I'm confused by this too. The argument I hear thrown around is that we are somehow ruining herd immunity for people who need to rely on it because they can't have vaxes for medical reasons. So basically if immuno-compromised Johnny sits next to Religious exemption Suzie in 3rd grade, the world is going to come to an end - for Johnny at the very least?
However, the stats I see (at least with regards to school enrollment) is that non-medical opt-outs on vaxes are far less than 1% of the children in school and total unvaxed rates are only around 2%. If you see the school as the herd, we aren't statistically significant enough to cause outbreaks. If you consider all the people your kid comes in contact with though, at the grocery store, the park, the mall, the movie theater, there's a much larger portion of the herd - adults that have waning immunity or were undervaccinated - that leaves you unprotected and is a much more likely source of infection, isn't that right?
There was a study done after Arkansas added a philosophical exemption to see if the number of people taking an exemption increased after the law changed. It did, quite a bit, by between 15% and 50% each year for 3 years. Study
here . Oddly, they note that incidence of VPDs actually
decreased during this time. In fact if you look at the incidence rates from the AR health department (
http://www.healthyarkansas.com/data/...le_disease.pdf) Pertussis rates dropped quite a bit in the year vaccine exemptions in schools rose the most. Not saying that proves anything, just suggesting that voluntary non-vaccination does not at this point seem to be having a significant effect on overall disease rates in a community even when there is a pretty big rise in our numbers. Maybe not enough time has gone by to see the effects though.
Forgoing vaccines is not a popular choice and never will be, unless some extremely compelling evidence comes out that we are doing more harm than good as a society by vaccinating children, so attacking those of us who make this decision just seems like a waste of energy, even if you are someone with an immune compromised child. Seems like your ire would be better directed at parents who never keep their kids home when they are ill. Aren't the odds a lot higher that a vaxed kid whose parent doesn't want to take time off work will end up infecting somebody with a delicate immune system with something like strep throat and having that lead to severe complications?
Why berate a parent who is just trying to figure out the best solution to a complex issue? After all, it is in part all the bullying and screaming and arm waving that keeps us from being able to find the answers to the questions that might set our minds at ease and keeps a lot of us in a state of doubt about their safety and efficacy.
I for one really want to believe that vaccines work and are safe, but I have a lot of questions that no one seems to want to answer.
Please, please, please correct me if I am misinterpreting anything.
