Measles Virus May Wipe Out Immune Protection for Other Diseases
Some families choosing not to vaccinate argue that measles is just a pesky childhood illness to be endured. But two new studies illustrate how skipping the measles vaccine carries a double risk. Not only does it leave a child vulnerable to a highly contagious disease, but also, for individuals who survive an initial measles attack, the virus increases their vulnerability to all kinds of other infections for months — possibly even years — after they recover.
The research begins to explain something surprising that happened when the measles vaccine was introduced in the U.S. in the 1960s. Rates of childhood deaths from other diseases fell precipitously. The same thing happened as the vaccine was introduced around the world. (NPR)
