Originally the Johnson and Johnson vaccine was found to have the highest efficacy rate over time compared to Pfizer and Moderna epically with the delta variant, but new research has shown that it has the lowest vaccine efficacy. Researchers are now saying that 2- 6 months after receiving the Johnson and Johnson vaccine people should receive a booster shot. The reason a booster shot is now being recommended is because after 6 months the Johnson and Johnson shot has been found to be much less effective in reducing serious illness or hospitalizations than the Pfizer and Moderna vaccines. With the J&J original one dose and booster shot there is 94% increase in effectiveness of the vaccine, and with just the original dose there is only a 68% effectiveness of the vaccine.
Researchers are calling for Johnson and Johnson to be rebranded as a two-dose vaccine rather than a one-dose vaccine with a booster shot. With the original dose and the booster shot, the Johnson and Johnson vaccine will be just as effective as both mRNA vaccines, but not have their fading protection, overall making it the most effective vaccine for protection against Covid-19. As of now one shot of the Johnson and Johnson vaccine is still considered full vaccination in the eyes of the CDC, but most likely that will soon be changed very soon. Although, people with either mRNA vaccine and its booster shot have a higher vaccine efficiency than two doses of J&J, the Pfizer and Moderna vaccines efficiency fade overtime and the J&J remains mostly the same making it the strongest vaccine.
Furthermore, the Johnson and Johnson vaccine is currently considered the weakest vaccine out of the three available vaccines. With a Johnson and Johnson booster shot, it will be considered the most effective vaccine because it does not fade in effectiveness overtime like the Pfizer and Moderna vaccines. Johnson and Johnson will most likely be changed to a two-does vaccine, since the FDA is recommending a second shot for anyone who got the one-dose. Sources:

I always knew that the J&J vaccine was a lot less effective than both moderna and pfizer, but I didn't realize by how much. It's nice to see that there is some hope for the future during times of covid.

Yeah J&J was thought to be the best vaccine to have against the delta variant , but with new research it has been shown that J&J's vaccine looses its efficiency over time, more so then Pfizer or Moderna.
DeleteHi Jess, I am astonished at how high the effectiveness jumps if a person gets their second shot for the J&J vaccine compared to only getting one. I know that some people were more content with getting the J&J vaccine because it was just only 1 shot, hopefully getting a second will not be an issue. I wonder if maybe over time the other brands of vaccines will have to get booster shots annually if the effectiveness fades over time?
ReplyDeleteYeah its was really crazy how high the efficiency rate of J&J becomes after getting a booster shot. I think it is a little funny that J&J was advertised as a one shot vaccine, but now will most likely become a two shot vaccine. And I think that all of the vaccines will require booster shots eventually.
DeleteI am surprised by the fact that the efficiency of the Pfizer and Moderna vaccines fade after some time, but I'm glad that Johnson and Johnson figured out a way to essentially make their vaccine the most effective out of the three - Tikweze Namadzunda
ReplyDeleteI was surprised by that as well, but I guess thats why Pfizer and Moderna are requiring booster shots now, to keep up the vaccine efficiency
DeleteJohnson and Johnson effectiveness doesn't fade at all overtime? Or is it just at a much slower rate than that of Moderna and Pfizer? Reading this makes me wish I had gotten the Johnson and Johnson just for the more elongated immunity period. I was also not aware that the effective rate of a single Johnson and Johnson shot was only 64% thats quite low!

ReplyDeleteGreat post. I also wonder why the effectiveness doesn't fade overtime after the second shot but does if you just get one. Does this mean it will be more effective than Moderna and Pfizer if you get two of the J&J? It's really good to see we now have some many options available to keep people protected.
