Pigs are not susceptible to SARS‐CoV‐2 infection but are a model for viral immunogenicity studies

Abstract

Conventional piglets were inoculated with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) through different routes, including intranasal, intratracheal, intramuscular and intravenous ones. Although piglets were not susceptible to SARS‐CoV‐2 and lacked lesions or viral RNA in tissues/swabs, seroconversion was observed in pigs inoculated parenterally (intramuscularly or intravenously).
