If the new variant picked up a piece of a common-cold coronavirus, does it means that: - You are better protected against Omicron if you caught the "right" cold - An Omicron infection (or maybe a vaccine) can protect against some common colds - As a last resort, deliberately infecting people with HCoV-229E will help - We should include all the endemic coronaviruses in our vaccines I have a feeling that all the answers are "no", but I just enjoy the idea of having some common cold viruses take collateral damage.
