The U.S. drug regulator has cleared the nation’s third coronavirus vaccine, giving emergency approval to the injection by Johnson & Johnson.
The Food and Drug Administration said on Saturday it had given the green light for the inoculation of J&J, which will be the first to involve just one stroke. The company said it was ready to ship 4m doses immediately, although that was less than the 10m the U.S. government was hoping for, thanks to manufacturing issues that marred the deployment.
Janet Woodcock, acting chief of the FDA, said in a statement: “The authorization of this vaccine expands the availability of vaccines, the best method of medical prevention for Covid-19, to help us in the fight against this pandemic, who claimed more than half a million people live in the United States. “
Joe Biden, the US President, issued his own statement saying, “This is exciting news for all Americans and an encouraging development in our efforts to end the crisis.”
The United States has been vaccinating people against Covid-19 for weeks using inoculations produced by BioNTech / Pfizer and Moderna, and has so far vaccinated 72.8 million people.
The J&J vaccine uses a different technology known as a viral vector, which involves injecting recipients with a modified version of a harmless virus to trigger an immune response.
Medical trials in the United States have shown the vaccine to be 86% effective in preventing serious or critical illness, while those in South Africa, where the most transmissible 501. V2 variant of the disease is prevalent, have shown an efficiency of 82%.
However, the vaccine was less effective in preventing moderate to severe disease, showing 72% effectiveness in the United States and 64% in South Africa.
Trials did not show any unexpected side effects, with recipients mainly complaining of injection site pain, headache, and fatigue, as has been reported with Moderna and BioNTech / Pfizer vaccines.
Saturday’s decision came 24 hours after an independent panel of experts recommended J & J’s vaccine for clearance, in line with the FDA ruling that it was both safe and effective.
This week, the death toll from coronaviruses in the United States topped 500,000 – by far the highest death toll in the world in absolute terms and more than the number of Americans who died during World War II, the United States’ War. Korea and the Vietnam War combined.
