I find it hard to talk to both sides as I'm a fence sitter (actually probably have more limbs on the pro-vax side). My DH and his family are firm pro and my mum is firm anti, although she started pro but after I had an extreme reaction as a child (hospitalisation not just flu symptoms, I have a hereditary contributed reaction to many medications) she stopped. I chose to be vaxxed as an adult and I will probably vax my children but I am scared in case their health is threatened by a) my choice to vax or b) a choice not to (and the diseases they will be susceptible to). BASICALLY its human nature to defend anything you feel strongly about so its hard to talk to any opposite believers!
