About this study

Investigators will use a randomized controlled trial to test the effectiveness of HALT COVID educational outreach by HALT COVID Ambassadors. HALT COVID Ambassadors will receive training to answer common vaccine questions & address misconceptions; conduct motivational interviewing; and implement basic behavioral economics and related strategies to remove barriers to vaccination. A random sample of FQHC patients will be identified in EHR data downloads of adult patients seen in the last year and contacted by telephone to gain consent and assess eligibility. A total of 100 individuals will be enrolled into the trial and randomized to intervention (engagement with the HALT COVID Ambassador over a 1 month period via in-person or virtual sessions exploring their own questions and concerns about vaccines) or usual care (no extra engagement). Baseline, 1-month, and 2-month follow-up surveys will assess for vaccine likelihood.

Inclusion criteria

  • Unlikely to vaccinate in next month
  • Age >=18 years

Treatment and study plan

Community Health Worker engagement

Behavioral

3-4 in-person or virtual engagements (individual or group sessions) over 1 month, each engagement lasting 30 minutes to 1 hour

Primary outcomes

  1. Difference in Proportion of Participants "Likely to Vaccinate" Between Study Arms at Month 1

    Time frame: Month 1 follow-up

    Vaccine likelihood will be measured using a single question adapted from the CEAL Common Survey (i.e., "On a scale from 1 to 7, with 1 being 'not at all likely' and 7 being 'very likely', how likely are you to get a COVID-19 vaccine in the next month?"), with "likely to vaccinate" defined as a score of 5-7.

Secondary outcomes

  1. Difference in Proportion of Participants "Likely to Vaccinate" Between Study Arms at Month 2

    Time frame: Month 2 follow-up

    Vaccine likelihood will be measured using a single question adapted from the CEAL Common Survey (i.e., "On a scale from 1 to 7, with 1 being 'not at all likely' and 7 being 'very likely', how likely are you to get a COVID-19 vaccine in the next month?"), with "likely to vaccinate" defined as a score of 5-7.

  2. Difference in Proportion of Participants Who Have Received >=1 Dose of Vaccine Between Study Arms at Month 1

    Time frame: Month 1 follow-up

    Receipt of vaccination will be measured by self-report

  3. Difference in Proportion of Participants Who Have Received >=1 Dose of Vaccine Between Study Arms at Month 2

    Time frame: Month 2 follow-up

    Receipt of vaccination will be measured by self-report
