Managing Mixed Immunity
and Related Infection Risks
Friday October 6, 2023
Unwrapping the complexity and variety of factors affecting risk of acute and chronic impacts in the context of workplace prevention strategy
Researchers at McMaster University have found that rather than conferring immunity against future infections, infection during the first Omicron wave of COVID left the seniors they studied much more vulnerable to reinfection during the second Omicron wave.“We found that some individuals had normal immune responses after the first infection, while others had very low levels of protective antibodies, which we believe was one contributing factor to why they got reinfected,” says Dr. Dawn Bowdish, who is corresponding author of the study published in eClinicalMedicine, an open-access journal by The Lancet.The researchers urge people not to assume immunity from a prior Omicron infection and to remain vigilant to prevent further spread of the virus.“This research highlights the need for continued vigilance and underscores the importance of ongoing preventive measures against COVID-19, says Bowdish.
