Immunity from COVID-19 booster shots lasts significantly longer than from the primary vaccine series, according to a study from York University's Centre for Disease Modelling.

The study, using Canadian data, indicates the antibody half-life response extends from 63 to 115 days with booster shots.

Factors such as age, sex, and comorbidities influence the duration of the immune response, with older adults initially showing a shorter immunity period.

Controlling for comorbidities, age's impact on immune response was reduced, while males and people with asthma showed a slightly more robust immune response.

The researchers highlight the value of interdisciplinary research and potential future collaborations with the upcoming medical school at York University in 2028.

The NHS is currently administering booster jabs to specific vulnerable groups, with plans to prioritize individuals at the highest risk through scheduled appointments and walk-in sites using updated Pfizer or Moderna vaccines targeting various COVID-19 strains.
