They only need to be certain that the risk of the vaccine for the individual is lower than the risk of Covid for that same person.

In what way do you think millions of doctors, disease experts, and drug researchers have gotten that wrong? They have evidence that Covid is worse, but where is evidence to the contrary?

> I'm very surprised decades of science fiction litterature isn't enough to make people think twice.

Isn't it arrogant to assume that all the experts on vaccines are less informed or less cautious than you are, just because you've read sci-fi?

They didn't just think twice. They've done decades of research and testing, and they've closely monitored safety at every stage of rollout.

i don't know a lot of doctor that advocate for the benefit of a covid vaccine for young kids. when they do it's usually in the hope of herd immunity, which seems disproved by the variants cases in countries with hugh vaccination rate.

in general i would also be very skeptical of "scientific consensus" related by the media when you see how much bad press some doctor got for criticising public health politics (even when proved right later on).
