I hope all those that are worried about putting a vaccine in their body don't eat chicken or any other mass produced meat. Most cattle is poked and prodded with various antibiotics and vaccines these days, GM growth supplements etc... Even your veggies are probably assisted by lab altered gene splicing and such for pest and weed control, climatic resistance etc.... You are best not eating anything, better still hold your breath if you live near a farm or city, the stuff floating around in the atmosphere might affect you over the long term.....
