We assessed serum neutralization of Omicron BA.5 in children following SARS-CoV-2 infection during the Delta or Omicron BA.1/BA.2 variant period. Convalescent BA.5 titers were higher following infections during the Omicron BA.1/BA.2 vs Delta variant period, and in vaccinated vs unvaccinated children. Titers against BA.5 did not differ by age group.
我们评估了在 Delta 或 Omicron BA.1/BA.2 变异株流行期间感染 SARS-CoV-2 的儿童血清对 Omicron BA.5 的中和作用。与 Delta 变异株流行期间相比，Omicron BA.1/BA.2 流行期间感染后 BA.5 的恢复期滴度更高，且在接种疫苗和未接种疫苗的儿童中也是如此。针对 BA.5 的滴度与年龄组无关。
