South African researchers examining how the body's immune system responds to the Omicron variant have identified that T-cells in people who have had the Pfizer vaccine continue to be robust in potentially protecting against severe illness despite Omicron's ability to evade other defences.

The research raises hopes that similar responses may be present with other vaccines and within unvaccinated individuals who have been infected with coronavirus.
