DOVER, Del. – With measles cases on the rise across the United States, the Delaware Division of Public Health is urging people to ensure they are vaccinated against the highly contagious virus.
The Centers for Disease Control and Prevention recommends the measles, mumps, and rubella vaccine, known as the MMR vaccine, as the best protection. The vaccine is 93 percent effective after one dose and 97 percent effective after two doses. Children between 12 months and 12 years old can also receive the MMRV vaccine, which includes protection against varicella (chickenpox).
According to health officials, children should receive two doses of the MMR or MMRV vaccine—one between 12 and 15 months old and a second between 4 and 6 years old. Older children, teenagers, and adults who are unvaccinated may need one or two doses, separated by at least 28 days. Those unsure of their vaccination status should check with their health care provider or visit a public health clinic.
Travel Considerations
Measles spreads easily through coughing and sneezing, making vaccination especially important for travelers. The CDC has traditionally recommended that international travelers be fully vaccinated before departure. However, with the recent increase in cases, health officials advise that domestic travelers also consider vaccination.
Infants 6 to 11 months old should receive one dose of the MMR vaccine before travel, followed by two more doses after their first birthday. Adults who are unsure of their vaccination status may also need one or two doses before traveling.
Delaware's Measles Status
As of March 20, Delaware has reported no measles cases in the past decade. However, the Division of Public Health continues to monitor outbreaks across the country.
Measles can cause severe complications, including pneumonia, encephalitis (brain inflammation), and death, particularly in unvaccinated individuals.
MMR and MMRV vaccines are covered under most health insurance plans. People without coverage can visit a public health clinic to inquire about free vaccines for children and qualifying adults.
