I never used to get my flu shot. The first time I got it was during the swine flu outbreak that was hitting younger people harder. After that, the thing that really solidified me as an annual flu shot person was that I worked with kids every day and my work provided flu shots for free. I thought, "How selfish do I have to be to refuse a free shot on my lunch break that could protect these kids I work with from a potentially deadly disease?".

Over the years, I've taken a harder and harder line with anti-vaxxers. I have landed on the opinion that an otherwise healthy person that refuses to fully vaccinate themselves or their children is a selfish conspiratorial freeloader. I treat them nicely in person, but otherwise avoid them like the plagues they carry.
