It's important to point out that not everybody should be vaccinated - in a few cases, such as where your immune system is compromised or you have severe allergies, it's not worth the risk. That sounds like your case, but bear in mind that you'll be relying on herd immunity, so you should be encouraging people to get vaccinated. If your health is that bad, I doubt you'll be very happy if you do catch something like chickenpox or whooping cough.
