It is a highly personal choice when it comes to vaccines. When I retired from the military I decided that I would no longer get the seasonal flu shots; 26 of them was enough for me. I only got/get "sick" about once every three years for about 3-4 days. I will not be receiving any vaccinations unless required by law. I HAD (NYS law) to get an MMR shot to attend college because I could not prove I had two of them in my life of 47 years. Either way, no voluntary vaccinations for me.
