submitted an amendment to the emergency use authorization it’s seeking from the U.S. Food and Drug Administration for a booster shot of its COVID-19 vaccine. The amendment offered additional data showing the booster increased protection to 94% against moderate-to-severe or critical COVID-19 in patients aged 18 and older in the U.S.

The submission includes recent data from a Phase 3 trial that found the booster given 56 days after primary dose provided 94% protection against symptomatic illness in moderate to severe/critical COVID-19 and 100% protection against severe/critical COVID-19, at least 14 days post-booster vaccination.

It also includes Phase 1/2 data that shows a booster given six months after the single shot vaccine increases antibody levels ninefold one week after administration that climbs to 12-fold higher four weeks after. J&J is planning to submit the data to other regulatory agencies and the World Health Organization.

Russia counted 895 new COVID-19 deaths on Tuesday, the most since the start of the outbreak and continuing a streak of record tolls, Reuters reported. The Kremlin is blaming the trend on the slow pace of vaccinations and a more virulent virus variant, delta.

“The numbers are really very bad, and this is indeed a cause for concern. The main reason is the insufficient level of vaccination,” said Kremlin spokesman Dmitry Peskov. Russia has fully vaccinated 42.2 million people out of 142 million and needs to inoculate at least 35.9 million more to achieve collective immunity.

The U.S. is still averaging c lose to 2,000 COVID-19 deaths a day, according to a New York Times tracker, although hospitalizations and new cases are on the retreat after a surge in the summer months caused by the delta variant. Most deaths, cases and hospitalizations are in unvaccinated people, and experts continue to urge those people to get their shots.

California has deployed National Guard troops to hospitals in rural north and central area of the state to help overwhelmed hospitals cope, the Guardian reported. The move has highlighted the disparities within the nation’s most populous state between those with easy access to vaccines and those without. agricultural heartland in the Central Valley and its sparse, rural north have case rates that are three or four times higher.

Elsewhere, Norway and Portugal are the latest countries to offer booster vaccine jabs to people aged 65 and older, the Guardian reported separately. The European Medicines Agency has recommended that people with weakened immune systems be offered a booster but has left it to individual countries to decide on other patient groups.

India’s Supreme Court has ordered India’s disaster management agency to pay 50,000 rupees, about $671, to families of people who have died from COVID, the New York Times reported. India’s official toll from the pandemic is 449,260, although experts estimate that the true number of fatalities is far higher.

Australian Prime Minister Scott Morrison said his country will not be welcoming international tourists until 2022, because it will prioritize students and skilled migrant workers first, the Washington Post reported. The country last week set out plans to allow vaccinated citizens to return home from overseas.
