> 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."
