A new study from Imperial College London shows the common cold offers better protection from Covid-19 than vaccines.
The study found that people with il-2 secretions (comes from having a cold previously) were less likely to become ill after being exposed to Covid-19. Put simply, the reason this provides protection is that the common cold is a type of coronavirus and provides a significant level of T-cells. The study did not indicate how long the T-cell levels would remain high after having a cold.
The vaccines only target the spike protein which is what mutates and is why we have seen a drop in efficacy after each variant runs its course. The vaccines are not targeting the ball that doesn’t change, only the spikes that change frequently. This study could help with future vaccine development to increase the efficacy through multiple variants.
