Operation Warp Speed’s coordinator Dr. Moncef Slaoui announced on Tuesday that COVID-19 vaccine candidates produced by Pfizer and Moderna are safe, as barely between 10% and 15% of volunteers listed “significantly noticeable” side effects.
Slaoui disclosed that the side effects could last up to 36 hours, and incorporate redness and pain at the injection site, fever, chills, muscle aches and headache.
“The longer, more important kind of adverse events such as some autoimmune disease or others have not been reported in a different way between the placebo group and the vaccine group in these two trials, which is very reassuring,” Slaoui told the Washington Post.
