How well do COVID-19 vaccines work in people with inherited and medication-related immune deficiencies?

$2.5M grant from COVID-19 Immunity Task Force to help Canadian researchers find out

Dr. Juthaporn Cowan“Our study will provide crucial data to help us protect people with immune deficiencies against COVID-19,” said Dr. Juthaporn Cowan. “It will also help us learn more about which compartment of the immune system is essential in the COVID-19 vaccine response, so that better vaccines can be developed in future.” People with inherited immune deficiencies have a greater risk of developing severe COVID-19 and may be less likely to respond to vaccines. People with multiple sclerosis, arthritis and other immune-mediated diseases may also be at risk because medications for these conditions often suppress the immune system.

Dr. Juthaporn Cowan, infectious disease physician and associate scientist at The Ottawa Hospital and assistant professor at the University of Ottawa, is leading a national study to investigate how people with these conditions respond to COVID-19 vaccines.

The research team aims to recruit 460 participants with inherited or medication-related immune deficiencies from twelve sites across Canada (in Ottawa, Montreal, Toronto, Halifax, Winnipeg, Edmonton, Calgary and Vancouver). Participants must be at least 12 years old and must be either planning to get vaccinated or already vaccinated (up to 24 weeks post second dose).

The researchers also hope to recruit healthy individuals over 12 who have not yet been vaccinated, but plan to be, as a control group.

The researchers will collect blood samples from the participants to study the body’s response to COVID-19 vaccines, including antibody levels and T cell response. Participants will also fill out questionnaires and be followed by health care professionals to assess any vaccine side effects.

“Our study will provide crucial data to help us protect people with immune deficiencies against COVID-19,” said Dr. Cowan. “It will also help us learn more about which compartment of the immune system is essential in the COVID-19 vaccine response, so that better vaccines can be developed in future.”   

The study was awarded $2.5 million from the Government of Canada through its COVID-19 Immunity Task Force. It is one of four grants awarded to researchers at The Ottawa Hospital to investigate the immune response to COVID-19 and vaccines.
