The availability of COVID-19 vaccines in Kentucky continues to increase week by week, and that's getting the commonwealth closer to a time when the shots will be available to the general public.Gov. Andy Beshear has been updating the state on the progress of upping weekly allocations from the federal government. Since President Joe Biden took office, shipments have increased across the country and now the administration is promising that all adults will have access to a COVID-19 vaccine by the end of May.Back in Kentucky, the commonwealth only recently moved into Phase 1C this week. While allocations have increased almost on a weekly basis, shipments haven't reached the level where the state can beginning opening up sites to more of the general public.Beshear said in an update Tuesday that Kentucky will receive more than 98,000 new COVID-19 vaccine doses this week, but there are no plans to move away from prioritizing residents 60 and older at this time. Phase 1C also includes residents 16 and older with underlying health conditions and all essential workers.Phase 1C will be the state's biggest undertaking yet before opening up to the general public. It's also unclear how the state will prioritize essential workers.Some of the boost in vaccine supplies come from the FDA approval this week of Johnson & Johnson's COVID-19 vaccine. The vaccine has been touted as a game-changer because it's single-dose and doesn't require special storage.While progress still needs to be made, Beshear has continued to remain optimistic about the state's efforts to get vaccines to all residents."The timeline when anybody who wants a shot can get a shot keeps moving up, keeps getting better," Beshear said.Over the past few weeks, Kentucky has been building a network of regional vaccination sites -- that will also work with local vaccination centers -- in an effort to have capacity ready for when more of the general public can begin receiving vaccines.
