By Maryanne Demasi, PhD

Spike proteins on the surface of the SARS-CoV-2 virus are responsible for the pathogenesis of COVID-19.

There is a concern however, that spike protein in the body after vaccination is “toxic.”

To address these concerns, I spoke with vaccine developer, Professor Nikolai Petrovsky from Flinders University in South Australia. He has developed a protein-based vaccine called COVAX-19 (or Spikogen) which has received emergency use authorisation in Iran. 

He says that the spike protein in protein-based vaccines (Novavax/COVAX-19) is markedly different from that generated by gene-based vaccines (Pfizer/Moderna/AZ).

Is spike protein “toxic”?
