Prisma is now doing Phase 1a vaccine appointments via MyChart (as opposed to via VAMS). Per the government officials liaison, the web link below is the best way for individuals to know the latest and greatest around Prisma Health vaccine location hours, walk in availability, etc. In the screenshot, you’ll see they’re currently taking walk-ins for second doses at the K-Mart location. You can see it was last updated today at 10:26 AM. Prisma offers the Pfizer vaccine. You must have two shots of the same vaccine (i.e. 2 Pfizer vaccines). Second doses should be administered as close to the original window as possible: between 17-21 days from the first dose. However, the window has been extended to 42 days. They will not administer the dose early because it won’t be effective. For second dose walk-in appointments, you just bring your vaccine card to the K-Mart and let them know you’re there for your second dose. Just check the website first to ensure they’re doing walk-ins. They will continue to do walk-ins as vaccine is available. https://lp.prismahealth.org/prisma-health-vaccination-sites/
