MOSAIC Study

Help researchers understand the immune response to COVID-19 vaccines!

Why are we doing the study?

Data has shown the effectiveness of COVID-19 vaccines against severe disease up to 6 months after vaccination, however, there is some evidence of decreasing antibody levels in some population. Hence, the National Advisory Committee on Immunization (NACI) and BC CDC have recommended a third booster dose in certain populations. This study will answer the following questions:

• What is the effectiveness and length of immune response after receiving different COVID-19 vaccines for the first two doses?
• What is the safety and effectiveness if different COVID-19 vaccine products are used for the third dose?

Who are we looking for?

Healthy individuals 30 years of age and older who have received and have a record of their first two doses of an authorized COVID-19 vaccine.

What does the study involve?

The study involves four clinic visits at the VEC during a period of 12 months. Total time commitment is approximately 2-4 hours. You will receive one telephone/email contact from us. We will ask questions about your health at each visit.
