ABSTRACT
In response to the COVID-19 pandemic, COVID-19 vaccines have been developed, and the World Health Oraganization (WHO) has granted emergency use listing to multiple vaccines. Studies of vaccine immunogenicity data from implementing COVID-19 vaccines by national immunization programs in single studies spanning multiple countries and continents are limited but critically needed to answer public health questions on vaccines, such as comparing immune responses to different vaccines and among different populations.

In the United States, clinical trials of COVID-19 vaccines and therapeutics quickly exhausted available clinical research capacity at large medical centers. The NIAID Division of Clinical Research tapped community hospitals to help fill the gap.
