Covid-19 ‘vaccine lottery’ schemes across 19 states had no noticeable effect on vaccination rates and may have squandered millions in tax dollars, according to newly published research that suggests the programs were a major flop.
Published in the JAMA medical journal on Friday, the pre-print study by researchers at the University of Colorado Denver showed that the links between vaccine lottery announcements and inoculation rates were “very small in magnitude” and “statistically indistinguishable from zero.”
