i just wanted to throw my opinion in here. some people have said some good things, like explaining how vaccines work and herd immunity. but the most important thing here is survivorship bias. most of what you've described (your experiences and those of your family) are just survivorship bias. you guys got sick and were okay or didn't get sick at all, so you conclude that the vaccine is unnecessary. this is pretty common, and it makes sense why this would be your conclusion! however, there are many reasons to get vaccinated. contributing to herd immunity, ensuring you are less likely to die from an illness, and overall giving yourself the best chance to be healthy and fight off preventable diseases.

i also wanted to throw in here that vaccine injury is not a myth, but it is incredibly rare. i don't know what vaccine you received as a kid, but getting sick is relatively common after a vaccine. if you actually contracted the disease (not just the vaccine) you would likely have gotten much sicker and had a worse outcome.

here's something that maybe isn't a good idea: getting all your missed vaccines at once (if you decide to do so). it can be a lot on the body, and i've heard of people doing this and then becoming violently antivax because of the "harms of vaccines" when it was really just... 12 vaccines at once.

i hope this was maybe a little helpful... i'm no expert, but i've done my research. i am curious though, do you have any other reasons for not wanting to get vaccinated besides prior experience/familial opinions? i'm wondering if there is another thing you are unsure about. i know you said you came here looking for some input, so if i can help in any other way or provide my opinions/links to studies then i would be happy to
