The OP is not wrong to be concerned about a vaccine potentially being rushed through.
Vaccine damage is real, does happen, even with vaccines which have been trialled and tested more thoroughly, and with far more longevity follow up studies than this potential vaccine will have.
The swine flu vaccine situation hardly covered itself with glory, if people want a recent example, and then of course there are more historical examples too.
It isn’t wrong to question this. It doesn’t make the OP stupid, unable to process information, an anti vaxxer, or anything else. It just means the OP is thinking about the situation, and wanting to talk it through.
It is a concerning situation. We are all facing an uncertain future.
Wrt to OP’s concern (I think it was the OP, apologies if it was another poster) about only hearing about the deaths, and not hearing any other side - I read this as meaning we are not hearing any other information which could put the death rate into context. 15000 deaths is obviously horrible, and a scale like we haven’t seen in this country before. But 15000 deaths out of how many people who have had the virus in total? We simply don’t know. 15000 deaths out of 60,000 people who contracted the virus is a far worse death rate than out of 600,000 people, which in turn is worse than out of 6,000,000 people. And we simple don’t know, and cannot know.
This means we cannot have full disclosure of any risk:benefit ratio of the vaccine, when it does arrive.
It’s a concerning situation.
