(Reuters) — Pfizer Inc PFE.N said on Tuesday participants were showing mostly mild-to-moderate side effects when given either the company’s experimental coronavirus vaccine or a placebo in an ongoing late-stage study.

The company said in a presentation to investors that side effects included fatigue, headache, chills and muscle pain. Some participants in the trial also developed fevers — including a few high fevers. The data is blinded, meaning Pfizer does not know which patients received the vaccine or a placebo.

Kathrin Jansen, Pfizer’s head of vaccine research and development, stressed that the independent data monitoring committee “has access to unblinded data so they would notify us if they have any safety concerns and have not done so to date.”
