CoVAcS Trial Summary

This trial is testing a method to increase vaccine hesitancy and lack of access to the COVID-19 vaccine among Veterans.

Who is the study for?
This trial is for unvaccinated U.S. Veterans in VISNs 16 and 21, including those hesitant or with limited vaccine access. Eligible participants have visited a primary care clinic after the trial started and are not in another COVID-19 study, at high suicide risk, severely demented, allergic to vaccines, in hospice care or unable to be contacted by phone.Check my eligibility
What is being tested?
The study aims to increase COVID-19 vaccination rates among Veterans through a Vaccine Acceptance Intervention using Motivational Interviewing plus Implementation Facilitation. It targets those who haven't started or completed their vaccination due to hesitancy or access issues.See study design
What are the potential side effects?
Since this intervention involves motivational interviewing rather than medication or vaccines directly administered as part of the trial, there are no direct medical side effects associated with it.

CoVAcS Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Intervention ArmExperimental Treatment1 Intervention
The VAMC Internal Facilitator will partner with the trial External Facilitators (research team and designated External Facilitators in VISNS 16 and 21) to adapt and implement the study intervention to best meet the needs and preferences of their VAMC site. In addition, each CBOC and clinic affiliated with a VAMC in the Intervention arm will need to identify a Site Champion to provide clinic-specific information to facilitate implementation of the Vaccine Acceptance Intervention at their clinic or CBOC. In addition, for clinics and CBOCs assigned to the Vaccine Acceptance Intervention, VAMC, clinic and CBOC leadership will need to agree to release PACT staff for an initial two-hour Motivational Interviewing (MI) training, and at least one 60-minute post-training consultation session over the one-year trial period. There will be additional consultation sessions offered to intervention clinics and CBOC staff, but these will be optional.
Group II: Usual Care ArmActive Control1 Intervention
A VAMC assigned to Usual Care will have no specific trial intervention requirements beyond their usual level of participation in national and local initiatives to improve COVID-19 vaccine acceptance. At both Intervention and Usual Care sites, the study team will perform quarterly "environmental scans". The environmental scan survey will include questions about site specific barriers to COVID-19 vaccination (first dose and second dose if needed), current programs/initiatives in the clinic or local community that are improving or have had no impact on vaccination rates, and the perceived importance that the VAMC/CBOC clinic staff is placing on vaccination (Environmental Scan Survey, in preparation). At Usual Care sites, a point of contact will be chosen from each clinic and CBOC to complete the environmental scan, and at Intervention sites, the Site Champion (see below) will perform the quarterly scan.
