53: From Works In Progress: The Story Of VaccinateCA, by Patrick McKenzie (@patio11). The very beginning of rolling out COVID vaccines in California was plagued by political and logistical nightmares. Patrick McKenzie of Stripe and a few of his friends founded a group to try to break the logjam, and ended up saving thousands of lives. Highly highly recommended, both as a story about heroic altruism and as a look into how the political sausage gets made (or doesn’t). Don’t worry, there are juicy culture war parts.

Nuno Sempere, $50K, for disaster forecasting and response. Nuno runs Sentinel, a team of superforecasters which tracks incipient disasters (pandemics, wars, etc) and brainstorms pre-hoc and post-hoc responses. Their model for response are groups like VaccinateCA, a small team of Californians who noticed that the state’s COVID vaccine policy was disorganized and made a site that helped connect people with spare vaccination capacity. You can see their blog here. Nuno is an ACX Grants evaluator; due to conflict of interest, this grant is being covered in conjunction with an outside funder.
