Those who have had the company’s one-shot vaccination may need a booster. The FDA will review the data on Friday. Recent results from a nationwide clinical study suggest that those who got the Johnson & Johnson coronavirus vaccination may benefit from a booster injection provided by Moderna or Pfizer-BioNTech.

A fierce discussion about how and when to provide booster doses to the 15 million Americans who have received the single-dose vaccination may result from this discovery, as well as the FDA’s divided assessment of Johnson & Johnson’s case.

Some analysts predicted that the FDA would still approve the injections despite the new data on the boosters’ potency. The one-shot vaccination is less effective than the two-dose mRNA vaccines from Moderna and Pfizer-BioNTech.

The public may be anticipating the approvals, given the Biden administration’s drive for all-brand boosters.

A booster from Pfizer-BioNTech was approved last month, according to virologist John Moore of Weill Cornell Medicine. The Pfizer and Moderna vaccines are the most widely used in the US, with over 170 million individuals wholly vaccinated.  The FDA subsequently halted its use to examine uncommon blood clotting instances, reducing its popularity.

The date of a Johnson & Johnson vaccination booster authorization or any other brand is unknown. The FDA panel will only decide on Friday whether to allow a second Johnson & Johnson vaccine dosage, a situation the CDC’s vaccine advisory group will consider next week. If both agencies think an extra dosage should be given, individuals may ask for it next week.

It’s uncertain whether the FDA would approve the mix-and-match method. The plan will be debated but not voted on by the agency panel on Friday. If authorities agree on the technique, they will likely need to amend the authorization wording for the Moderna and Pfizer-BioNTech vaccines to enable usage in individuals who got the Johnson & Johnson vaccination.

The researchers discovered that individuals who had a Johnson & Johnson injection followed by a Moderna booster had 76-fold higher antibody levels in 15 days than those who received just a Johnson & Johnson shot. A Pfizer-BioNTech booster injection tripled antibody levels in J&J patients.

Scott Hensley, an immunologist at the University of Pennsylvania, found the findings convincing. He emphasized that the study only looked at antibody levels, which are not a good indicator of how effectively various vaccination combinations reduce Covid-19 infections and hospitalizations.

Some experts wonder how the federal government considers brand boosters, given the little evidence supplied by Johnson & Johnson and other businesses. In a major study sponsored by Johnson & Johnson, the FDA saw a possible increase in protection from a booster given two months after the initial injection. Some experts argue that the vaccination should have been two doses from the start.

The Johnson & Johnson vaccination has significant consequences for the shot’s future in the US, said Jason L. Schwartz, an associate professor of health policy at Yale School of Public Health. One dosage of J&J had a global effectiveness rate of 66% and a US efficacy rate of 74% against mild to severe Covid. Its global effectiveness against severe or critical illness was 85%.

Johnson & Johnson provided the findings of another large-scale study that started in November 2020, in which half of the participants received a second dosage two months later. Half got a placebo. They expected that individuals who got Johnson & Johnson’s injection would also need one, but additional data was required.
