News like these create an unnecessary loss of confidence in vaccines because the fact is that, in a Randomzied Control Trial (RCT)
, some volunteers are given potent vaccines while others are merely given placebo
(something that looks like vaccine but is as good as water). It’s important to do this to truly test the efficacy of a vaccine (same logic applies to medicine trials too). Now when a trial is blind (which most trials for vaccines are), the volunteers don’t know if they got the real vaccine or the placebo! And that means any volunteer can always catch the infection! It was a “trial” for a reason!
OK, tell me something - once you get vaccinated, would you still need to wear a mask? Could you still spread Covid to others?
The answer is yes to both and to understand how you could still infect others (if they are not vaccinated), check out the below brilliant Twitter thread.
