I have done well with the booster. Yay! Now, like I said earlier, hope I don't get my grandsons cold. . Interesting thing. Since I got my vaccine shots in March, I haven't had a cold. What?

Hope it's true findings! ............. https://www.hopkinsmedicine.org/new...w-covid-19-strains--and-maybe-the-common-cold
