“That is the real goal of any researcher,” said Dr. While this constant stream of new information can make things difficult when making public health decisions, it has been rewarding for researchers to see their efforts translate into clinically relevant findings. They began recruiting paramedics less than 10 months ago, but researchers continue to provide data in real-time to the CITF to determine if there are implications for policy decisions. Tracy Kirkham and Paul Demers from the University of Toronto. David Goldfarb, clinical associate professor in the department of pathology and laboratory medicine at UBC and medical microbiologist and infectious disease specialist at BC Children’s Hospital and BC Women’s Hospital and Health Centre, as well as Drs. Study participants are enrolled in the larger COVID-19 Occupational Risks, Seroprevalence and Immunity among Paramedics (CORSIP) project, a national study examining how the pandemic has impacted paramedics. Informing immunization strategy decisions Grunau.Īlthough measures of immunity are correlated with the risk of contracting COVID-19, this study did not assess actual breakthrough infections. “This longer interval strategy enables early access to first doses in the population and ensuring the best protection possible with the two-dose series,” added Dr.
Widening the recommended vaccine dosing interval has the potential to lead to a stronger long-term immune response in individuals and will also facilitate faster community-level access to the first vaccine dose. These findings have implications for the ongoing global vaccination effort, as half the world’s population has yet to be vaccinated. Although antibody levels are only one way to measure the body’s immune response, they play a very important role. MRNA vaccines include the Pfizer-BioNTech Comirnaty vaccine and the Moderna Spikevax vaccine. “We found significantly higher levels of antibodies in individuals who had longer vaccine intervals, and this was consistent regardless of which mRNA vaccine was administered,” said Dr. The peer-reviewed study compared blood test results from a total of 186 paramedics, some of whom were vaccinated within the earlier recommended interval of less than four weeks, and others who received their second doses after six to seven weeks.
