His argument is fallacious. He's saying that since there all other variants we're susceptible to the vaccine, it's unlikely that this one is. ...and goes on to list the high number of different markers the vaccines target. Unfortunately, vaccines largely target the spike proteins, and sequencing of omicron is demonstrating that every single protein marker on the spike is changed. Vaccines will likely have a very smal…
A study in Nature had previously shown that >= 20 amino acid mutations on the spike protein was sufficient to cause immune escape from the vaccine or previous infection, but that individuals who were both previously infected and vaccinated were still able to neutralize the mutant virus. [1] The omicron variant has >30 AA mutations on the spike protein, so it remains to be seen how effective vaccines are in response t…
Mainly because of the infection, not the vaccination. Infection trains your immune response to detect multiple factors of the virus, the mRNA vaccines are only for the spike protein which has considerable mutations in later variants like this one.
Arguably, traditional dead-virus vaccines might provide better long-term protection for this reason, but we went all-in on the new tech.
