Question #1: Flu Vaccine and Herd Immunity ()[edit]

In the past I didn't get a flu vaccine. I get pretty nervous around needles and have fainted in the past when having blood drawn for testing, so I didn't want to put myself in that position. I also thought that I'm only affecting myself by not getting the vaccine each year. My question is, is there a herd immunity factor to flu vaccines?
– Thanks, Eyal Sion
