Remember that there is NO COVID-19 vaccine "approved for normal use". All of them ONLY have "Emergency Use Authorization" due to the severity of this terrible pandemic.
So you are seeing something a bit unprecedented because of the fast-track nature to allow the mass vaccinations in order to try to get a handle on this virus since lockdowns and other measures like mask-wearing, are obviously not working well.
Over time, there will be MUCH "tweaking" of all of them and the trials are continuing. In fact as I understand, they are all also working on alterations and/or boosters to deal with the variants. That is what happens yearly with the flu vaccine.
Each year they look at which variants of Influenza are circulating in Asia/Australia and then try to estimate/guess which ones may end up being prevalent here and will select those to come up with a vaccine to use in the annual flu shot. In many cases, the guesses "fail".
For example as reported at the beginning of 2020, CDC released their report on the 2019 flu vaccine effectiveness as reported here -

CDC Releases Interim Flu Vaccine Effectiveness Report
February 26, 2020 10:01 am Chris Crawford -- According to a Feb. 21 CDC Morbidity and Mortality Weekly Report, the current influenza vaccine has been 45% effective overall against 2019-2020 seasonal influenza A and B viruses.
Specifically, the flu vaccine has been 50% effective against influenza B/Victoria viruses and 37% effective against influenza A(H1N1)pdm09.
According to former AAFP Vaccine Science Fellow John Epling, M.D., M.S.Ed., of Roanoke, Va., that means the vaccine is about as effective as it typically is in a season when it offers a decent match to circulating influenza antigens.
"The meaning of the effectiveness number gets misinterpreted frequently," he told AAFP News. "While we would all want an even more effective vaccine, it remains the best way we have to prevent flu and its complications."

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 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.
