Measles Antibody Titers in Early Infancy

Antimeasles antibodies in preterm infants during early infancy in Turkey

“…3, Table 2). [21][22][23] Mean antibody values after measles infection are two-to-four times higher than those after vaccination. 24 The immunity acquired by vaccination lasts at least 20-25 years.…”

“…16 Kamat et al demonstrated that 26% of preterm infants were seronegative at 3 months. 18 Rau et al reported from India that 97% of preterm infants are susceptible to measles by 5 months. 19 Glick et al demonstrated that 6% of preterm infants were seronegative at 3 months.…”

A study of maternally derived measles antibody in infants born to naturally infected and vaccinated women

“…[9][10][11][12] and infants born to vaccinated mothers acquire a lower level of measles antibody, which disappears at an earlier age, than infants born to mothers who have had natural measles infection . Therefore, children born to vaccinated mothers may be vulnerable to natural measles infection and be able to respond to measles vaccine at a younger age than infants of unvaccinated mothers [9,10,[12][13][14][15][16][17]. In the future, as the proportion of mothers who have been vaccinated increases, it may be possible to reduce the recommended age of measles vaccine, for all or for selected groups of children [9,10,[12][13][14].…”

Protecting infants against measles in England and Wales: a review

“…In an American survey25 of predominantly premature infants admitted to a neonatal intensive care unit, almost three-quarters of infants aged 4–5 months were seronegative to measles. Linder et al 26 surveyed 195 Israeli newborns to examine the degree of transplacental transfer of measles antibodies from vaccinated and naturally immune mothers to preterm and full term infants.…”
