I've never had the flu or a flu shot. If vaccines were safe there wouldn't be a huge Federal fund for people with vaccine injuries (to protect the drug companies). Almost all my ancestors lived long lives without antibiotics, vaccines and very few doctors. One of Grandfather's uncles that lived on a ranch in Gonzales County died around age 50 but I'm pretty sure the Injuns got him. All of my Grandparents were born at home and none of them got a HEP B vaccine on the day they were born.
