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.
