March 1: An NIH-funded research team launches a study to assess performance and usability of a smartphone app paired with the Quidel QuickVue At-Home COVID-19 Test, which just received an Emergency Use Authorization (link is external) (EUA) from the FDA for use with a prescription.

March 1: NIH halts two  Accelerating COVID-19 Therapeutic Interventions and Vaccines (ACTIV)-3 clinical trial substudies for hospitalized patients: one examining the investigational monoclonal antibody therapy VIR-7831, and another evaluating the investigational combination monoclonal antibody therapy containing BRII-196 and BRII-198. There were no safety concerns, but the Data and Safety Monitoring Board (DSMB) determined that there was a low likelihood of clinical value in hospitalized patients.

March 2: NIAID Director Anthony Fauci donates his much-used model of SARS-CoV-2 to the Smithsonian’s National Museum of American History. Fauci is awarded the museum’s signature honor—the Great Americans Medal—for his leadership during the COVID-19 pandemic and lifetime devotion to the treatment and eradication of infectious diseases.

March 2: NICHD announces that it will lead a research effort called “Collaboration to Assess Risk and Identify Long-term Outcomes for Children with COVID (CARING for Children with COVID)”to understand how SARS-CoV-2, the virus that causes COVID-19, affects children, who account for roughly 13% (link is external) of the total cases of COVID-19 in the United States.

March 2: NIH halts a clinical trial evaluating the safety and effectiveness of COVID-19 convalescent plasma in treating emergency department patients who developed mild to moderate symptoms of COVID-19, the disease caused by the coronavirus SARS-CoV-2. NIH determined that the treatment was unlikely to benefit this group of patients.

March 3: NIH Director Francis Collins, in his all-staff email, announces that employees scheduled for qualified urgent medical treatments will be prioritized to receive a COVID-19 vaccine.

March 5: NIH Director Francis Collins updates staff on the improving COVID-19 vaccine supply; NIH received 2,400 Pfizer vaccine second doses from the federal supply chain for Maryland-based employees. Additionally, the Montana Department of Public Health and Human Services supplied 100 Moderna vaccine second doses for staff at NIAID’s Rocky Mountain Labs (Hamilton, Montana). NIEHS in North Carolina also received 230 first doses of the Moderna vaccine. Collins also announces that over the weekend, FDA issued an EUA for the Johnson & Johnson single-dose COVID-19 vaccine.

March 8: NIH launches the last of three clinical trials to evaluate the safety and efficacy of the anticoagulant apixaban 2.5 mg (Eliquis) to prevent life-threatening blood clots. The phase 3 trial is recruiting convalescing adults diagnosed with COVID-19 who are within 45 days of being hospitalized. NHLBI oversees the worldwide trials that are part of the initiative.

March 10: In an all-staff email, NIH Deputy Director for Management Alfred Johnson announces that HHS has extended authorization for supervisors to approve excused absences for employees caring for dependents at home through September 10, 2021.

March 11: The one-year anniversary of the day that the World Health Organization declared the COVID-19 pandemic.

March 12: In his email message to staff, NIH Director Francis Collins acknowledges that the past year has been a long and difficult one. “But there is encouraging news to report: nationally, COVID-19 case numbers are gradually dropping, and with three highly effective COVID-19 vaccines in distribution, more people are being vaccinated every day.” He also reminds staff of the support resources available including about-to-be-launched virtual well-being coaching sessions and a Parents and Caregivers of Children virtual support group.

March 19: NIH Director Francis Collins announces in his all-staff email that all phase 3–eligible employees have been invited by Occupational Medical Services to schedule their COVID-19 vaccination appointments. He notes that vaccine confidence is improving, pointing to an ongoing research project by the Kaiser Family Foundation Vaccine Monitoring Dashboard that tracks the public’s attitudes and experiences with COVID-19 vaccination.

March 22: Results from a large clinical trial, funded in part by NIAID, indicate that AstraZeneca’s COVID-19 vaccine, AZD1222, is well-tolerated and protects against symptomatic COVID-19 disease including severe disease or hospitalization.

March 25: A study led by NIDCR finds evidence that SARS-CoV-2, the virus that causes COVID-19, infects cells in the mouth. The findings suggest that oral cells and saliva play a bigger role in SARS-CoV-2 infection than previously thought, and may contribute to transmission within and outside the body. (Nat Med 2021; DOI:10.1038/s41591-021-01296-8)

March 26: In his all-staff email, NIH Director Francis Collins announces that 2,340 vaccine doses were received to cover all phase 3 employees in Maryland, as well as to phase 4 employees who are 75 and older.
