Both Pfizer and Moderna vaccines have shown higher efficacy rates as compared to Johnson & Johnson but experts have advised against direct comparison and say all three provide strong protection
An advisory panel of the Centers for Disease Control and Prevention (CDC) voted on February 28 to recommend Johnson & Johnson’s coronavirus shot for Americans 18 years and older, clearing the way for vaccinations to begin this week. The vaccine is the third to be approved for use in the US, and the first that requires only one shot. The nation’s leading infectious disease expert, Dr Anthony Fauci, has now encouraged Americans to accept any of the three “highly efficacious” shots available to them and not get selective about them by picking one over the other.
The director of the National Institute of Allergy (NIAID), and chief medical adviser in the Joe Biden administration emphasized that he would take any of the three authorized vaccines in the US because all provide strong protection against severe coronavirus. “These are three highly efficacious vaccines. I can tell you I have been fully vaccinated with one that was available. It was the Moderna. If I were not vaccinated now and I had a choice of getting a J&J vaccine now or waiting for another vaccine, I would take whatever vaccine would be available to me as quickly as possible…we want to get as many people vaccinated as quickly and expeditiously as possible,” Dr Fauci told CNN’s ‘State of the Union.’

Both the Pfizer and Moderna Covid-19 vaccines, which were earlier authorized for emergency use in the US, have shown higher efficacy rates in clinical trials that used two doses when compared to the Johnson & Johnson shot.
A review by the US Food and Drug Administration (FDA) suggests that Johnson & Johnson’s vaccine efficacy against moderate to severe/critical coronavirus was 66.9% at least 14 days after the single-dose vaccination and 66.1% when considering cases occurring at least 28 days after vaccination. Additionally, the vaccine was approximately 77% effective in preventing severe/critical coronavirus occurring at least 14 days after vaccination and 85% effective in preventing severe/critical Covid-19 occurring at least 28 days after vaccination. Phase 3 results of Moderna show that vaccine efficacy against Covid-19 was 94.1%. The Pfizer vaccine was found to be 94.8% effective after the second dose.
However, health experts, including Dr Fauci, have urged Americans not to worry. Scientists explained that direct comparison is difficult because no trials compared efficacy. Brinkwire Brief News.
