The Times of Israel article is still just conjecture. The only data is a quote from their ex-virus Czar saying selective pressure ‘could’ lead to the emergence of a vaccine resistant variant.

We know conclusively that large unvaccinated populations do lead to the emergence of more virulent strains. We also know that mass vaccination reduces mortality significantly so it’s the best option available today.

An updated mRNA booster would undoubtedly be a good thing and I suspect it will come in the next year.
