Our project’s aim is to learn more about the effectiveness, safety, and immune response in individuals with low or compromised immune systems
who have been vaccinated with the Pfizer-BioNTech or Moderna mRNA or Astrazeneca COVID-19 vaccines.
Interested in joining our study? We are currently recruiting the following participants from across Canada:
People aged 5 years and older who are either healthy or have primary immunodeficiency (inborn error of immunity) or have been on immunotherapy such as rituximab, ocrelizumab for medical conditions AND:
Have not been vaccinated but plan to be vaccinated against COVID-19, or
have received their first , second, third or fourth dose of the COVID-19 Pfizer/BioNTech, Moderna mRNA, or AstraZeneca vaccination, or
were fully vaccinated (two doses for healthy people and 3 doses for immunodeficient people) against COVID-19 less than 24 weeks ago
