Stability testing of reconstituted measles and rubella combination vaccines.

<p>After incubation of reconstituted vaccines at 4°C (A), 25°C (B), or 35°C (C), titres of measles and rubella viruses in the vaccines were measured by plaque assays. Filled squares and open circles indicate titres of measles and rubella viruses, respectively. Means of three vials are shown. Error bars indicate standard deviations.</p

Rubella IgG seroprevalence measured by ELISA in different age groups from representative populations in Lao PDR, 2014.

<p>*An ELISA value of 10 IU/ml was considered positive. †Individuals 5 to 14 years old and 15 to 21 years old were among the targeted age groups of supplementary immunization activities conducted in 2011 using the MR combination vaccine with coverage of 97%. Their IgG prevalence was estimated to be 88.2% (95%CI: 84.5–91.8).</p

Best-fitting values of the force of infection in Lao PDR before the 2011 SIA among participants aged < 15 and ≥ 15 years, obtained by the selected best-fitting model (model B) for different assumptions about the reduction in the force of infection after the SIA, and CRS incidence per 100,000 live births among women aged 15–44 years after weighting by the number of live births occurring among women in different maternal age groups.

Measles IgG seroprevalence measured by ELISA in different age groups from representative populations of Lao PDR, 2014.

<p>*An ELISA value of 120 mIU/mL was considered positive. †Individuals 5–14 years old and 15–21 years old were among the targeted age groups of supplementary immunization activities conducted in 2011 using the MR combination vaccine with coverage of 97%. Their IgG prevalence was estimated to be 86.8% (95% CI: 83.0–90.6).</p
