Health, yes, my son was one of those kids who got the mumps even though he was vaccinated, also my daughter and even myself. I have had 2 daughters get chicken pox even though they were vaccinated. I will say, though, that the cases which they had were very minor, not the extremely painful, itchy, bed-ridden illnesses that one used to develop when one was sick with things like chicken pox, mumps, diptheria, measles, etc, and not to speak of the horrors of polio. Who would want their child to risk paralysis and lifelong disability just to avoid such a vaccine?
I am one of the kids whose mother used to take me around to all my friends when she heard they were sick with chicken pox. Back in those days there was no chicken pox vaccine (late 60s-70s), so everyone had to just get sick. I never ended up getting sick, so we always thought I just hadn’t had it. It wasn’t until I was 26 that I developed some kind of illness that had blister-like sores on my body, but it was a very mild case and nothing could be determined from a sample of the liquid in one of the blisters, so we still never knew if I had the chicken pox. Now when I was pregnant with my first, I was exposed to a child who had the chicken pox. I wasn’t worried for myself, but I was in my 9th month and developing chicken pox at that stage is dangerous for the newborn. She would only be protected if I had immunity myself. I had to go for a blood test to see if I had the antibodies in my blood, which I fortunately did, but I would have had to get a gamma glubulin shot within 4 days of the exposure or else it wouldn’t be effective if I wasn’t already immune.
Also, it’s not fair to say that people with children who are vaccinated won’t be affected because, being that the vaccines are only 80-90% effective, then if the child did in fact become even mildly sick, they would be contagious and they would not be able to go to daycare, school, etc, meaning the parent would have to take time off work, possibly lose wages/job, etc, plus the child would suffer unnecessarily.
