However, most encounters among children aged 511 years occurred during Omicron predominance, when VE significantly declined for adolescents aged 1217 years. Two doses protect against COVID-19associated emergency department and urgent care encounters among children and adolescents. During Omicron predominance, VE of a second dose received 14149 days earlier was 45% and 34% for adolescents aged 1215 and 1617 years, respectively, suggesting that the lower VE observed among children aged 511 years was likely driven by the predominant variant rather than differences in VE across age groups. Second, statistical power for estimating VE against COVID-19associated hospitalizations was limited, resulting in wide CIs for some groups, particularly children aged 511 years.

But in rare cases, patients have . For example, the age SMD calculation comparing unvaccinated versus different vaccinated categories was generated by averaging the pairwise SMD calculations for unvaccinated and 2 doses (14149 days earlier), unvaccinated and 2 doses (150 days earlier), and unvaccinated and 3 doses (7 days earlier).
