But that's just it, we anecdotally know they're safe. There are tests we've run and the results are promising, but the true large scale inoculations haven't happened. All things point to these as being safe, but until it's more widely dispersed I don't think you can assert it as having the same safety as most modern inoculations. Cautious optimism isn't a bad thing, nor is hesitance to taking the vaccine. Its not really your place to convince them it is safe, that's for them to decide with the facts on hand. Provide them info on the tests, share whatever you have, but it's ok to not trust the speed at which these vaccines were made.
