Seroprevalence of antibodies against SARS-CoV-2 in the Valencian Community (Spain) as of October 2022.

ABSTRACT:

Objective

To estimate the seroprevalence of SARS-CoV-2 antibodies in the Valencian Community (Spain) in October 2022, when BA.5 was the predominant variant.

Method

Cross-sectional, region-wide, population-based serosurvey study in 88 randomly selected primary care centers of the Valencian Community.

Results

Seroprevalence of anti-nucleocapsid (indicative of past infection) and total receptor binding domain (indicative of past infection or vaccination) antibodies was 71.0% (confidence interval [CI]: 67.8-74.2) and 98.4% (CI: 97.5-99.3), respectively. 66.7% (CI: 63.4-70.0) of the population shows hybrid immunity, but only 43.2% in those 80 and over.

Conclusions

The high proportion of hybrid immunity detected is relevant for public health strategies. A second vacc
