Health Canada’s Approval of FOCLIVIA ® (An Adjuvanted, Egg-Based A Strain H5N1 Pandemic Influenza Vaccine) Meets Key Requirement as Pandemic Partner

MONTREAL , March 23, 2021 /CNW/ — Seqirus, a world leader in influenza vaccines and pandemic response, announced today that following Health Canada’s approval of FOCLIVIA ® (adjuvanted, egg-based A strain H5N1 pandemic influenza vaccine), the Company is ready to fulfil its role in Canada’s influenza pandemic preparedness plans.

Seqirus Canada is an influenza pandemic vaccine partner to the Canadian Government through the Public Health Agency of Canada (PHAC). The contract requires Seqirus to be on standby to rapidly manufacture and deliver a large number of vaccine doses to help protect Canadians against the influenza strain identified by the World Health Organization (WHO) when an influenza pandemic is declared.

Health Canada’s approval of FOCLIVIA is a key requirement of this contract and further exemplifies Seqirus’ position as the only global vaccine company singularly focused on influenza. FOCLIVIA is approved for use in individuals six months of age and older if the WHO declares an influenza pandemic. 1

“The approval of FOCLIVIA demonstrates our commitment to Canadians by providing a vaccine that can be used in the event of an influenza pandemic,” said Gillian Stafford , Canada Commercial Director, Seqirus. “If the WHO declares an influenza pandemic, Seqirus will produce the FOCLIVIA vaccine to be delivered throughout the country as approved by Health Canada. The approval of FOCLIVIA means we can help protect more people in an influenza pandemic.”

Seqirus is a leading contributor to influenza prevention and preparation. An influenza pandemic is a global epidemic caused by the emergence of a new influenza virus to which there is little or no pre-existing immunity in the human population. 2 The WHO Global Influenza Strategy for 2019-2030 states that a severe pandemic can result in widespread social and economic effects, including a loss of national economic productivity and severe financial burdens on affected citizens and communities. 3

FOCLIVIA includes Seqirus’ MF59 ® adjuvant technology, which can help enhance and broaden the body’s immune response by inducing antibodies with broader affinity. 4,5,6 This adjuvant is an integral part of pandemic preparedness planning. It reduces the amount of antigen required to produce an immune response, increasing the number of doses of the vaccine developed so that many people can be protected as quickly as possible. 7,8

About Pandemic Influenza

As with seasonal influenza, pandemic influenza is a contagious airborne respiratory disease that is unpredictable and can occur in any age group or population worldwide. 3 The risk of influenza-associated morbidity and mortality is greater with pandemic influenza than with seasonal influenza because of little or no pre-existing immunity to the virus in the human population. 3 Four influenza pandemics have occurred over the past century, with the 1918 pandemic being the most severe in recent history, estimated to have killed up to 50 million people worldwide. 9 According to the World Health Organization (WHO), A (H5N1) influenza strain can cause severe disease and has a high mortality rate. If an influenza virus of pandemic potential were to become easily transmissible from person to person while retaining its capacity to cause severe disease, the consequences for public health could be severe, causing significant morbidity and mortality. 10
