Vaccine passports are the wrong answer to the question: “How do we get back to normal and restore our economy?” The correct answer is: “We end fears about this virus.” The way to do that is to work to ensure that all countries have vaccines, not to reinforce disparities.

Variants don’t help, but they aren’t the main cause of case acceleration. A failed public health response that permits uncontrolled case growth is. Countries have paused the spread of variants with public health measures. Vaccines are needed for long term protection.

We need to rethink the US's approach to testing. Performing >600,000 tests per day is pointless if it takes more than a week to get test results. We've technically expanded testing to include mild or asymptomatic infections, but functionally haven't.

Apparently some are still trying to dismiss growth in cases as artifact of increased testing. It’s not true. When positivity is surging it signals that increase in infection is outpacing increase in tests.

Given that Florida is now responsible for 20% of the country's #covid19 cases, it is worth pointing out that the state has dramatically scaled back on the covid data it reports. Cases reported 1x/week, no county deaths, no state testing #s .

Florida was one of the first to cut back to weekly COVID reports. Did it move too soon?

For example, if healthcare workers don’t wear masks socially outside work or in the breakroom it can undermine the estimate of overall effectiveness of their masking at work. It doesn't necessarily mean masks don't help protect individuals when they're seeing patients. 16/

If you cared about the kids of Baltimore City you’d be calling to close packed city bars where no one wears masks, instead of schools where everyone can be masked & vaccinated against serious illness. School closures cause generational harm. Bars drive transmission, not schools.
