Like all medical procedures, devices, and pharmaceuticals, vaccines are not perfect – there are rare vaccine adverse events. What matters is that the benefits, not only medically but also economically, outweigh any risks. As far ask I know, no perfect medical procedures, devices, or pharmaceuticals, none, that are perfectly safe or perfectly effective. Sometimes the ratio is small.
For example, there are chemotherapy drugs that only add a few months to a patient’s life, usually with substantial side effects to the medication. Yet, if you ask a patient whether it was worth it, to spend just a few extra months with their children and loved ones, the value becomes nearly incalculable.
But mostly, the FDA and other regulatory agencies demand that new products and procedures must meet or exceed the safety, and meet or exceed the financial and health benefits of currently acceptable versions. Actually, the FDA examines a lot more than that.
They check the packaging, shelf life, instructions, manufacturing practices, and so much more, it would take a book to explain it (and there probably are several). It may not be a perfect process, but it’s better than what we had 100 years ago, and it continues to improve every single day. People tend towards a form of confirmation bias where they remember where a drug may have been found to be dangerous (the best example is Vioxx).
But they forget about the millions of medications and devices that save lives or measurably improve the standard of living.
