The purpose of this study is to evaluate health messaging strategies that help individuals with a high degree of housing-related needs engage in COVID-19 vaccination and testing behaviors. Findings from this research can help other communities determine how best to integrate social needs and COVID-19 prevention services. Participants' contact information will be shared with us by 211 with the participants' previously given consent. The study team will send via text message a link to a survey that includes a screen where they will provide informed consent. Those who provide consent will be randomly assigned to receive one of two surveys. The order of the offers is what varies across the surveys. Participants will be asked, along with other survey items, if they have been vaccinated against COVID-19. If they have not, they will be asked if they are interested in receiving help to receive a vaccine. Participants will also be asked if they are interested in receiving an at-home COVID self-test. If they say yes to assistance with vaccination, a vaccine navigator will call and assist them. If they say yes to receiving a COVID test, the study team will ship them a test that has been procured from the City of St. Louis Mayor's office. One month later participants will be sent a follow-up survey that asks about their experiences either with testing or with vaccination if applicable.

Sequential request strategies will be applied as an intervention. For the Door-In-The-Face Technique, participants first receive a large request they are unlikely to accept, followed by a smaller request that is the true behavior of interest.
Sequential request strategies will be applied as an intervention. For the Foot-In-The-Door Technique, participants are shown an easier first request that they are likely to accept, followed by a larger request that is not the behavior of interest.

Proportion Vaccinated
Via a mobile-optimized web-based survey, the investigators will ask individuals seeking rental/housing assistance if they are thinking about getting vaccinated and report the proportion "already vaccinated."
Time frame: Baseline
Sequential Request Strategy Effectiveness
To compare differences in testing acceptance and vaccination responses by sequential request strategy, the investigators will identify which strategy is associated with greater testing and vaccination intentions.
Time frame: Baseline
Testing and Vaccination Offer Acceptance
At baseline, participants will be offered vaccination support and free a COVID-19 self-test. The investigators will report the proportion of applicants who accept each of the offers.
Time frame: Baseline
Testing and Vaccination Behaviors
After one month follow-up, the investigators will report the proportion of participants who complete the self-test and report the results, and report having been vaccinated since the baseline survey.
Time frame: 1 month follow-up
Rent Relief
The investigators will ask about the outcome of rent or utility assistance.
