On this MLK Day, we must commit to eliminating health disparities. The 1st step to that is measuring and tracking disparities. Towards that, we've put together a dashboard to track geographic and demographic disparities in US COVID-19 vaccination: vaccinetracking.us (1/)
Denominators matter. So, we aim to track vaccination coverage (as a proportion of population size)for total populations & racial, ethnic + age groups. Tracking vaccination coverage will allow us to track our path to herd immunity, and to quantify inequities in vaccination (2/)
Geographic patterns of vaccination coverage are key to reaching vaccine herd immunity goals. Our goal is to include county-level data for as many states as make that data available (currently only 8). We will update the dashboard as more data becomes available. (3/)
Systemic racism is already on display in the COVID vaccination data. For example, 4 times as many white Pennsylvanians have been vaccinated as Black Pennsylvanians (after correcting for population sizes). (4/)
Transparency in vaccine uptake is key to removing these disparities, but only a fraction of US states are currently reporting vaccination by race. We will update the dashboard with more data on vaccination by race/ethnicity as it becomes available. (5/)
Big shoutout to @AlexesMerritt and Andrew Tiu @Georgetown for their hard work putting this together!
We're a small team, but would be happy to take any feedback and will do our best to incorporate it.

There has been much discussion recently about herd immunity, and the impact of heterogeneity on herd immunity. A thread. (1/)
First, I want to reiterate the point made so articulately by @nataliexdean and @CT_Bergstrom: Natural herd immunity is not a goal we should be striving for. Trying to reach the end of this pandemic via that path will lead to mass deaths. (2/)
But understanding heterogeneity in COVID-19 transmission is important as it'll help to optimize social distancing and (eventually) vacc strategies. A recent thread by @mlipsitch also discusses how heterogeneity may reduce herd immunity thresholds. (3/)
