Johnson & Johnson’s One-Shot COVID-19 Vaccine Effective, Safe: FDA Staff

Johnson & Johnson’s one-shot COVID-19 vaccine appeared safe and effective in trials, U.S. Food and Drug Administration (FDA) staff said in documents published on Wednesday, paving the way for its approval for emergency use.

The FDA’s panel of independent experts meets on Friday to decide whether to approve the shot. While it is not bound to follow the advice of its experts, the FDA did so when authorizing the Pfizer Inc and Moderna Inc vaccines.

J&J’s vaccine was 66% effective in preventing COVID-19 against multiple variants in a global trial involving nearly 44,000 people, the company said last month.

Its effectiveness varied from 72% in the United States to 66% in Latin America and 57% in South Africa, where a new variant has spread, though the vaccine was 85% effective overall in stopping severe cases of the disease.

The vaccine was effective in reducing the risk of COVID-19 and preventing PCR-test confirmed COVID-19 at least 14 days after vaccination, the FDA said in its briefing documents.

Three vaccine recipients had severe side effects in the trial, but the FDA said that its analysis did not raise any specific safety concerns that would preclude issuance of an emergency use authorization.

J&J had not previously released details of its clinical trial data beyond efficacy rates.

    1. Are you now the covid expert Chippy the Chump? I guess your old nickname Walter Mitty still holds true.

    2. The J & J vax is over 85% effective in keeping people from having to be hospitalized. And because it uses DNA which is much more protective, rather than RNA that Pfizer and Moderna use. It can be refrigerated for 3 months and several years in a regular freezer. Also no vaccine side affects like fatigue and sore arms. A single dose is a big positive also. It has it’s place perhaps in rural areas and younger demographics.
