Giggle..... MMR stands for Measles, Mumps and Rubella. Hence the M....M...R
If the vaccine caused sterility, then half of our country would be sterile.
I would have posted the s/sx of measles, but would take up too much space and not many would read it, so I will provide a link to the Mayo Clinic
Measles - MayoClinic.com
Here is one for the Mumps.....this one is one that can easily cause sterility in male children
Mumps - MayoClinic.com
And Rubella
Rubella - MayoClinic.com
All 3 of these diseases are particularly dangerous to the pregnant woman and her unborn child if exposed. If she is exposed during pregnancy there is no treatment for her or her unborn child and can lead to VERY serious complication.
