Spike proteins are harmless: According to the US Centers for Disease Control and Prevention (US CDC) and Meedan Digital Health Lab, spike proteins produced by COVID-19 vaccines are harmless. 

What are spike proteins? According to the US CDC and Yale Medicine, spike proteins are “crown-like spikes” on the surface of coronaviruses like SARS-COV-2 that cause COVID-19. The mRNA vaccines against COVID-19 instruct the body to create copies of these proteins to teach the body how to defend itself against the actual virus.

  • Why are spike proteins needed? The US CDC said on their website that the presence of spike proteins in the body triggers the immune system to produce antibodies to fight spike proteins that it thinks are an infection. 
  • When an actual infection happens, the US CDC said that the body will know how to fight the actual virus having learned how to fight it using spike proteins.
