Now I could be wrong and often am but I interpret it this way.Today if I am Double vaccinated and boosted all I need is do is provide proof of 3 shots to enter. Today double vaccinated only, require a test to enter. As of March 1 the double vaccinated do not need a test but I would imagine proof would be required. Now the next part is tricky, if you are 9 months past infection you also do not need a test to enter and I don't know how you would be able to substantiate that situation.
