Oa. Babaniyi et al., LOSS OF MATERNALLY-ACQUIRED MEASLES ANTIBODY DURING INFANCY IN ILORIN, NIGERIA, Journal of tropical pediatrics, 41(2), 1995, pp. 115-117
In a study of the prevalence of measles antibody in infants aged 1-9 m
onths detectable antibody was present in 32 per cent. Prevalence was h
ighest in the 4-7-week age group and dropped rapidly with increasing a
ge. In infants 28-35 weeks old, only 7 per cent had detectable antibod
y. Logistic regression analysis showed that by the end of the seventh
month of life only 10 per cent would carry antibody against measles.
