- The Novavax vaccine uses a telltale piece of the coronavirus: the notorious spike protein.
- All alone, the spike protein is harmless and can’t cause COVID-19.
- When your immune system encounters the lonely spike protein, it produces antibodies against it.
- This gives you protection against future COVID-19 infection.
Then, What is a protein subunit vaccine? Protein subunit vaccines contain harmless and purified pieces (proteins) of the virus, which have been specifically selected for their ability to trigger immunity. Protein subunit vaccines are already used for other diseases. An example of an existing protein subunit vaccine is the one for hepatitis B.
