I was exposed to the live virus FIVE different times.
I’m sure the new NHS will was THOUSANDS of taxpayer dollars ensuring I’m up to date on every vaccine regardless of whether or not I actually get immune to anything.
After all, it’s not THEIR money they’re spending, it’s ours.
If your immune system is incapable of mounting a B-cell (antibody producing cell) response to a challenge with a pathogen (whether the pathogen is alive and virulent, an avirulent strain, or a killed pathogen), then your chance of serious, life-threatening infection if you are ever exposed to one of those pathogens is quite high.
The best protection for people with sub-optimal immune systems is for everyone around them to be vaccinated, and to never encounter an unvaccinated person. Those diseases can kill an immune-deficient person quite quickly.
I’ve had 3 kids all of whom have had the MMR. As you are aware MMR is a live virus vaccine and recipients shed those virii for a while after they are innoculated.
Not dead yet.
