View original scientific description
In collaboration with community-based organizations, this study will focus on increasing RSV vaccine use among Latinos. The study will determine how effective community health worker counseling and text-message approaches are to (1) increase RSV vaccine use among older adults (Motivate phase) and (2) encourage younger adults to discuss RSV vaccination with their older friends and family members (Activate phase).
Interventions
BEHAVIORAL
Motivate Aim: CHW text message reminders and counseling
Participants receive both text message reminders and a counseling session, along with information about RSV and the vaccine, to encourage RSV vaccine uptake.
BEHAVIORAL
Motivate Aim: CHW text message reminders only
Participants receive text message reminders along with information about RSV and the RSV vaccine to encourage vaccine uptake, but do not receive the counseling intervention
BEHAVIORAL
Activate Aim: CHW text message reminders and counseling
Participants receive both text message reminders and a counseling session, along with information about RSV and the vaccine, to encourage discussion of RSV vaccine uptake among older adults in their social networks
BEHAVIORAL
Activate Aim: CHW text message reminders only
Participants receive text message reminders along with information about RSV and the vaccine to encourage discussion of RSV vaccine uptake among older adults in their social networks, but do not receive the counseling intervention

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
