In reply to the discussion: Biden to announce 'historic partnership': Merck will help make Johnson & Johnson coronavirus vaccine [View all]tinrobot
(10,899 posts)42. Again, please stop spreading misinformation. It does not help.
If the J&J vaccine was not effective, it would not have been approved.
Here's a more in-depth analysis of the different ways the vaccines were tested:
https://www.statnews.com/2021/02/02/comparing-the-covid-19-vaccines-developed-by-pfizer-moderna-and-johnson-johnson/
But comparing the efficacy of those vaccines to the efficacy of Johnson & Johnsons is challenging because of differences in the designs of the Phase 3 clinical tests essentially the trials were testing for different outcomes. Pfizers and Modernas trials both tested for any symptomatic Covid infection. Pfizer started counting cases from seven days after receipt of the second dose of vaccine, while Moderna waited until day 14 to start counting cases.
J&J, by contrast, sought to determine whether one dose of its vaccine protected against moderate to severe Covid illness defined as a combination of a positive test and at least one symptom such as shortness of breath, beginning from 14 or 28 days after the single shot. (The company collected data for both.)
Because of the difference in the trials, making direct comparisons is a bit like comparing apples and oranges. Additionally, Pfizer and Modernas vaccines were tested before the emergence of troubling new variants in Britain, South Africa, and Brazil. Its not entirely clear how well they will work against these mutated viruses.
Different vaccines, tested differently in different places at different times. ALL of them provided excellent protection against severe disease and death. Spreading misinformation does not help get us through this.

OP
Only J&J has even been tested against variants. Your comparison is unfounded.

Great, but too bad they aren't producing more of the more effective vaccines

You're implying that this is the result of campaign contributions to Biden's campaign?

Unfair comparison. J&J's lower number includes variants. The others were tested pre-variant.

Profits. We live in a Global Corporate Oligarchy, never forget that simple fact.

Pfizer and Moderna's tests were before the variants. J&J's number includes South African and others

I was skeptical of the whole plan, having lots of experience with big companies,

I had seen where GSK/Sanofi were also going to try some of their other vaccine candidates

Thank you for fighting back against the lazy misinformation of some of the posters.
