You question vaccines and yet you probably don't have any problem asking for antibiotic when you get flu, even though antibiotics don't work on viruses and only kills the healthy bacteria in your gut. Or, taking painkillers for headaches, even though one of its side effects for constant use is eventual hearing loss.

You question vaccines as if they are all the same, but don't question other medicinal products that are made in the exact same process as vaccines. And all medicines have some side effects nonetheless. Heck, almost anything you consume has side effects. As another person mentioned, we take medicines and they are approved because the benefits outweigh the risks. They are tested first for crying out loud.
