The MMR vaccination is amazing. It is one of the most effective vaccines we have. Thanks to the vaccine measles is no longer endemic in the US. If this many people think this of the MMR vaccine we are doomed.
School vaccination mandates are essential for controlling measles in particular. The herd immunity threshold for measles is over ~95%. We can't afford much margin for reduced MMR vaccination. Measles is far too transmissible. Outbreaks occur when the vaccination rate falls below the threshold.
