Biden to Announce Plan to Buy 100 Million More Doses of J&J Vaccine

An additional 100 million doses of Johnson & Johnson’s single-shot COVID vaccine will be secured by the U.S. government by the end of the year, President Joe Biden plans to announce Wednesday.

The move means there should be enough doses on hand to vaccinate children and, if necessary, give booster doses or reformulate the vaccine to combat emerging, more contagious variants of the virus, The New York Times reported.

The announcement is expected to come during a White House meeting Biden will hold with executives from Johnson & Johnson and the pharmaceutical giant Merck, according to two senior administration officials, the Times reported. The rival companies are partnering to ramp up production of the Johnson & Johnson vaccine, in a deal brokered by the White House.

Biden has said that every American adult — roughly 260 million people — will have access to a vaccine by the end of May. But the senior officials, who spoke on condition of anonymity to preview the president’s announcement, said the administration was trying to prepare for unexpected challenges, the Times reported.

The officials said that they expected the doses to be delivered sometime in the second half of this year, but could not be more specific, the newspaper said. They added that Biden would direct officials at the U.S. Department of Health and Human Services to negotiate the details with Johnson & Johnson.

The Biden Administration has said the J&J/Merck collaboration will boost production and improve J&J’s packaging capacity, known in the vaccine industry as “fill-finish” — two big bottlenecks that have put the company behind schedule.

Biden has aggressively been working to acquire as much vaccine supply as possible, as quickly as possible. Before he took office, he pledged to get 100 million shots into the arms of Americans by his 100th day in office.

At the time, two vaccines — from Moderna and Pfizer — had been authorized by the U.S. Food and Drug Administration for emergency use. After his inauguration, Biden said his administration would have enough vaccine doses to cover every American by the end of summer. Last month, he announced the government had secured enough doses from those two companies to cover every American by the end of July. After the J&J vaccine was approved for emergency use recently, that timetable moved up to the end of May.

As of Wednesday, more than 61 million Americans have gotten one shot and over 32 million people are now fully vaccinated, according to the U.S. Centers for Disease Control and Prevention.

Pfizer vaccine not dampened by Brazil variant

Pfizer’s coronavirus vaccine neutralizes the more contagious P.1 variant of the virus recently discovered in Brazil, new research shows.

Pfizer and its German partner BioNTech conducted the study with scientists from both companies and researchers from the University of Texas Medical Branch. Blood samples from vaccinated individuals were tested against an engineered version of the Brazilian variant, the Washington Post reported. The samples came from participants in late-stage trials for the vaccine and were taken between two to four weeks after they received their second dose.

In the lab, the vaccine worked as well against the Brazilian variant as it did against the original virus, the Post reported. Last year, the vaccine showed 95 percent efficacy against the less contagious coronavirus strain. The findings were published March 8 in the New England Journal of Medicine.

Earlier research from British and Brazilian scientists that has not been peer-reviewed suggested that P.1 was more contagious and better able to evade vaccines than previous versions of the virus, the Post reported. The newer variant was first detected in January and has since spread from the Amazonian city of Manaus to multiple countries, including the United States.

In the United States, 15 cases of the Brazilian variant have been reported in nine states, according to the U.S. Centers for Disease Control and Prevention. That is far less than the 3,283 cases of the British variant that had been reported in 49 states as of Wednesday.

Another recent study on the P.1 variant, from researchers in Sao Paulo and at Washington University’s School of Medicine in St. Louis, discovered that the vaccine developed by Chinese drugmaker Sinovac was ineffective against P.1, raising alarm bells.

The study, a preprint posted online last week, tested the convalescent plasma of eight individuals immunized with Sinovac’s CoronaVac injection, which uses inactivated virus to stir an antibody response. The plasma samples failed to effectively neutralize the variant, researchers said.

New CDC guidelines give vaccinated Americans more freedom

New social distancing guidance released by the federal government on Monday gives fully vaccinated Americans more freedom to socialize and move through their communities.

The CDC said people who are two weeks past their final shot can safely visit indoors with unvaccinated members of a single household at low risk of severe disease without wearing masks or social distancing. That recommendation would free many vaccinated grandparents who live near their unvaccinated children and grandchildren to gather for the first time since the pandemic began a year ago.

The CDC also said fully vaccinated people can gather indoors with those who are also fully vaccinated, and they do not need to be quarantined or tested after exposure to COVID-19.

“We know that people want to get vaccinated so they can get back to doing the things they enjoy with the people they love,” CDC Director Dr. Rochelle Walensky said in an agency news release. “There are some activities that fully vaccinated people can begin to resume now in their own homes. Everyone – even those who are vaccinated – should continue with all mitigation strategies when in public settings. As the science evolves and more people get vaccinated, we will continue to provide more guidance to help fully vaccinated people safely resume more activities.”

Some restrictions were still advised, even for the vaccinated. For example, if a vaccinated person lives in a group setting and is around someone with COVID-19, he or she should still stay away from others for 14 days and get tested, even without symptoms.

Peter Hotez, co-director of the Texas Children’s Center for Vaccine Development, welcomed the new guidelines, but added they have been too long in coming.

“The sooner we move to telling people if you’re fully vaccinated, you don’t have to wear masks — that will be an incentive for people to get vaccinated,” Hotez told the Post.

The level of caution people need to exercise should be determined by the characteristics of those who are unvaccinated in a social setting, the CDC said. For instance, if a fully vaccinated person visits an unvaccinated friend who is 70, and therefore at risk of severe disease, the visit should also take place outdoors, with masks and physical distancing, the guidance says.

Advocates for older people embraced the new guidance, because many older people, especially those who live alone, have spent the past year in virtual isolation, they said.

Bill Walsh, vice president for communications for AARP, said that, “To the extent this allows people, grandkids, families, loved ones in nursing homes or assisted living [to interact], we welcome that,” he added. “We’ve heard over the past year some heart-wrenching stories of family separation.”

A global scourge

By Wednesday, the U.S. coronavirus case count passed 29.1 million while the death toll passed 527,000, according to a Times tally. On Wednesday, the top five states for coronavirus infections were: California with over 3.6 million cases; Texas with more than 2.7 million cases; Florida with over 1.9 million cases; New York with more than 1.7 million cases; and Illinois with over 1.2 million cases.

Curbing the spread of the coronavirus in the rest of the world remains challenging.

In India, the coronavirus case count was nearly 11.3 million by Wednesday, a Johns Hopkins University tally showed. Brazil had over 11.1 million cases and more than 268,000 deaths as of Wednesday, the Hopkins tally showed.

Worldwide, the number of reported infections passed 117.6 million on Wednesday, with more than 2.6 million deaths recorded, according to the Hopkins tally.
