Outbreak of measles among persons with prior evidence of immunity 2014, Rosen, Clin Infect Dis

Until now it was believed that although measles vaccinated against measles can become infected, they can not infect others (the authors clearly did not read the previous article, and dozens of other articles on measles outbreaks in fully vaccinated schools.) And, it turned out, Twice a girl who was vaccinated with a twenty-two-year-old girl infected four people with measles, three of them were medical workers, all four were either vaccinated in two doses or they had measles antibodies.
Here are some articles about measles outbreaks in full or almost fully vaccinated collectives:

Vitamin A levels and severity of measles, New York City. 1992, Frieden, Am J Dis Child

Measured the level of vitamin A in 89 children under 2 years old with measles in New York, and compared with the control group, almost all were Latina and African Americans, 22% had a low level of vitamin (less than 0.7). % was a borderline level (0.7-0.87), children with a vitamin deficiency often had a high fever (above 40), the temperature stayed longer, and they were 2 times more likely to be hospitalized, and children with borderline vitamin levels were also hospitalized more often. control group, the level of vitamin A was not lowered, and the average level of vitamin A in them was 2 times higher than in the group of measles patients (0.92 vs. 1.9 umol/l).
Six children had a documentary confirmation of the vaccination.The symptoms of the disease, the level of the vitamin and the number of antibodies they had were exactly the same as those of not who have documented evidence of vaccination.
Lack of vitamin A weakens cellular immunity and reduces the production of antibodies.
The authors conclude that half of the children with measles in New York have a low or borderline vitamin A level, and this leads to a more severe illness. They offer to give vitamin A also to children in the United States, not just in the countries of the third world.
