The issue with the Covid vaccine in particular is that it's been slammed through the process. Having it out in about a year is really fast compared to other vaccines which can take like 5-7 years of development and testing time and still fail to be approved for general use.

I think there's also a good question about the effectiveness rate, too - the flu vaccine has been developed for years and has only a 50% success rate at best, and it has to be readministered yearly because of viral mutations. If the scare mongering of "you can catch it again because it keeps mutating" is true, it means that the vaccine likely won't be as effective as they claim it is.
