USA govt info on Different COVID-19 Vaccines
“Pfitzer
Information on how well the vaccine works
• Based on evidence from clinical trials, the Pfizer-BioNTech vaccine was 95% effective at preventing laboratory-confirmed COVID-19 illness in people without evidence of previous infection.
Moderna
Information on how well the vaccine works
• Based on evidence from clinical trials, the Moderna vaccine was 94.1% effective at preventing laboratory-confirmed COVID-19 illness in people who received two doses who had no evidence of being previously infected.
J&J
Information on how well the vaccine works
• The J&J/Janssen vaccine was 66.3% effective in clinical trials (efficacy) at preventing laboratory-confirmed COVID-19 illness in people who had no evidence of prior infection 2 weeks after receiving the vaccine.
• The vaccine had high efficacy at preventing hospitalization and death in people who did get sick. No one who got COVID-19 at least 4 weeks after receiving the J&J/Janssen vaccine had to be hospitalized.
• Early evidence suggests that the J&J/Janssen vaccine might provide protection against asymptomatic infection, which is when a person is infected by the virus that causes COVID-19 but does not get sick.”

note that I am not suggesting anyone try to cherry pick which vaccine they receive. I recommend accepting whichever one is available to you.
note that the J&J results are based on a much shorter timeframe,
just 2 weeks after first shot of the vaccination. There is no second shot for J&J and immunity continues to increase up to 4 weeks after the shot
The Pfitzer results were based on 4 weeks after the first shot, to develop immunity
Moderna results were based on 6 weeks after the first shot, to develop immunity…
