New evidence reinforces booster doses of COVID-19 vaccine: Hamilton’s McMaster University
Published January 24, 2022 at 3:00 pm
Research out of Hamilton’s McMaster University provides evidence reinforcing booster doses of COVID-19 vaccines for the most vulnerable; including residents of long-term care homes, retirement homes, and assisted living facilities.
Researchers found that there was a robust immune response to a third mRNA vaccination and a greater capacity to fight infection compared to a two-dose series.
The findings are based on the blood tests of over 500 adult residents who received either Pfizer or Moderna as a third vaccine dose at least six months after their second shot.
This new data was published in the form of a research letter in the Journal of the American Medical Directors Association.
Two of the researchers behind this work, Andrew Costa and Dawn Bowdish, will share the findings as part of a panel discussion on Jan. 24, hosted by the COVID-19 Immunity Task Force.
Their work is a continuation of earlier research, which found low antibody response in one in five long-term care residents three to five months after their second vaccine dose.insauga's Editorial Standards and Policies advertising
