Yes, they did. There is always going to be a caveat to using any medicine when it “launches” as rare side effects that just can’t be picked up in clinical trials are going to be suddenly noticed when the number of people receiving the treatment goes up.I can understand people being a bit wary of the first iteration of the vaccine in fairness. Didn't one of the swine flu vaccines trigger narcolepsy in a few cases, and get withdrawn?
There is going to be some serious freaking out about this vaccine when it comes online because clinical trials will be performed on the range of thousands but we are looking to effectively treat billions of people. Even if there is only 1 in a million chance of something serious happening, that’s still going to be a lot of serious side effects worldwide. I suppose the goal will be to hopefully figure out who’s susceptible, why, and treat accordingly (ie with another drug to counteract the effects if possible) or not depending on what it is.
