One downside of badgering people into vaccinations is that they will associate any negative experience in the days following with the injection and blame it. There was a female popular singer who got a lot of attention recently because a friend's cousin (or a cousin's friend?) got the vaccination and two weeks later had something go wrong with his testicles. The best response I saw was a friend who passed on a tweet "My cousin's friend got the vaccine, and two weeks later he gotten bitten by a moose. Do the research, people."
It is easy to sneer, but this happens all the time even with free choices. The brain seeks answers, and will settle on a bad one that fits its schema. That the explanation does not explain does not bother many people. It is the lack of explanation that is unendurable. They told me I had to get the shot in order to visit my grandmother and said it was safe, but now my immune system is worse and I get every cold and flu that comes along. The hard part is that these explanations will often never go away, remaining impervious to all reason.
I heard these all the time when taking social histories from patients or families about how this illness started. He was doing fine, had a job and was going to school part-time, and he moved in with this girl. She was a nice enough girl but she broke the relationship off and he went into a tailspin. He started talking psychotic and taking drugs and he's never been the same. He still talks about her. What is much more likely is that he was getting psychotic and taking more drugs, so the girl broke the relationship off. Cart/horse. Especially with our children, we make up these explanations for what went wrong based on the time association rather than a logical association.
Sometimes they are quite true. A serious head injury can explain just about anything. When I first started reading CS Lewis I marveled that he was doing something like algebraic proofs with ideas instead of shapes and graphs. I was stunned to later learn that he was not good at math. His mother took a math degree and taught it. He occasionally handled scientific concepts in his examples that were largely founded on mathematical principles. It seemed impossible. Only later did I learn that when he was at the school run by a certifiable and violent headmaster, he had that person as his maths instructor. Students were beaten if they got the answer wrong. They were also beaten if they got the answer right. That could interfere with learning.
Time association has largely driven the vaccine-autism fables. During the years when a child begins to interact with the world enough to display that something is wrong, he also gets lots of vaccinations. Such symptoms do not show up with bang, usually. It's not like a fever or neck pain where it was not there yesterday, but unquestionably here today. But once the idea is planted that this odd behavior in your child might be caused by vaccines, many parental minds are going to leap to "Hey, yeah, he did get a vaccine six weeks ago."
I think I have post brewing about Infection Control Nurses and the wheedling, badgering, suggesting, and insisting they do as a normal part of their job, trying to get employees to accept flu shots, or environmental services to ramp up its surface cleaning, or other infection prevention interventions. (Or maybe not. The summary is pretty easy. 1. Mandating an intervention is part of that continuum, not some entirely separate thing out of the blue. We have "forced" families to comply with various levels of health precautions for years. 2. Sometimes the professionals can be wrong, as can the nutritionists or psychiatrists or anyone else in the system. Just as in any profession. But mostly, 90%+ of the resistance and refusal they get is based on the same dumb-ass stuff they hear every year, of people claiming the flu shot always gives them the flu, or droplet precautions can be ignored if you are just poking your head into the patient's room for a second to tell him his visitors are here or whatever.) But the key takeaway is that the more you do this, the more resentful people are going to blame any subsequent thing that goes wrong on the hospital/school/Big Pharma, whatever.
Thus, I am big on avoiding that as much as possible. Over time it builds distrust of the whole system even when it is completely undeserved, because people don't like some explanations. Yet I also know that people cannot always be persuaded, and sometimes you have to put the hammer down. That's not just hospitals and health, it's your profession too.
