> It can cause liver injury in a really small amount of cases, which should self correct. Great, now multiply the usage expectations by 1000 and include that people in that pool will have each possible additional liver related factor. (Now "should" being 99% isn't even good enough.) When we analyze how safe a vaccine is, a few dozen people who might have very specific health problems having potentially fatal reactions is a problem if we can't preidentify that group. When we allow a contagion to spread to endemic and therefore eventually encompass the entire population a treatment needs a closely proportional safety level to a vaccine and will eventually need to be far safer than any long acting vaccines. If 10% of the population are going to take any treatment much more active than placebo, it has to be safer than most OTC medications for it not to kill a hundred times more people than giving everyone the least safe vaccine.
