Active duty service members needed for COVID-19 vaccine effectiveness study

By Lori Newman

A team of researchers is conducting an observational study involving active duty service members who have received COVID-19 vaccines. The Vaccine Effectiveness and Immune Response of SARS-CoV-2 Vaccines in Active Military Personnel study aims to help the Defense Department better understand how well COVID-19 vaccines protect service members.

“The VIRAMP study will assess vaccine protection against both symptomatic and asymptomatic SARS-CoV-2 infection, including emerging variants,” said Air Force Col. (Dr.) Jason F. Okulicz, Infectious Disease physician and principal investigator, Brooke Army Medical Center.

Study participants must:

  • Be active duty service members 18-65 years of age stationed at Joint Base San Antonio.
  • Have received or are planning to receive a COVID-19 vaccine.
  • Be willing to provide blood and saliva samples as required throughout the study.
  • Be healthy at the time of enrollment.
  • Not anticipate military separation or deployment within six months of enrollment.
