I'd like to know what the alternative your proposing is OP? Everyone just takes their chances? How long until you will decide it's safe? I'm not trying to be inflammatory, I'm genuinely asking.
Do you want everything to just reopen, which could allow covid to burn through the population for the next 10 years, killing millions? Or do you want everyone to remain in a state of semi lockdown for the next 10 years? And in 10 years will people still not want the vaccine because they don't know the effects (if any) at 20 years?
Yes, everyone is taking a calculated risk by getting a new vaccine. However the vaccine has been tweaked from other, longer term vaccines and the science we have today shows that it is very low risk compared to the very high risk of getting covid. Can we say it 100% safe - well no. But nothing in life is 100% safe. Is it ideal taking a new vaccine, well no and there is a small part of me that feels uneasy about it. But by allowing everyone else to have the vaccine and my sitting out, that would be allowing everyone else to take the risk and hope I get to enjoy the benefit of that. It's not fair. So I will take my small part of the collective risk because I cannot see a future where we continue to isolate for the next few years, or sacrifice millions to the raging virus.
