Consumer Information

This information was provided by the drug’s manufacturer when this drug product was approved for sale in Canada. It is designed for consumers and care givers. It is a summary of information about the drug and will not tell you everything about the drug. Contact your doctor or pharmacist if you have any questions about the drug.

What the medication is used for

COVIFENZ is a vaccine used to prevent COVID-19 caused by the SARS-CoV-2 virus. COVIFENZ can be given to people from 18 to 64 years of age.

What it does

COVIFENZ works by helping your body to protect itself against COVID-19 by producing both antibodies and immune cells that recognize the virus, helping to prevent you from getting COVID-19 entirely or limiting how sick you become.

COVIFENZ is made of proteins in the form of Virus-Like Particles (VLP) from plants that produce these particles. The VLP in COVIFENZ looks like the SARS-CoV-2 virus to your immune system. COVIFENZ does not contain the virus that cause COVID-19 so you cannot catch COVID-19 from this vaccine.

As with any vaccine, COVIFENZ may not fully protect all those who receive it. Even after you have had both doses of the vaccine, continue to follow the recommendations of local public health officials to prevent spread of COVID-19.

When it should not be used

You should not receive COVIFENZ if:

  • you are allergic to any of the ingredients in this vaccine (see What the medicinal ingredient is or What the non-medicinal ingredients are)
  • you had an allergic reaction after a previous dose of this vaccine
  • you have any symptoms that could be due to COVID-19. Talk with your healthcare professional about your symptoms and getting a COVID-19 test. Your healthcare professional will advise you when you are able to receive the vaccine.
What the medicinal ingredient is

The AS03 adjuvant used with COVIFENZ makes the immune response stronger and contains naturally occurring molecules (squalene and vitamin E) plus an emulsifier (polysorbate 80) and phosphate buffered saline. The vaccine does not contain any live viruses, egg proteins, preservatives, or human-derived materials.

What dosage form it comes in

The mixed vaccine is a whitish to yellowish homogeneous milky liquid emulsion in a multidose vial. Each dose is 0.5 mL and contains 0.25 mL (3.75 mcg) of virus-like particles (VLP) SARS-CoV-2 spike protein, adjuvanted with 0.25 mL of AS03.
