Immune system T-cells can fight omicron COVID-19 variant, study suggests
Fox News
Immune system T-cell responses remain broadly robust against the omicron variant of coronavirus, according to researchers.
"Overall, given that most of the experimental T-cell epitopes known to be targeted in vaccinated and/or previously infected individuals [collectively, accounting for (about) 60% of the global population as of 25 December 2021] are unaffected by omicron mutations, our preliminary analysis suggests that the effectiveness of preexisting T-cell immunity will remain intact," the group said.
"T-cell responses alone, however, do not block infection and therefore do not prevent transmission. Thus, while the number of infections may rise considerably as a consequence of omicron’s ability to evade antibodies, robust T-cell immunity provides hope that, similar to other [variants of concern], the level of protection against severe disease would remain high."
