Yeah . . no they weren't. A recent study in Japan showed they actually had a negative efficacy effect. IOW, they increased your odds of getting Covid (by 84%). The more shots, the greater the chances of getting again. Two studies one with a smaller group and one considered a mid sized study group comparing those with Covid shots and the control group. Consistently the vax didn't have a positive outcome. Of course this won't be released in MSm (who have been either bought off or afraid to speak out).
Also this has been my experience with my in-laws who did take the vaccine (more than once) they repeatedly got Covid over and over and were mad about it. But never said anything bad about the vaccine.
