Rotavirus Vaccine May Protect Against Type 1 Diabetes

The vaccine that prevents rotavirus, which can cause severe gastric problems in children, may have another benefit: lowering the risk for Type 1 diabetes in toddlers.

Rotavirus can leave children badly dehydrated and is sometimes fatal. Fortunately, there are two vaccines for the disease, easily administered by putting drops in the child’s mouth at ages 2 months, 4 months and (for one version of the vaccine) 6 months. Both vaccines are more than 90 percent effective.
