No, I've had Measles and German Measles. ( all my siblings did too). When my neice had german measles I was fine with her I had full immunity to both. As for it being a Killer there are thousands who are fine.
With these injections they have been giving girls at 5 and at about 14 what they don't tell you is you are not fully immune for the rest of your life, they give the final injection at 14/15 to see female through the child bearing years.
Only problem now is the age range is a lot later.
It's a great thing nature, a womans body gathers all these immunities, and when she's having a baby their immune too, and they are passed on after the baby is born to give it a good start until they are strong enough themselves. So by doing this every child has a better chance surviving it's in the genes.
