Europe's medicines regulator said it was reviewing if there was a risk of a rare inflammatory condition after inoculation with Covid-19 vaccines, following a report of one case with Pfizer/BioNTech's shot.

The European Medicines Agency's (EMA) safety committee is looking into multisystem inflammatory syndrome (MIS) after a 17-year-old male in Denmark reported the condition, the regulator said, adding that the teenager had since fully recovered.

The panel is also looking into cases of blood clots in veins with Johnson & Johnson's Covid-19 vaccine, the regulator said, adding that the issue was distinct from a rare side-effect identified earlier.
