The latest:

The U.S. Food and Drug Administration (FDA) on Wednesday authorized booster doses of COVID-19 vaccines from Moderna and Johnson & Johnson, and said Americans can choose a shot that is different than their original inoculation.

The decision paves the way for millions more people in the United States to get the additional protection with the highly contagious delta variant of the coronavirus causing breakthrough infections among some who are fully vaccinated.

The agency previously authorized boosters of the Pfizer-BioNTech vaccine at least six months after the first round of shots to increase protection for people aged 65 and older, those at risk of severe disease and those who are exposed to the virus through their work.

Last week, an advisory panel to the FDA voted to recommend a third round of shots of the Moderna vaccine for the same groups.

The panel also recommended a second shot of the J&J vaccine for all recipients of the one-dose inoculation at least two months after receiving their first.

The FDA and U.S. Centers for Disease Control and Prevention (CDC) were under some pressure to authorize the additional shots after the White House announced plans in August for a widespread booster campaign.

The advisory panel meeting included a presentation of data on mixing vaccines from a U.S. National Institutes of Health study in which 458 participants received some combination of Pfizer-BioNTech, Moderna and J&J shots.

The data showed that people who initially got J&J's COVID-19 vaccine had a stronger immune response when boosted with either the Pfizer or Moderna shot, and that "mixing and matching" booster shots of different types was safe in adults.

Many countries including Canada and the U.K. have backed mix-and-match strategies for the widely-used AstraZeneca-Oxford vaccine, which is not authorized in the United States but is based on similar viral vector technology as J&J's vaccine.

Reuters reported in June that infectious disease experts were weighing the need for booster shots of either the Pfizer or Moderna vaccine after the J&J shot.

A CDC advisory committee on Thursday will make its recommendations about which groups of people should get the Moderna and J&J boosters, which the agency's director will use to inform her final decision.

About 11.2 million people have so far received a booster dose, according to data from the CDC.

What's happening around the world

As of Wednesday, more than 241.6 million cases of COVID-19 had been reported around the world, according to the latest figures posted by Johns Hopkins University. The reported global death toll stood at more than 4.9 million, according to the U.S-based university's coronavirus tracker.

In Europe, Russia will shut workplaces for a week, Latvia went back into lockdown for a month and Romanian funeral homes are running out of coffins, as vaccine-skeptic ex-communist countries face record highs of infections and deaths.

In Africa, Kenya lifted a nationwide curfew on Wednesday that has been in place since March 2020 to curb the spread of the coronavirus.

In the Americas, 41 per cent of people across Latin America and the Caribbean have now been fully vaccinated against COVID-19, the Pan American Health Organization said.

In Asia, China reported a fourth day of new, locally transmitted cases in a handful of cities across the country, spurring local governments to double down on efforts to track potential carriers amid the zero-tolerance policy.
