KANSAS CITY, Mo. (AP) — As Kansas and Missouri prepare to open up vaccine eligibility to all adults, officials are working to win over skeptics of the COVID-19 shots. Kansas plans to open up vaccine eligibility to all adults on Monday, and Missouri is set to do the same on April 9. Health officials want to administer as many shots as possible quickly to build widespread immunity. Officials plan to step up their efforts to convince people to get the shots now. Already, there have been signs of some reluctance during earlier stages of the vaccine campaign.
