Did you read the part where that 0.1% mortality rate is for children in developed countries - countries where the parents have access to thousands of dollars in healthcare treatment when their kids actually get sick? Did you look up what it is in developing countries? It can be as high as 10% in some places.
You do realize almost
half a million kids still die from measles every year because they aren't vaccinated, right?
How about "Infant mortality is sharply decreasing thanks to immunizations, especially against the measles, which
contributed to a decrease by 25% in the children under 5 mortality rate worldwide."
By the way this is for measles, which is far less deadly than pertussis (an infant mortality rate of 1.2% in
developed countries).
