffessor Sahin said the side effects of the vaccine were not enough to stop the study.
