Reacción a "Reaction to early laboratory data on how antibodies respond to the omicron variant"

The definitive answer will come from the comparison of the evolution of the infection in vaccinated and unvaccinated individuals. As the T-cell response will be at least partially conserved, I think we already know that the vaccines maintain responses against the variant and will probably be sufficient to maintain their objective of preventing severe disease and significantly reducing hospitalisation.

It is to be expected that the omicron variant will have a spectrum of protection similar to the other variants, since this protection is not so much quantitative (it may be less in number of lymphocytes) but qualitative (effect or non-effect) that can be explained by the immunological memory that will exist.
