I too would like to read this alleged letter from the gedolim. I find it hard to believe that a gadol would sign to that. But i am open to seeing this letter and to reading the gedolim’s reasoning.
I am a staunch supporter of vaccinating children. I am so glad that my children are in yeshivos and bais yaakov’s with a nurse from the BOE, who must have documentation about each childs vaccinations.
During my last pregnancy i found out that i was not immune to Rubella. I got the MMR after my baby was born. Pregnant women are usually notified and advised by their OB’s to get specific vaccines if they are no longer immune or if they are vulnerable to a disease/virus going around like H1N1, Whooping cough, measles, etc.. And why were we instructed to get these additional vaccines? Because of some selfish individuals who will not vaccinate their children and spread the measles, whooping cough, etc..
One who is vaccinated has the ability to fight off that disease/virus’; this doesn’t mean they don’t get it, it means that its much milder and usually not as extreme as one who is not vaccinated.
