San Francisco Chronicle featured a study coauthored by Mireille Jacobson on why financial incentives to encourage vaccination may not work. “(T)his is not the road to getting to ‘herd immunity.’ It might be that these small incentives nudge a few people one way or another, but it’s really just not going to get us anywhere near where we hope to get … we’re not nudging our way out of this epidemic,” said Jacobson.
