I simply can't see any good reason why someone would not want to get vaccinated. My wife and I and everyone we know has been and no one had any bad side effects...a few mild aches and pains in a few cases.
Better safe than sorry and as I have told others we have all been vaccinted before in the past for Polio and other childhood diseases and 99.9% of us are still standing.
I am a former eye doctor-Optometrist- and as such have had education seminars on related subjects, and these fears about side problems are unfounded. I'm not going to address the 'political' and 'social' beliefs on the 'anti'vaccers' because imho they are even more silly.
