I know people personally who have spent many years working on this type of thing (studying virus, vaccines etc. in a university), so I am more inclined to trust them rather than some dude on the internet.

Literally hundreds of thousands of people have died already from this virus in the USA - so I think a vaccine is worth a try (note millions of people have already had these vaccines, so I think we would know by now if it was killing people).

Anyway, I'll be getting a vaccine when it's available to me and I'll let you know if it gives me any problems!
