Racedo, another thing to bare in mind is that it's largely going to be the older population (the same people whom we sacrificed our economy, jobs and livelihoods so they can live another 5 to 10 years) who will get the vaccine first. There will be plenty of time for further detailed studies about side effects. They need protection now, they'll get it and in another few years when we're approaching high risk ourselves all will be smoothed out.
I haven't perhaps worded this in the most respectful way possible but I hope my point is well made.
