Measles vaccine: A real immunity super-booster

The Pediatric Insider

What if there was an intervention that could reduce a child’s risk of death from infection—from any infection—by half? And that one intervention’s immune-boosting power lasted 2 or 3 years. It’s also very safe, with a very small risk of any serious side effects.

Pat yourself on the back. Your child has probably already had it, and your entire community is getting benefit from fewer circulating infections.

A recent study published in Science looked at long-term changes in immunity following measles vaccination in populations worldwide. It’s known that measles infection put people at risk for other infections for several weeks or months afterwards – natural infection seemed to suppress the immune system. Using data correlating vaccinations, measles cases, and infectious disease deaths, the authors found that the immune suppression had a much more serious and lasting impact than had been thought. For two to three years after natural measles, the all-cause infectious mortality spiked upwards. Measles vaccination, in other words, doesn’t just prevent measles deaths—it prevents deaths from any infection. For years.

The effect is striking in its intensity. Overall, when measles was common years ago, it accounted for about half of all deaths from infection (combining the direct effect of measles infection itself with the immune suppressive effect.) In some of the most resource-poor countries, it probably accounted for up to 90% of all infectious deaths. Think about that. One vaccine, preventing all of those deaths. The authors only looked at mortality—if you consider other morbidity, hospitalizations, costs, and misery, the positive effect of measles vaccinations would be much, much higher.

Boosting immunity doesn’t just help the individual child. The entire community is protected when the risks of infection drop, including the risk to newborns and elderly people, or people who are already sick.

Don’t be fooled by the fake immune-boosters—the colon cleanses, the “Airborne”, the pills and potions pushed by the multi-billion dollar supplement industry. Real immune boosting does not rely on magic. Get enough quality sleep, eat a healthy diet, get some exercise, and take reasonable precautions like washing your hands and avoiding sick people. And, please, make sure you and your children have received all of the recommended vaccines. Protect yourself, protect your kids, protect your communities. Vaccinate!

  1. Thanks, Dr. Roy! Having intelligent and caring pediatricians has been the biggest factor assuring me that vaccinating my children is the right decision. I just couldn’t see the doctors who have cared for my children so well as uninformed or uninterested in what’s best for them.
