Serosurveillance describes using blood samples to determine what percentage of the population has been exposed to a pathogen or has been vaccinated by measuring the presence or absence of antibodies to the pathogen or vaccination. During the COVID-19 pandemic Dr. Bowdish and team built a network of long-term care homes to measure vaccine responses and infection rates, but this infrastructure could have been used to measure virtually any infection or any antibody response. The Hema-Net community came together February 14-16 to present data and share experiences using serosurveillance and published this report. Unfortunately, no funds were made available to continue Dr. Bowdish’s or others serosurveillance networks.
