You know with Scrotus inviting Xi, a 'foreign head of state', it sounds to me as if he's looking at his inauguration (which is usually very US-centric) as more of a coronation in which foreign monarchs/heads of state are routinely included.
I'm trying to think of other heads of state who might actually show up. Scrotus' besties Putin and Kim wouldn't set foot on US soil, nor would Erdogan whom Scrotus so greatly admires. Maybe he can get Assad to come. No no, he probably considers Assad a 'loser' since he was deposed so he doesn't 'rate' an invite.
On other matters, the suit to revoke the polio vaccine is just the opening salvo. I worry for those who don't have lifetime immunity to all the diseases we vax for. For some of those diseases, those who had vaccines don't often have lifetime immunity and if they start 'withdrawing' vaccines it will be a disaster as they won't be able to get boosters. Especially at risk are women who had the rubella vax and who are planning on becoming pregnant. My cousin had to get a booster back in the early 90s because her childhood immunity through vaccine had 'worn off'. TBH I'd urge anyone (male or female) in the US who didn't actually have the diseases we vax for to check with their doctor, get titre tests if needed and get those vaxxes ASAP.
DH and I had all the 'usual' childhood diseases because our childhoods were 'pre-vaccine' for most of them so we have lifelong immunity. We had the polio 'sugar cube' as well as the smallpox vax (yes, we're that old) which also confer lifetime immunity so we're good there. We're both up to date on Tetanus, covid, and flu. But we are planning to get whatever vaccines we need before 21 Jan. Hope for the best, get jabs for the worst.
