CDC Expands Booster Recommendation (6 a.m. HK)

The U.S. Centers for Disease Control and Prevention is now recommending booster shots for all vaccinated people 18 and older as scientists race to study the emerging omicron variant of SARS-CoV-2.

The guidance, which previously said adults “may” get boosters, now says they “should” get a third dose of the Moderna Inc. or Pfizer Inc. shot six months after their second dose.

N.Y. Doesn’t Plan Mask Mandate (4 p.m. NY)

New York Governor Kathy Hochul said there were no reported cases of the omicron variant in the state but she was monitoring infections found nearby in Ontario, Canada. At a briefing Monday, she said she was focused on getting more of the state vaccinated and planned to tap its National Guard to help administer booster shots at nursing homes.

Hochul said she has no plans for a statewide mask mandate, preferring a targeted approach to restrictions that are guided by local officials. She also called out the stark divide in cases between Upstate regions -- which account for most of New York’s recent Covid hospitalizations -- and the rest of the state. Downstate hospitals are sending workers to help upstate, she said, adding guardsmen could provide help too.

More than 78% of New Jersey’s population has received at least one dose of the Covid-19 vaccine, higher than the U.S. total of 69.7%. The unvaccinated continue to make up most of the hospitalizations, Murphy said.

Doctor Who Saw Omicron Says Symptoms Milder (7:04 a.m. NY)

People infected by omicron in South Africa are showing very different symptoms to those suffering from the delta strain, said the doctor who alerted government scientists to the possibility of a new variant.
