This repository aims to support Canadian transfusion medicine health care professionals during the COVID-19 pandemic. It will be updated regularly as new information is available. In addition, the public and donors can learn more about how Canadian Blood Services is responding to COVID-19 by visiting blood.ca/covid-19.
The National Emergency Blood Management Committee meets regularly to review the supply of blood components and products during the pandemic and make inventory advisories.

Why getting a COVID-19 vaccine shouldn't stop you from donating blood. Individuals who have been vaccinated with any of the COVID-19 vaccines approved for use in Canada are still eligible to donate blood. To find out more about how Canadian Blood Services made this decision to not defer donors who have been vaccinated, read our blog post.

In the past few months, Canadian Blood Services has received several inquiries from physicians asking about data on SARS-CoV-2 binding and neutralizing antibodies in plasma-derived immunoglobulin products. This FAQ shares available evidence about SARS-CoV-2 antibodies in immunoglobulin products and includes information provided by immunoglobulin suppliers.
Patients may have concerns related to the safety of transfused blood or blood products collected from donors who have received a COVID-19 vaccine. If your patients have these concerns, our FAQ for health professionals may help you in informing their decision making. Information on this topic for the public can be found on Canadian Blood Services’ website at COVID-19 vaccines and blood donation.
Health-care workers who handle fresh blood components from Canadian Blood Services (i.e., red blood cells, platelets, plasma) may have questions about whether accidental exposure to these products puts them at risk for COVID-19. Read our FAQ that summarizes evidence supporting the view that the SARS-CoV-2 virus is not transmitted through blood and also provides links to other related guidance documents.

Effects of the COVID-19 pandemic on supply and use of blood for transfusion: Stanworth et al. (July 2020, The Lancet Haematology). COVID-19 has brought major implications for blood transfusion practices: uncertain demand patterns, reduced donations and loss of staff. This paper synthesizes studies that address the transfusion chain and provide guidance during times of potential or actual shortage. Dr. Mindy Goldman, Medical Director at Canadian Blood Services, is one of the study’s authors. For more about the study, visit the R.E.D. blog.
An article by Yazer et al. (May 2020, Vox Sanguinis) surveyed 12 centres from around the world (including Canada) about how hospital-based transfusion services have responded during COVID-19, including sample handling, pre-transfusion testing and issuing of blood products. See Table 2 in the article for a summary of respondents’ answers.
Recorded webinar: Application of SARS-CoV-2 Serological Assays for Monitoring the Epidemic and Qualification of Donors and Plasma for Use as COVID-19 Convalescent Plasma (Dr. Michael Busch, MD, PhD, Director, Vitalant Institute; Professor of Laboratory Medicine, UCSF).

All three national clinical trials examining COVID-19 convalescent plasma as a potential treatment option for COVID-19 patients (CONCOR-1, CONCOR-KIDs, REMAP-CAP) have discontinued patient enrolment. On Friday, January 29, 2021, the CONCOR-1 trial's independent data safety monitoring committee determined that the study is unlikely to demonstrate a benefit of convalescent plasma even if more patients are enrolled. The CONCOR-1 study team is in the process of completing the follow-up data for all enrolled patients and will release the final study results once the complete data set is available.
