Studies that compared orthologs of the angiotensin-converting enzyme 2 receptor also revealed that various species might be susceptible to SARS-CoV-2. However, similarities in the ACE-2 receptor alone are not good indicators of susceptibility. The 2020 sampling periods were during the dominance of the ancestral Wuhan-Hu-1 strain, whereas the July 2021 sampling was conducted during the dominance of the Delta variant, which was more contagious than other SARS-CoV-2 variants at the time.
Therefore, targeted surveillance was conducted in December 2021 among animals that may have encountered the infected hippos and were thought to be susceptible or of interest due to their conservation status. These included large felines and primates.

SARS-CoV-2 Antibody Dynamics in Healthcare Workers after mRNA VaccinationSince the emergence of SARS-CoV-2, maintaining healthcare worker (HCW) health and safety has been fundamental to responding to the global pandemic. Vaccination with mRNA-base vaccines targeting SARS-CoV-2 spike protein has emerged as a key strategy in reducing HCW susceptibility to SARS-CoV-2, however, neutralizing antibody responses subside with time and may be influenced by many variables. We sought to understand the dynamics between vaccine products, prior clinical illness from SARS-CoV-2, and incidence of vaccine-associated adverse reactions on antibody decay over time in HCWs at a university medical center. A cohort of 296 HCWs received standard two-dose vaccination with either bnt162b2 (Pfizer/BioNTech) or mRNA-1273 (Moderna) and were evaluated after two, six, and nine months. Subjects were grouped by antibody decay curve into steep antibody decliners gentle decliners. Vaccination with mRNA-1273 led to more sustained antibody responses compared to bnt162b2. Subjects experiencing vaccine-associated symptoms were more likely to experience a more prolonged neutralizing antibody response. Subjects with clinical SARS-CoV-2 infection prior to vaccination were more likely to experience vaccination-associated symptoms after first vaccination and were more likely to have a more blunted antibody decay. Understanding factors associated with vaccine efficacy may assist clinicians in determining appropriate vaccine strategies in HCWs.
