A Los Angeles Times report showed that 59 percent of the confirmed cases in the current U.S. outbreak are adults 20 years old and older.
Most of them had no record of being immunized.
Infected adults pose a greater threat to the public than children, because they travel and come into contact with more people.
They also say many adults who were vaccinated against measles as children may need a second vaccination when they’re older — depending on the levels of antibodies in their blood.
Dr. Herminigildo Valle, the chief of staff at Seton Medical Center in Daly City, Calif. told Balitang America that the strength of a measles vaccinations from childhood wears off over time.
“Vaccines have about a 3 percent failure rate. So even if they have the vaccination, they can still get the disease, although not at bad, and not as contagious as someone who wasn’t vaccinated,” Dr. Valle said.
He added: “There’s been reports that within 10 years the level of immunization goes down to a certain point that the antibodies cannot be detected.”
