"In 83 individuals immunized with measles vaccine, the vaccine strain genome was
detected in 10 (71.4%) of 14 recipients whose PBMC were obtained within 2 months of
vaccination."

damage human thymus. J Infect Dis. 2001 Feb 1; 183(3): 498-502. Johns Hopkins
University, Baltimore, Maryland, USA. PMID: 11133383
[Question: How would the thymic-damage findings be exacerbated if tested tissues
were selected to represent humans with excessively increased susceptibility, eg, an
infant with persisting colic and/or persisting otitis?]
MV & Vitamin A

healthy children. Acta Paediatr Jpn. 1998 Aug; 40(4): 345-9. PMID: 9745778
"Serum retinol levels have been shown to be depressed during measles infection. This
study aims to demonstrate whether there is any decrease in serum vitamin A level
following immunization with live viral vaccine and its relation with vaccine
seroconversion in children with measles. Since many children receive measles vaccine
alone or in combination with measles-mumps-rubella vaccine, we studied serum vitamin
A levels and antibody levels in healthy, well-nourished children before and after
immunization with monovalent and combined live attenuated measles vaccine…
CONCLUSION: Serum vitamin A levels are reduced following vaccination with
monovalent and combined live attenuated measles vaccines."
85. Vitamin A administered with measles vaccine to nine-month-old infants does not
reduce vaccine immunogenicity. J Nutr. 1999 Aug; 129(8): 1569-73. PMID 10419992

"Among malnourished infants, the geometric mean titer was significantly greater in the
vitamin A group compared to the placebo group (ratio of geometric means, 1.57; 95%
confidence interval, 1. 18-2.0), but seroconversion rates did not differ."
[Comment: note the theoretical implication that malourished children may have lower
cell-mediated immunity and thus generate increased antibody immunity. This is
consistent with immunity lab-data in many autistic children.]

measles immunization. Pediatr Infect Dis J. 1999 Aug; 18(8): 747-8. PMID 10462357
