I haven’t noticed a huge change to my Twitter experience, but it might be analogous to the apocryphal boiling toad - hard to notice when change is so gradual. At worst, a rightward creep that’s easy to lessen with judicious use of the block function
One thing that can’t escape my notice: Mandy K Cohen, the Director of the CDC, has posted some rightfully pro-COVID vaccine tweets. One such here:

The comments skew at least 10:1 anti-vax. I don’t remember this being so clearly negative in the past.
As an aside, I got the most recent COVID booster on Wednesday, with zero side effects so far other than a slightly sore arm. I’m generally pretty healthy, but at 74 I can’t deny I find myself in a high risk demographic, and I want to try to tilt the odds in my favor as much as possible.
