With demand for COVID-19 vaccines in the US waning quickly, both individual states and the federal government are pulling out all the stops to try and convince as many American adults as possible to consent to being vaccinated. Some states have pushed promotions offering free money, free beer, and free doughnuts, among other offers. Oregon is even offering a $1 million lottery for which only the vaccinated are eligible.

As more states embrace these types of incentives, California just announced that it was hopping on the vaccination lottery bandwagon Thursday evening by offering 10 vaccinated residents  the chance to win $1.5 million each, Gov. Gavin Newsom announced Thursday, while another 30 residents will win $50K cash prizes.

The program is being announced as California struggles to boost its vaccination rate (while the national rate of adults who have received at least one dose has just passed 60%).

More than 288 million doses of the vaccine have been distributed across the US, but the daily rate for patients receiving both their first and second doses is slowing.

These types of initiatives are being rolled out across the US as rural areas see comparatively little demand when compared with urban areas.

Now that California is in the mix, 7 US states are offering the possibility of cash prizes for those who choose to get the vaccine. Prizes range from a daily $40,000 prize in Maryland to a $5 million jackpot in New York. Here's a rundown of what other states are offering. Another state, West Virginia, is offering savings bonds to all adults between the ages of 16 and 35.
