Safety and immune response of a smaller matching booster dose of the Pfizer COVID-19 vaccine in a controlled follow-up trial

mRNA Technology Weekly Brief ↗PubMed ↗DOI ↗

Updated

Abstract

Reduced-dose primo-vaccination against COVID-19 demonstrated safety and immunogenicity.

  • Fractional booster dosing may maintain strong immune response and protection.
  • Reduced doses could result in fewer side effects, enhancing acceptability.
  • This approach may help conserve vaccine supplies.
