• SPIKEVAX^® is the first updated COVID-19 vaccine authorized in Canada for 2024-2025, offering a timely solution to help protect Canadians this fall and winter season.
• Moderna will promptly begin delivery of updated COVID-19 vaccines to the Public Health Agency of Canada, so there is robust supply available in time for provincial and territorial vaccination campaigns.

CAMBRIDGE, MA / ACCESSWIRE / September 17, 2024 / Moderna Inc (Nasdaq:MRNA) today announced that Health Canada has authorized its updated COVID-19 vaccine, SPIKEVAX^® KP.2 variant, to help prevent COVID-19 in individuals six months of age and older. Moderna's updated COVID-19 vaccine targets the KP.2 sub-lineage of SARS-CoV-2. With vaccines ready, Moderna will begin delivery of updated doses to the Public Health Agency of Canada, ensuring supply is available in time for provincial and territorial vaccination campaigns.

"As we face another critical season in the fight against COVID-19, we remain steadfast in our dedication to delivering innovative solutions that help protect communities," said Stéphane Bancel, CEO of Moderna. "The authorization of our updated COVID-19 vaccine by Health Canada ensures that Canadians have timely access to the latest vaccines, helping them to stay protected during the upcoming fall and winter months."

Receiving the most recently updated COVID-19 vaccine is expected to provide a better immune response against circulating COVID-19 strains compared to earlier vaccines. It is especially important for those at increased risk for COVID-19 infection or severe COVID-19 illness.¹

"With the recent increase in COVID-19-infections,² staying up to date with your COVID-19 vaccination remains one of the best ways to help protect yourself from severe illness," said Dr. Shehzad Iqbal, Country Medical Director, Moderna Canada. "Canadians are encouraged to speak to their healthcare providers about receiving an updated 2024-2025 COVID-19 vaccine alongside a flu shot this fall."

Health Canada's approval is based on a combination of manufacturing and pre-clinical data, as well as previous clinical, non-clinical, and real-world evidence supporting the efficacy and safety of Moderna's COVID-19 mRNA vaccines.

Highlights for Fall 2024-2025 KP.2 Variant Updated Vaccine:

• The updated vaccine is based on consultations with the Public Health Agency of Canada that the preferred composition for the 2024-2025 updated COVID-19 vaccine is a monovalent KP.2.

• SPIKEVAX^®will be available in one presentation, allowing adult and pediatric doses to be drawn from the same multidose vial.

• The National Advisory Committee on Immunization (NACI) recommends that anyone not vaccinated or without a known COVID-19 infection in the past three months may receive an updated dose, with a focus on safeguarding vulnerable individuals.¹
