6 patients presenting allergies from 170,000 doses distributed and an immediate recall is a non-issue pippy. They were quick to act and nobody was seriously injured. Small instances like this don't in my opinion invalidate the science of vaccines, it comes down to intrinsic human error more than anything.
What validates a vaccine as worth while is when it saves more lives than it costs lives in making the expected outcome more favorable statistically than the chances of dying from the original vaccine, for example if 1/100,000 will catch a disease and 1/1,000,000 will die but you can take a vaccine that has 1/1,000,000 chance of getting minor side effects and 1/10,000,000 chance of death then you have still reduced the overall number of fatalities by a beneficial amount - ultimately making the vaccine worthwhile.
If there is a risk of losing a pregnancy while taking a vaccine then maybe you should avoid the vaccine instead and try hide behind herd immunity.
