New York State has sponsored a smartphone app that
would tell a facility (convention hall, theater, bar, etc) your vaccination status
and about recent negative COVID tests.
USA Today has the story, by Karen Weintraub et al.
Other states would need to develop the same (by copying
the open source software) and states would need to recognize each other’s
info.
I understand that NYS waives the testing an quarantine
requirements for visitors two weeks after completing vaccination, for two+
months. I hope this will extend to
longer soon.
VOA News has a discussion of vaccine company trials
against variants, with special emphasis on Brazil’s which may be the most troubling; protection specifically against Brazil is
likely to protect against South Africa and several new variants in the US. But it will take several months to test new vaccines well enough to use, although we hardly have time for full phase 3 trials.
John Campbell discusses the concern that vaccines could
drive the virus to mutate more quickly, unless given to everyone very quickly (around
the world). Existing vaccines do seem
likely to prevent serious illness from variants with less likelihood of stopping
transmissible asymptomatic infection that can be passed to the unvaccinated.
