Severe obesity may weaken the effectiveness of COVID-19 vaccines in those who have never been infected with the coronavirus, according to a small Turkish study.

The Omicron variant of the SARS-CoV-2 virus is intrinsically as severe as previous variants, unlike assumptions made in previous studies that it was more transmissible but less severe, a large study in the United States found.

Moderna Inc. on May 4 forecast higher vaccine sales for the second half of 2022 than in the first six months of the year, as the company expects the virus that causes COVID-19 to follow a more seasonal pattern requiring booster shots in the fall.

Asthma in children may worsen after an infection with the coronavirus, doctors warn.
