A month ago, I defended my PhD! I am now seeking a postdoc position in host-microbe interactions (preferably Gram-negative ESKAPE pathogens but am open to others). Thankful to @doerrlab.bsky.social and others for the support 🫶🧬🧫🐭

Warren: "He can stand there, smile at you and say, 'anybody can vaccinate their kids who wants to,' but he literally could bankrupt the vaccines manufacturers with the power he will have. And since he's got a financial incentive to do that, we cannot trust him in that job."

Are these health interventions evil too, according to anti-vaccine activists? Scientific progress doesn’t stand still. And it definitely isn’t a conspiracy. Read more about this at ImmunoLogic ⬇️⬇️ news.immunologic.org/p/more-vacci...

More vaccines exist today than 40 years ago. That's a good thing.
Every new vaccine means fewer deadly diseases and more lives saved—that's the ultimate goal of scientific progress.

Just a reminder that in 2019, RFK Jr.'s anti-vaccine misinformation campaign helped cause a measles outbreak in Samoa that killed 83 people, mostly kids. Do you really want him to lead the Department of Health and Human Services?

My introductory post: I am a PhD Candidate and will be on the job market for a postdoc or research scientist position sometime in 2025. I currently study Gram-negative ESKAPE pathogens and their responses to antibiotics and the host innate immune system. Glad to be here!
