According to the European agency, the Omicron variant causes “mild” cases
“We need to gather more evidence to determine whether the spectrum of disease severity caused by Omicron is different from all the variants that have circulated so far,” said Marco Cavaleri, head of vaccine strategy at the Amsterdam-based EMA.
On Wednesday, the WHO had announced that the variant appeared to have a higher rate of reinfection, for people cured of the disease or vaccinated, while causing less severe symptoms. Anthony Fauci, the White House medical advisor, made the same observation earlier in the day. Pfizer and BioNTech emphasized the effectiveness of their current vaccine against the Omicron variant. However, a new formula is already in preparation.
