I read this as them realizing they will lose the vaccine battle so they are laying ground work to explain it disappearing when the new test comes out and still at least half the country is not vaccinated. They need some magical way to try and explain it going away. The primary plan was the vaccine but too many people awake to vaccinate enough. This all combined with Israel doing the world a favor and putting everyone on notice showing a 85% vaccinated country is the one setting records for daily new cases.
