1/ I want to see the Biden administration refocus our attention on hospitalization & death.

We've been asking too much from the COVID vaccines.

The vaccines are excellent at preventing severe disease, hospitalization, & death.

with @CBS @CBSMornings' @TonyDokoupil
2/ You are 14x more likely to die from COVID if you are unvaccinated than if you are vaccinated:

1/ Why is it so hard 2 years into the pandemic to access rapid at-home COVID tests? Why are they still so expensive?

2/ IN ADDITION TO VACCINATION, we need to be testing, to identify who's contagious and needs to isolate so as not to infect others.

What can the Biden administration do to increase access to rapid at-home COVID tests?
with @PBS @NewsHour's @TheStephSy
3/ Here's what the Biden administration announced this week that it would be doing to scale up access to free at-home rapid testing:

1/ We've been asking too much from the COVID vaccines.

The vaccines are excellent at preventing severe disease, hospitalization, and death.

But the vaccines won't prevent all infections even with repeated boosting every ~6 months.

1/ @IHME_UW projects:
- 3+ billion Omicron infections over the next 3 months globally
- % asymptomatic infections will go from 40% to 90% (many will be missed)
- infection fatality rate 97-99% lower for Omicron than Delta
2/ If the @IHME_UW model is accurate, the US will likely hit at least 2000 COVID deaths/day, & possibly 3000 COVID deaths/day.

Last year, we peaked at ~3500 COVID deaths/day.

covid19.healthdata.org/united-states-…
3/ If the @IHME_UW model is accurate, the US will likely hit almost 1 million deaths from COVID by March 2022.
