Third dose of vaccine enhances antibody response, particularly among older adults

A CITF-funded study in preprint, not yet peer-reviewed, by Drs. Marc Romney (University of British Columbia), Zabrina Brumme and Mark Brockman (Simon Fraser University), demonstrated that a third dose of an mRNA vaccine significantly enhanced the magnitude and durability of antibody responses, including among adults over the age of 70, who remained COVID-naïve (those who were not infected with SARS-CoV-2).

Findings show clear advantages of Moderna vaccine for long-term care residents

A CITF-funded study in preprint, not yet peer-reviewed, led by Drs. Dawn Bowdish and Andrew Costa from McMaster University, showed that among residents of long-term care facilities, there was a lower risk of an Omicron infection when the person had:

  • Received three doses of Moderna or a combination including Moderna (vs. three doses of Pfizer);
  • Any fourth mRNA vaccine dose; and
  • Hybrid immunity induced by 3 vaccine doses and a SARS-CoV-2 infection in the 3 months prior to the beginning of the Omicron wave.
