Measles outbreaks have occurred in some countries despite supplementary immunization activities (SIA) using measles-containing vaccine with high vaccination coverage. We conducted a cross-sectional seroprevalence survey to estimate population immunity in Lao Peoples Democratic Republic where repeated mass immunization has failed to eliminate measles.
In this nationwide multistage cluster sampling survey conducted in 2014 based on probability proportionate to size sampling blood samples were collected from 2135 children and adults living in 52 randomly selected villages. Anti-measles and anti-rubella IgG were measured and IgG prevalence was calculated. We applied mathematical modelling to estimate the number of cases of congenital rubella syndrome (CRS) in 2013 that were averted by the 2011 SIA. A stability testing was applied to the MR vaccine at 4°C 25°C and 35°C to examine stability differences between measles and rubella vaccine components. Measles IgG prevalence was significantly lower in the target age groups (5-21 years) of the 2011 SIA using a combination vaccine for measles and rubella vaccine (MR vaccine) than in young adults (22-39 years) (86.8% [95% CI: 83.0-90.6] vs. 99.0% [98.3-99.8]; p<0.001) whereas rubella IgG prevalence was significantly higher (88.2% [84.5-91.8] vs. 74.6% [70.7-78.5]; p<0.001). In the SIA target age groups prevalence of measles IgG but not rubella IgG increased with age. CRS cases prevented in 2013 ranged from 16 [0-50] to 92 [32-180] if the force of infection had remained unchanged or had been reduced by 75% respectively. In freeze-dried conditions the measles vaccine component was more heat sensitive than the rubella component.
Inconsistent IgG prevalence between measles and rubella in Lao PDR can be partly explained by different stability of the measles and rubella vaccine components under heat exposure. Suboptimal vaccine handling may cause insufficient immunogenicity for measles which subsequently leads to an outbreak despite high SIA coverage while direct evidence is lacking. Temperature monitoring of the vaccine should be conducted.
