Post COVID-19 Vaccination Analysis in Healthcare Worker Recipients

As some of the first recipients of SARS-CoV-2 vaccines under emergency authorization use, healthcare workers represent a diverse subpopulation, that are now moving through the immune response to the Pfizer and Moderna mRNA vaccines. As individual responses may vary, this provides an opportunity to evaluate levels of IgG response in relation to age, gender, comorbidities and other factors that may influence immunity. We recognize that, though this is only part of the immune response that may be protective for severe COVID-19 disease, it is a first step in understanding the level and durability of post vaccination SARS-CoV-2 antibodies. This small, pilot study will evaluate the immune response over time by measuring serum semi-quantitative SARS-CoV-2 IgG from healthcare vaccinees at various timepoints. A high-level review of reactions related to the vaccinations will be performed with the same population of healthcare workers.
