Overview
- A mass SMS invitation drew heavy turnout and queues at all 14 public hospitals on Saturday during extended weekend enrollment hours.
- Eligibility now includes all residents 18 and older after an initial focus on seniors and high‑risk groups fell short of sample needs.
- Roughly 20,000 people had enrolled before the weekend push, with organizers aiming for at least 150,000 participants and possibly up to 200,000.
- Volunteers sign informed consent and are randomized 50–50 to receive Pfizer’s Abrysvo or enter a control group, with assignment shown on screen.
- Investigators will track outcomes through health records to gauge reductions in hospitalizations and complications, informing a possible decision as early as 2028.
