Study purpose and objectives

MOSAIC will be looking to find the answers to three questions:

  1. How safe and effective is a full COVID-19 vaccination if the first and second dose is 28 days apart compared to a schedule with the first and second doses are 112 days apart.
  2. How safe and effective is a two dose COVID-19 vaccine schedule when different vaccines are used for the first dose and second dose
  3. How long does protection from COVID-19 vaccines last in the above conditions

Eligibility

You can take part in this study if:

  1. You are 18 years of age or older.

  3. You are in good health, including if you have stable health conditions.
  4. You are not pregnant.
  5. You have a record of the first dose of the authorized COVID-19 vaccine you received and have not received the second dose yet, OR, you have not received a COVID-19 vaccine.

What will you be asked to do?

You will have 5 clinic visits and 2 telephone/email contacts if you are a vaccine naïve participant (have not received a COVID-19 vaccine) during a 12-month period.  The total time commitment is approximately 3-4 hours.

You will have 4 clinic visits and 1 telephone/email contact if you are a vaccine exposed participant (received your first COVID-19 vaccine from Public Health) during a 11-month period.  The total time commitment is approximately 2-3 hours.

You will also be asked to record a diary, where you will note information regarding your symptoms for the first 7 days after your vaccine, and to complete a paper questionnaire twice over the study regarding your opinion about the vaccines.
