Health & Fitness FDA clears Johnson & Johnson COVID-19 vaccine for emergency use
Pfizer developing new vaccine form that won't need ultra-cold storage
Pfizer Inc CEO Albert Bourla said, on Tuesday, that scientists are currently working on a new formulation of the jab that can be kept in a refrigerator for several months. Pictured: A vial of the Pfizer-BioNTech COVID-19 vaccine at the Northern General Hospital in Sheffield, Yorkshire, December 8 Bourla explained that engineers at Pfizer have developed special boxes to ship the vaccine at extreme temperatures once it is approved and shipped from Kalamazoo, Michigan.
The U.S. Food and Drug Administration (FDA) authorized Johnson & Johnson's COVID-19 vaccine for emergency use on Saturday (Feb. 27), making it the third shot cleared for use in the country.
"The authorization of this vaccine expands the availability of vaccines, the best medical prevention method for COVID-19, to help us in the fight against this pandemic, which has claimed over half a million lives in the United States," Acting FDA Commissioner Dr. Janet Woodcock said in a statement.
A Guide To The Covid-19 Vaccine If You're Pregnant Or Breastfeeding
People who are either pregnant and deemed high-risk from Covid-19, or breastfeeding, have now been given the go-ahead to have the Covid-19 vaccine in the UK – despite previously being told they shouldn’t have it. Although it seems like positive news, there hasn’t been a change in evidence in terms of the safety of such vaccines for these groups. It’s likely to be a confusing U-turn for those who were explicitly told they couldn’t have the vaccine and were gearing up to batten down the hatches for months while carrying their baby, and possibly years after, if breastfeeding.So what do you need to know?Related...
An FDA analysis showed that the single-shot vaccine had a 72% overall efficacy rate in the U.S. and 64% in South Africa, where a highly-transmissible coronavirus variant is causing most new cases,. The efficacy rate in South Africa is slightly higher than the company had , up by seven percentage points.
In terms of protecting against severe disease, the vaccine showed 86% efficacy in the U.S. and 82% in South Africa, the Times reported.
And the shot was "100 percent effective in preventing hospitalization and deaths, and that's really what's important," Dr. Nancy M. Bennett, a professor of medicine and public health sciences at the University of Rochester School of Medicine and Dentistry,. "Those facts are the most important thing to recognize."

Johnson & Johnson also monitored for asymptomatic infections by checking for coronavirus antibodies in a small number of volunteers 71 days after they got either the vaccine or a placebo shot. The data shows that the vaccine has 74% efficacy against asymptomatic infections, but "there is uncertainty about the interpretation of these data," given the small number of volunteers assessed, the FDA noted, according to the Times.
Despite having a lower overall efficacy rate than theand vaccines, which are each more than 90% effective, the single-shot vaccine could still make a big difference because it can be stored for months at refrigerator temperatures, rather than requiring deep-freezing, .
Additionally, the vaccine shows more than 80% efficacy against severe disease and 100% efficacy against hospitalization; this level of protection can prevent trips to the(ICU), thus lessening the burden on health care systems, as well as help vaccinated people avoid the potential of severe COVID-19 infection.
How Oxford scientists developed a Covid-19 vaccine in record time
Experts involved in the inoculation race explain how the jab was developedThe pandemic is only a year old, but we already have multiple vaccines available to fight Covid-19 – including the vaccine developed by the team we’re part of at the University of Oxford.
"Don't get caught up, necessarily, on the number game, because it's a really good vaccine, and what we need is as many good vaccines as possible," Dr. Anthony S. Fauci,the Biden administration's chief medical adviser on COVID-19,on Saturday (Feb. 27). "Rather than parsing the difference between 94 and 72, accept the fact that now you have three highly effective vaccines. Period."
Similar to the vaccine developed by the University of Oxford and AstraZeneca, the Johnson & Johnson shot contains a weakened version of a common cold virus, known as an adenovirus,. Scientists genetically altered the adenovirus, named ad26, so it can no longer infect human cells and then added genes that code for the coronavirus , a structure that sticks off the pathogen's surface and helps the virus bind to cells.
Once inside the body, the vaccine trains theto recognize the spike protein and target the coronavirus for destruction. Janssen Pharmaceuticals, the Johnson & Johnson company that developed the COVID-19 vaccine, used a similar strategy to develop its .
With FDA approval in hand, Johnson & Johnson can now ship about 4 million vaccine doses across the U.S., Dr. Richard Nettles, the vice president of U.S. medical affairs at Janssen Pharmaceuticals, told lawmakers earlier this month, the Times reported. Another 16 million doses should be ready by the end of March and 100 million by the end of June, although the company is currently far behind the number of doses pledged in its federal contract, according to the Times.
