Health: You hold vaccines are more dangerous than the disease that they work against!
So YOU DO the Study.
Health, you are not making any sense.
How can ANYONE do a randomized double blind study -where half the kids would get a vaccine and
half would get placebo?
The AntiVaxxers would not let their children participate because they believe vaccines are too dangerous.
The ProVaxxers would not let their children participate because they believe being Unvaccinated is too dangerous.
