No truth in any of it unless you believe that hype. Not sure what nurses you talk to but all my nurse friends and the nurses I have advise to get the flu shots, just because it might not cover one strain of flu it will prevent another strain. Some people who don't want to get vaccinated believe that it causes autism, no correlation at all in that.
I would need proof measle vaccines are safe from a reliable source before I would give it too my kids if i had any.
As far as the flu vac. I don't need it.
