It's entirely acceptable on a society level if the numbers are low enough. If 1 in a billion die from a vaccine, do you approve it? There's probably at least one person who died in an accident from an airbag that otherwise wouldn't have without an airbag. Do we remove airbags despite them being statistically safer? This kind of "Zero Allowable Risk" attitude is quite frankly technophobic.
None of those examples you gave work here. The numbers that die from vaccines are much lower than the numbers that die without them, and it's a problem where a decision must be made. And nobody chooses or is convinced to be in a car accident. Shit just happens.
The people who get LASIK chose to do it either because they saw an advertisement or someone convinced them to do it. Nobody's life is saved by LASIK, and people can live a perfectly good life without it. They can wear glasses or contact lenses, or wait until someone comes up with a safe alternative to LASIK.
Read through some of the stories [1] from people who have had complications so you see that this isn't a minor statistic that can be easily ignored. Peoples lives are actually being ruined.
