    Always grateful for 's honest and nuanced writing and how it helps me wrangle with complex issues. I struggled a lot with getting my booster and although I got it, I am still very angry about vaccine inequity and privilege.

    A sketch to explain how a new variant may appear milder even with no change in underlying virulence. This can occur because, when calculating the fraction of cases that are severe, the denominator now includes many re-infections that had previously been averted. A thread. 1/8

    always important to remember that immune responses also evolve!

    Replying to @KatherineJWu
    The virus evolves, but so does the B cell response. Boosters push antibody maturation which helps antibodies better recognize antigenic variation. This was part of our reasoning, even early on.

    yes, we do know that actual SARS-CoV-2 infections can futz with immune responses in vivo, but that’s not what the data this week is addressing

    antibodies, take a seat (just for a sec, we’ll be back to you soon)

    This was a wonderful piece by . And in light of recent news, it's important to remember that the immune system is incredibly dynamic and contains many different cells with their own unique contributions in combating pathogens.

    2/2 the virus was shifting its offense. it was threatening to come at my community with a battering ram. so I shored up my already-super-strong defenses so I'd be really to meet it.
