T-cells from common colds can provide protection against COVID-19 - study

LONDON : High levels of T-cells from common cold coronaviruses can provide protection against COVID-19, an Imperial College London study published on Monday has found, which could inform approaches for second-generation vaccines.

The study, which began in September 2020, looked at levels of cross-reactive T-cells generated by previous common colds in 52 household contacts of positive COVID-19 cases shortly after exposure, to see if they went on to develop infection. "We found that high levels of pre-existing T cells, created by the body when infected with other human coronaviruses like the common cold, can protect against COVID-19 infection," study author Dr Rhia Kundu said.

Current COVID-19 vaccines target the spike protein, which mutates regularly, creating variants such as Omicron which lessen the efficacy of vaccines against symptomatic infection.

Well Covid is a coronavirus, as is the common cold, so this makes perfect sense. Also means we will probably never find a cure unfortunately.

Hahaha! Yes, some of us knew this a very long time ago. But you go right ahead with 2,3 or 4 jabs!
