S-IgG levels and S-antigen contacts contribute to serum neutralization against Wu01 and BA.4/5
infections
INFECTIONS
To explore predictive features for serum neutralization, we first characterized neutralizing activity against Wu01 and BA.4/5 stratified by sex, age, drug immunosuppression, pre-conditions, number of received vaccinations, number of previous infections, and NC-IgG serostatus (Fig.
