Andy slavitt johnson and johnson12/14/2023 If a vaccine prevented asymptomatic infection, it might help reduce opportunities to transmit the disease - not just keep the vaccinated from getting sick. More research is needed, but the FDA analysis also hinted that the J&J vaccine may help prevent asymptomatic infections.Ī January study from the CDC showed that most coronavirus cases are spread by people without symptoms. For example, in the first week of the Pfizer vaccine rollout, there were only 29 cases out of 1.9 million doses administered, according to the US Centers for Disease Control and Prevention. There have been a small number of severe allergic reactions with the Moderna and Pfizer/BioNTech vaccines. Overall, non-fatal serious adverse events were infrequent, according to the FDA’s analysis, and there were no reported cases of anaphylaxis following vaccination in the trial. The vaccine comes with few side effects, most of which are mild, including pain at the injection site, headache, fatigue and muscle pain. Paul Offit, a vaccine adviser to the FDA, told CNN’s Wolf Blitzer on Friday. “One dose will keep you out of the hospital, keep you out of the intensive care unit, and keep you out of the morgue,” Dr. In the US, it is considered 72% effective, and offered 86% protection against severe forms of the disease. Globally, it was 66.1% effective against moderate to severe/critical Covid-19 at least four weeks after vaccination, according to an FDA analysis. The vaccine was tested in more than 44,000 people in the US, South Africa and Latin America. “The Janssen vaccine candidate checks nearly all the boxes.” “We’d want to see a reasonable duration of efficacy and protection. Greg Poland, head of the Mayo Clinic’s Vaccine Research Group, said Friday. “We need a vaccine that can be quickly mass produced,” Dr. The vaccine is authorized for people ages 18 and older. It’s a single dose, and it doesn’t require special storage. The vaccine, made by Janssen, J&J’s vaccine arm, is safe and effective, and it’s considered flexible. “A third safe and effective vaccine is very welcome news,” Andy Slavitt, the White House’s senior for Covid Response, tweeted on Friday. With more than 28.4 million confirmed Covid-19 cases in the US and nearly 511,000 reported deaths since the start of the pandemic, and while the demand for vaccine still far exceeds supply, these vaccines can’t come soon enough. It is the first single dose Covid-19 vaccine available in the US, and is one that “checks nearly all the boxes.” (CNN) - The US Food and Drug Administration authorized Johnson & Johnson’s Covid-19 vaccine Saturday.
