Participant Information
A clinical research study to evaluate an investigational vaccine for the prevention of COVID-19 in adults is now enrolling.
The Study has 3 Parts
Screening Period
(up to 14 days) You will visit the study center to see if the study is right for you, learn more about it, and decide whether you want to take part. |
Study treatment
(4 weeks) You will visit the study center 2 or 3 times for study assessments. At 2 of these visits, you will receive the study injection (either the investigational vaccine or placebo). The study center staff will contact you by phone 7 days after each study injection. |
Follow-Up Period
(about 2 years) You will visit the study center up to 6 times for study assessments after you have received the study injections. Additional visits may be required if you develop signs of COVID-19 during the study. |
Why is the AZD1222 COVID-19 VACCINE Study important?
There is currently no approved vaccine for COVID-19. In this study, participants will be randomly assigned (by chance) to receive 2 injections of either the investigational vaccine or placebo (4 weeks apart).
A placebo looks like the investigational vaccine but contains no active vaccine. There is twice as much chance of receiving the investigational vaccine than of receiving the placebo.
