Well it's generally accepted that all the vaccines are safe within a degree of reason. You're the one who believes that that safety has yet to be proven, though, if your only criticism is that they're new, and they haven't stood the test of time, then that's impossible to prove, you could literally say that about any drug created after 1930 (Ivermectin included).
But what I'm asking is, there's many types of covid vaccines, some that are mrna, and some that use a more traditional method of vaccination, the same method that we see in vaccines you probably received when you were a baby, they just change the type of virus that your body will make antibodies for. But it seems you're not interested in any of the different types of covid vaccine for no other reason than they're all covid vaccines.
