The Johnson & Johnson coronavirus vaccine is effective against the highly contagious Delta variant, even eight months after inoculation, the company reported on Thursday — a finding that should reassure the 11 million Americans who have gotten the shot.
The vaccine showed a small drop in potency against the variant, compared with its effectiveness against the original virus, the company said. But the vaccine was more effective against the Delta variant than the Beta variant, first identified in South Africa — the pattern also seen with mRNA vaccines.
A dearth of information about the J.&J. vaccine had led many people to speculate that it might need to be supplemented with one dose of an mRNA vaccine. But at least for now, people who received the J.&J. vaccine should not need a booster, nor can they legally get one “unless they game the system, unless they pretend they’re vaccine-naïve and go and get an mRNA vaccine and essentially lie,” Dr. Moore said, “and I certainly don’t recommend people doing that.”
This is great to hear. I had been thinking about asking my doctor about getting an mRNA vaccine booster shot, especially after seeing these tweets:
Is there any data to support this recommendation? @VinGuptaMD I have had plenty of people ask about this scenario, and in principle it should work, but safety and efficacy data to support it would go a long way. https://twitter.com/VinGuptaMD/status/1409669269395173379
Since I’ve seen this advice be given multiple times privately:
If you received the 1-dose J&J, go and get 1-shot of Pfizer or Moderna as a “booster” when you’re able
Most I know who got J&J are doing it and are telling others the same — since two seems better than 1 re: delta
I continue to wear a mask, especially indoors, but this is good to hear as I try to pretend it’s ok to exist out in the world again.
