 We are hearing that ACIP is looking at the new formulation for the fall and going to be making recommendations on that. We do anticipate there will probably be a new formulation in the fall that will be updated to combat the latest COVID-19 variant. But even now, if you're not up to date with your 2023-24 shot, I would strongly recommend to go ahead and get it now and not wait for that new fall formulation. There will be opportunities to get that update later.
