Johnson & Johnson’s single-dose COVID-19 vaccine is now the third vaccine approved by the US government for people aged 18 and above. The other two vaccines that are being administered to Americans are Pfizer/BioNTech’s and Moderna’s two-dose vaccines.
“We feel that each of these vaccines will be effective, will prevent hospitalization, deaths and should be used,” the acting commissioner of US FDA, Dr. Janet Woodcock said. Also Read: COVID-19 vaccine: Private hospitals in India subject to ceiling of Rs 250 per person per dose
In its global trial including 44,000 people, J&J’s vaccine was found to be 66% effective at preventing moderate-to-severe COVID-19 four weeks after inoculation. It was 100% effective in preventing hospitalization and death due to the virus.
There were very few serious side effects reported in the trial, which also offered preliminary evidence that the vaccine reduced asymptomatic infections. The vaccine is likely to gain popularity across the globe as it is single-dose and can be shipped and stored at normal refrigerator temperature.

J&J is testing a two-dose version of its vaccine, with results expected this summer, the report added. Also Read: When can we assume to have coronavirus under control?
