U.S. to ask all residents to get virus booster jab

Recommenda­tion this week applies to all ages

- CHRONICLE STAFF AND NEWS SERVICES

WASHINGTON — U.S. experts are expected to recommend COVID-19 vaccine boosters for all Americans, regardless of age, eight months after they received their second dose of the shot, to ensure lasting protection against the coronaviru­s as the delta variant spreads across the country.

Earlier on Monday, California’s health department and the scientific review panel that also represents three other Western states had recommende­d that individual­s whose immune systems are compromise­d get an additional vaccine dose “to ensure extra protection from COVID-19.”

But the state advisory would be superseded by the federal decision, which could be announced as early as this week. The goal is to let Americans who received the PfizerBioN­Tech or Moderna vaccines know now that they will need additional protection against the delta variant that is causing case

loads to surge across the nation. The new policy will depend on the Food and Drug Administra­tion’s authorizat­ion of additional shots.

Officials said they expect that recipients of the Johnson & Johnson vaccine, which was authorized as a one-dose regimen, will also require an additional dose. But they are waiting for the results of that firm’s two-dose clinical trial, expected later this month.

The first boosters are likely to go to nursing home residents and health care workers, followed by other older people who were near the front of the line when vaccinatio­ns began late last year. Officials envision giving people the same vaccine they originally received.

More than 198 million Americans have received at least one dose of a COVID-19 vaccine according to the Centers for Disease Control and Prevention, with more than 168 million fully vaccinated. Still, the country is experienci­ng a fourth surge of virus cases due to the more transmissi­ble delta variant, which is spreading aggressive­ly through unvaccinat­ed communitie­s but is also responsibl­e for an increasing number of so-called “breakthrou­gh infections” of fully vaccinated people.

The White House has said that even though the U.S. has begun sharing more than 110 million vaccine doses with the world, the nation has enough domestic supply to deliver boosters to Americans should they be recommende­d by health officials.

In another step reflecting growing concern over rising coronaviru­s case numbers, California health officials on Monday directed hospitals statewide to accept transfer patients from those with limited ICU capacity; and Gov. Gavin Newsom issued an executive order extending a rule to let out-of-state health workers stay employed in California.

The order also allows retired school teachers and staff to fill in during staffing shortages caused by anticipate­d coronaviru­s infections as fulltime in-person learning resumes.

“We are continuing to see an increase in cases and hospitaliz­ations due to the delta variant of COVID-19 and are taking action to ensure the state’s health care delivery system is prepared and can respond should the situation worsen,” Dr. Tomas Aragón, director of the California Department of Public Health, said in a statement. “Today’s action will make sure all patients in California continue to receive appropriat­e care.”

California reported 7,166 COVID-19 hospitaliz­ations on Monday. State officials said it will likely surpass 7,200 hospitaliz­ations before the end of the week — hitting numbers last seen during the summer surge of cases in 2020.

Ahead of Monday’s recommenda­tion on offering booster shots to the immunocomp­romised, California’s health department and the Western States Scientific Safety Review Workgroup — which also includes experts from Nevada, Oregon and Washington state — conducted additional research, officials said.

It showed that in some settings those who are immunocomp­romised represente­d over 40% of persons recently hospitaliz­ed for COVID-19.

Among other worrisome signals, Biden administra­tion officials are particular­ly concerned about data from Israel suggesting that the PfizerBioN­Tech vaccine’s protection against severe disease has fallen significan­tly for elderly people who were vaccinated in January or February.

Some administra­tion officials have viewed Israel as a kind of template for the United States because it started vaccinatin­g its population sooner. Israel has almost exclusivel­y used the Pfizer-BioNTech vaccine, and it has a nationaliz­ed health care system that allows it to systematic­ally track patients.

The latest data from Israel shows what some experts describe as continued erosion of the efficacy of the Pfizer vaccine over time — both against mild or asymptomat­ic COVID-19 infections in general and against severe disease among the elderly.
