Measles is a disease of malnutrition—and especially inadequate levels of vitamin A—that vaccination can’t prevent, a new study has discovered.
Children who are malnourished don’t have the antibodies to protect them from measles—even though they have been vaccinated.
Researchers from McGill University analysed measles antibodies in 600 children in South Africa who had all been given the MMR jab. By the time they were five years old, their antibody levels were at least 24 percent lower than in children who were well nourished, some of whom hadn’t been vaccinated.
A healthy diet influences the protection the MMR provides, the researchers said.
