I am eagerly awaiting my vaccine, however we are all alpha/beta testers. A real concern is about safety of those vaccines as typically they require ~3 years of testing and a single fatality aborts their use. Would you give alpha version to people you love? Why is this concern downplayed? I understand statistics but we have no clue what could go wrong in an early version of a new technology and no data on long-term im…
I wouldn't say alpha testers and probably not even beta testers. They did clinical trials for these vaccines in 2020 with tens of thousands of volunteers long before these were approved by the FDA and other regulatory bodies! And as I will explain in a second, these clinical trial patients were actually more like beta testers than alpha testers.
The short version is that mRNA vaccines have been around for ~40 years with pretty well identified side-effects and risk profiles. The use of an mRNA vaccine for COVID is a new application of existing technology. One comparison might be the flu vaccine. You get an annual flu vaccine that has Another comparison for the HN crowd might be that it's more like the difference between the iOS 14 and iOS 15. That is, the vast majority of the OS hasn't changed that much and has been thoroughly tested, and most of the testing is focused on the new features/major changes. You don't need 5 years of testing to uncover every bug in iOS 15 -- one year should be plenty to find the major offenders. When Apple releases iOS 15, they do so basically saying "based on our testing, this is stable enough to be a benefit to >99% of our users and we think you would be best served by upgrading from iOS 14 to iOS 15." They are not promising no bugs at all, but rather saying that the major vulnerabilities and side effects have been patched/mitigated. Similarly, the pharmaceutical companies and the regulatory bodies like the FDA are suggesting "this is safe and effective, with the risk of side effects A, B, C, D..."
