Not the person who you're asking, but I'd personally prefer as many months (or years) as is needed. I have no idea if that's a few months or years and would love an answer grounded in science.

Could somebody just explain how scientists know decades-long effects after only months of research? I'm taking a vaccine, 100%, no matter what. I'm pro-vaccine. And even if we're unsure, what we know is the massive numbers of deaths we'll have without a vaccine.

I'm asking because I want more peace of mind about it.




A vaccine is "nothing" more than a way to tell your body what it needs to fight before it actually has to fight it. Whether that's via mRNA, DNA, dead virus, live virus, whatever. The method used to do that is less important than your body getting the message. If the vaccine causes decades-long effects, so will the virus itself. We're damned either way.


> If the vaccine causes decades-long effects, so will the virus itself. We're damned either way.

Any long-term effects from a vaccine seems unlikely to be as bad as the virus itself.

But still, is that really the answer? That there's no way to know about long-term effects until it's been out there for decades? I was kinda hoping there was an answer like "what we know from other vaccines is that any bad effects almost always show up in first few months -- never, or almost never, many years down the line."
