The highly contagious Delta variant has claimed a new victim worldwide: the effectivity of the Johnson and Johnson vaccine. A new study has led experts to urge recipients of the J&J vax to get a booster shot urgently. An advisory from the United States Food and Development Authority (US FDA)’s advisory committee shares their unanimous endorsement of the J&J booster’s emergency authorization.
This is on the heels of widespread concerns regarding the effectivity being less that of Moderna or Pfizer vaccines. Specifically, officials want those who got the shot to get a booster shot after two months.
“J&J is a very good vaccine. I also believe it’s probably a two-shot vaccine,” Brown University School of Public Health’s dean, Dr. Ashish Jha, told CNN. “It’s really urgent that people get that second shot pretty quickly.”
Recently, a study that hasn’t been peer-reviewed just yet was published. It analyzed 620,000 military veterans who were J&J vaccine recipients this year. Effective protection fell sharply from 88 percent in March all the way down to a mere 3 percent in August.
While other vaccines also saw their vaccine protection fall, Moderna went from 92 percent to 64 percent. Pfizer was slashed by almost half: 91 percent to 50 percent. This all happened within the same time period.
“I think anybody who’s gotten one dose of the Johnson & Johnson vaccine can benefit,” FDA’s Vaccines and Related Biological Products Advisory Committee member Dr. Paul Offit told CNN, “from a second dose of a Johnson & Johnson vaccine.”
If rushing to get emergency approval had not been a factor, the Johnson & Johnson vaccine would likely have been two-shot, he added.
Recently, the FDA panel also unanimously approved a half-dose Moderna booster shot for at-risk Americans. A Pfizer booster for the same at-risk groups has also been approved.
