NIH Begins Study of COVID-19 Vaccination During Pregnancy and Postpartum
June 23, 2021
A new observational study has begun to evaluate the immune responses generated by COVID-19 vaccines administered to pregnant or postpartum people. Researchers will measure the development and durability of antibodies against SARS-CoV-2, the virus that causes COVID-19, in people vaccinated during pregnancy or the first two postpartum months. Researchers also will assess vaccine safety and evaluate the transfer of vaccine-induced antibodies to infants across the placenta and through breast milk.

NIH Clinical Trial Evaluating Moderna COVID-19 Variant Vaccine Begins
March 31, 2021
An investigational vaccine designed to protect against the B.1.351 SARS-CoV-2 variant has been administered as part of a new Phase 1 clinical trial evaluating the vaccine candidate’s safety and immunogenicity in adult volunteers. The vaccine, known as mRNA-1273.351, was developed by the biotechnology company ModernaTX, Inc., based in Cambridge, Massachusetts. The trial is led and funded by NIAID. The trial will enroll approximately 210 healthy adult volunteers at four clinical research sites in the United States that are part of the NIAID-funded Infectious Diseases Clinical Research Consortium (IDCRC).
Clinical Trial Evaluating Mixed COVID-19 Vaccine Schedules Begins
June 1, 2021
The National Institutes of Health has started a Phase 1/2 clinical trial in which adult volunteers who have been fully vaccinated against COVID-19 will receive booster doses of different COVID-19 vaccines to determine the safety and immunogenicity of mixed boosted regimens. The National Institute of Allergy and Infectious Diseases (NIAID), part of NIH, is leading and funding the study through the Infectious Diseases Clinical Research Consortium, a clinical trials network that encompasses the Institute’s long-standing Vaccine and Treatment Evaluation Units (VTEUs).
