“…It is recognized that measles antibody levels induced by vaccination are lower than antibody levels induced by the disease (23,24). Several studies have shown that newborns from vaccinated mothers have both lower levels of transplacentally transferred measles antibodies than infants born from women who had measles and an earlier decline in maternal antibodies (1,4,12,15,30,37,38,40).…”

The optimal age for measles vaccination is an important health issue, since maternal antibodies may neutralize the vaccine antigen before a specific immune response develops, while delaying vaccination may increase the risk of complicated diseases in infants. However, measles vaccination impacts the duration of protection afforded by transplacental transfer of maternal antibodies: vaccination-induced maternal antibodies disappear faster than disease-induced antibodies. In order to maintain protection against measles in infants, it is important to monitor the dynamics of this phenomenon in vaccinated populations. To assess the current situation in France, a multicenter, prospective seroepidemiological study was conducted in seven French hospitals between October 2005 and January 2007. Maternal measles antibody concentrations from 348 infants 0 to 15 months old were measured using the plaque reduction neutralization assay. Geometric mean concentrations and the percentage of infants with maternal measles antibody concentrations above the protection threshold (>120 mIU/ml) were assessed according to age. Results show that after more than 20 years of routine measles vaccination in France, maternal measles-neutralizing antibodies decrease dramatically in French infants by 6 months of age, from 1,740 mIU/ml for infants 0 to 1 month old to 223 mIU/ml for infants 5 to 6 months old, and that 90% of infants are not protected against measles after 6 months of age. Infant protection against measles could be optimized both by increasing herd immunity through an increased vaccine coverage and by lowering the age of routine vaccination from 12 to 9 months.

“…Some researchers have suggested that the time of administering the first vaccine dose should be advanced. 15,16 However, other studies have reported that vaccination in younger infants (6-9 mo) usually results in lower seroconversion rates and neutralizing titers compared with immunization in older infants (12-15 mo). 17 In China, the first dose of measles vaccine is offered at 9 mo of age.…”

“…Some researchers have suggested that the timing of the first vaccine dose should be advanced. 39,40 Aaby et al also found that child mortality may be reduced if measles vaccine is given earlier than currently recommended by international organizations. 41 With the presence of maternal antibody, child mortality in low-income countries may be reduced via a 2-dose vaccination schedule with the first dose at 4-6 months (earlier than currently recommended) and a booster dose at 9-12 months of age.…”

This study examined the epidemiological and serological characteristics of measles in Dongguan, China. From 2005 to 2014, a total of 8,224 measles cases were reported in Dongguan, 33.5% of which were aged <1 y and 30.6% >14 y. From 2005 to 2014, the proportion of the <1 y measles cases increased year by year from 24.3% to 47.9%. Of the cases aged 8 months (n D 6,768 cases), only 11.6% had been immunized with at least one dose of measles vaccine. Of the 2,213 cases who had never been immunized with measles vaccine, immigrants accounted for 82.4%. 52.4% of the measles cases were diagnosed with pneumonia, and 12 cases died from respiratory failure. Seroprevalence rate in women and their newborns was 86.0% and 82.5%, respectively. Measurement of serum measles antibody levels for infants aged less than 8 months indicated that seroprevalence rate dramatically declined from 97.3% at birth to 9.3% and 13.2% at 6-and 7-month old. The existence of a sufficient pool of unvaccinated people (especially immigrants) and decreased level of passively transferred measles antibodies in infants from vaccinated mothers contributed to the sustained transmission observed in Dongguan. In addition to high routine vaccination coverage, new strategies and innovations for measles vaccination are needed to eliminate measles.
