Prior to say 2008, every year you would see 60 to 65 people come into the United States with measles, but you wouldn’t see it spread,” Offit told The Nation’s Health. “What’s worrisome about what happened in 2008 and what’s happening now is that you see it spread from one American child to another because you have a critical number of unvaccinated children. In other words, then it was sort of like the ball would get thrown up against the wall and it would just bounce back. Now it sticks a little bit because you have a critical number of unvaccinated people.”
Maintaining high immunization rates with the mumps-measles-rubella, or MMR, vaccine is the cornerstone of outbreak prevention, infectious disease experts say. The vaccine is recommended routinely for all children at age 12 months to 15 months, with a second dose at ages 4 to 6.
Prior to the introduction of the first measles vaccine in 1963, nearly all children got measles before their 15th birthday. The virus caused pain and suffering, including as many as 500 deaths each year and 48,000 hospitalizations. According to the National Network for Immunization Information, the vaccine has led to a 99 percent reduction in the incidence of measles in the United States.
Jane Seward, MBBS, MPH, deputy director of CDC’s Division of Viral Diseases, said health care providers and parents need to be aware of the special recommendation for early measles vaccination for infants ages 6 to 11 months when they travel overseas.
