"These findings suggest that among people who have recovered from COVID-19, subsequent completion of the primary vaccination series reduced the risk of reinfection by approximately half."
I am really glad they are doing this because the anti-vaxxers are still touting their immunity as being more effective. The boosters were not included and we know their effectiveness wanes, so hopefully, their efficacy will stand the test of time as well. (it is not clear thus far without the stats to back it up. Plus, the newest variants are bypassing the immune system until the virus is already replicating, so our "armies" of antibodies are not able to do their thing.)
This is basically good news for for the shitgibbon Antivaxxers... but they will never listen to the science. The results show that a few AVers have opted to get the vaccine to relieve their long COVID and/or reduce their chances of almost dying a second time ... but I doubt, this site will be shut down any time soon.
