mRNA vaccines induce human cells to produce viral spike proteins
the verdict
SUPPORTED
the evidence backs this
confidence 84/100
Multiple peer-reviewed studies and clinical analyses confirm that mRNA vaccines deliver genetic instructions that cause human and mammalian cells to successfully produce viral spike proteins, triggering the desired immune response.
