Get my second in 30 days. It was through the Fire Dept. So far, zero effects. BUUUUUUUUUUUUUT.....When I walked in, I asked a JFRD bud if he TRIPLE dog dared me to run in circles on the floor, like Curly of the Three Stooges, right after I got my shot. He said he did not want us to be on the local news! LOL
