Rotavirus vaccine
When: At 2, 4 and 6 months old
Why your baby needs this: Rotavirus, whose symptoms include fever, diarrhea and vomiting, is the most common cause of acute gastroenteritis in kids, causing the deaths of more than 600,000 children outside the U.S. yearly. Since 2006, when this vaccine was recommended for routine use on American infants, rotavirus prevalence has dropped by 50 percent in our country. This very effective vaccine now prevents 74 percent of all cases, 98 percent of severe cases and 96 percent of hospitalizations due to rotavirus.
