Johnson & Johnson is the latest drug maker to make the case that an extra dose of its COVID-19 shot can help boost antibody levels. But that doesn't mean an extra dose of the J&J shot is a done deal.
Johnson & Johnson is the latest drug maker to make the case that an extra dose of its COVID-19 shot can help boost antibody levels—by at least nine times that of the levels recorded 28 days after initial vaccination.
On Wednesday, Dr. Mathai Mammen, global head of J&J’s Janssen Research & Development business, acknowledged that data in a news release, but also noted that “a booster dose of the Johnson & Johnson COVID-19 vaccine further increases antibody responses.” In a briefing announcing the plan for booster shots last week, federal health officials said they were concerned that the mRNA vaccines may not protect against severe disease in the future although experts say there is no data at this time that indicates this.
This is the highest daily average case count since Jan. 29 and the highest daily average of deaths since March 19, according to a New York Times tracker.
