Yup. And up here in Canada, they are now doing a study to determine if it is alright to get a dose of one "brand" of vaccine and your second dose of another "brand." You know- just in case the one that you got the first time is not available. No, I'm not joking.
Sheesh, no wonder people are freaking out, too much like "shut up and take your medicine". However I saw a story this morning about how, just like we did, Canada is reminding itself of poorer nations and looking to donate vaccines so they must have a glut somewhere. Altruists are as likely to run amok with the self-justifying as the skeptics are.
