About Johnson and Johnson
The Janssen COVID-19 vaccine, also known as the Johnson & Johnson COVID-19 vaccine, is a COVID-19 vaccine produced by Janssen Vaccines in Leiden, Netherlands. Its Belgian parent firm is Janssen Pharmaceuticals, a Johnson & Johnson affiliate. It is one of the first vaccines available on the market with a one-shot regimen.
Johnson and Johnson WHO status
The vaccine’s Phase III clinical trials began in June 2020, with around 43,000 patients participating. On January 29, 2021, Janssen announced that the vaccine was 66 percent effective in preventing symptomatic COVID-19 in a one-dose regimen.
In addition, it was 85 percent effective in preventing severe COVID-19 and 100 percent effective in saving the life of any patient as soon as 28 days after vaccination. Since WHO requires just 50 percent efficacy to be approved, Johnson and Johnson fit the bill.
As soon as final trials were over, WHO had given this vaccine the green light for emergency use all over the USA and other countries.
Johnson and Johnson EMA status
It’s a viral vector vaccine based on a human adenovirus that’s been engineered to include the gene for the SARS-CoV-2 virus’s spike protein, which produces COVID-19. The vaccination just takes one dosage and does not require freezing.
The US Food and Drug Administration has given the vaccine an emergency use authorization, while the European Medicines Agency has given it a conditional marketing authorization.
