Neutralization of SARS-CoV-2 Omicron and other variants in serum from children with vaccination-induced myocarditis.

Our study demonstrates that children who developed SARS-CoV-2 vaccination-induced myocarditis and may not receive another vaccination, could be susceptible to infection with Omicron and emerging variants. We observed higher neutralizing antibody titers in myocarditis patients vs. healthy vaccinated children, but significantly lower neutralization titers against Omicron in both groups. © Published by Oxford University Press on behalf of the Infectious Diseases Society of America 2022.
