State-led vaccine lotteries didn't boost vaccination rates, study shows

Those state-led vaccine lotteries that cropped up last spring and summer did nothing to sway unvaccinated individuals to get inoculated against COVID-19, new research shows. 

A variety of prizes — including cash, trucks and guns — were dangled in front of vaccine holdouts to try to incentivize more Americans to get jabbed and better control the virus as vaccination rates plateaued in May. 

By the beginning of July, 19 states had announced large cash lotteries tied to the COVID-19 vaccine.
