Cumulative incidence curves showing the probability of rotavirus vaccination for children who received pentavalent vaccine before and after the upper age limit of rotavirus vaccine administration, El Salvador, 2011.

The probability of rotavirus vaccination is shown with solid lines and confidence intervals are shown as dotted lines. The top row shows the probability of vaccination with the first dose of rotavirus vaccine, among children who received the first dose of pentavalent vaccine before the first dose rotavirus vaccine upper age limit (15 weeks of age) in the left column and after the upper age limit in the right column. The bottom row shows the probability of vaccination with the second dose of rotavirus vaccine, among children who received the second dose of pentavalent vaccine before the series rotavirus vaccine upper age limit (8 months of age) in the left column and after the upper age limit in the right column. The gray boxes highlight the minimum acceptable age until 30 days after the recommended age for the rotavirus dose.
