Exciting news! 🚨 My new course: "Innovations in Immunizations: Epidemiology, Effectiveness, and Equity" will launch online as part of the 2026 McGill Summer Institutes in Global Health! I designed this course to meet the moment - we are facing truly unprecedented times...

Great reminder, @gregggonsalves.bsky.social! A friend who wants their friends to stay healthy is a very good friend in my book. Friends definitely don’t let friends face the fall respiratory virus season unvaccinated!! Please get your COVID and Flu shots, ASAP, friends!!

Thank you, @cidrap.bsky.social, for covering our new @nejm.org review of Covid-19, RSV, and influenza immunizations. Check it out: cidrap.umn.edu/covid-19/meta-analysis-covid-rsv-flu-vaccines-fall-provides-sea-data-showing-efficacy-safety

NEW @nejm.org: We synthesized 511 recent studies on Covid-19, RSV & flu vaccines for 2025-26. With federal advisory processes disrupted, clinicians & the public need rigorous, independent evidence synthesis. Here's what we found: 🧵 www.nejm.org/doi/full/10....

Check out our new paper @nejm.org. RSV, COVID-19 & Influenza vaccines continue to show consistent effectiveness & safety based on a review & synthesis of 500+ research studies👇! We worked hard to evaluate the evidence so you can be confident about getting vaccinated this fall!

Even as the anti-vax lobby erodes public trust, new evidence confirms that "immunizations against Covid-19, RSV, and influenza have shown consistent effectiveness & safety and are associated with a substantially reduced risk of hospitalization & severe disease" www.nejm.org/doi/full/10....

Congrats to @nicolebasta.bsky.social of the Department of Epidemiology, Biostatistics and Occupational Health for renewing her Canada Research Chair in Infectious Disease Prevention!

Serving on the Vaccine Integrity Project Scientific Team @cidrap.bsky.social alongside so many epidemiology/medicine/public health colleagues is an honor and a daily reminder of the commitment that so many of us have made to shining a light on the rigorous evidence we all need to protect our health.

A growing contingent of doctors say they are wary of federal health guidance under Robert F. Kennedy Jr.—and they are forming a parallel public-health universe.

Public health practitioners and researchers care about: 🧒People 🤝Communities 🩻 Physical Health 🧠 Mental Health 🌱 Well Being 💟 Equity …and so much more Those working in public health have dedicated their lives to service, so that everyone, everywhere can thrive.

"A week ago, on Aug. 8, a gunman attacked the CDC headquarters in Atlanta, firing nearly 500 rounds, breaking about 150 windows, and killing a police officer." - @colincarlson.bsky.social and @publichealthguy1.bsky.social

This point isnt being made enough. Last week’s attack on the #CDC could have been a slaughter. www.statnews.com/2025/08/15/c...

Even if Congress continues to fund the National Institutes of Health at current levels, the Trump administration “is setting them up to fail,” a former official told Katherine J. Wu:

I haven't been very active on here, but would love to connect with colleagues new and old from #epitwitter #episky & beyond. Please come find me on linkedin! www.linkedin.com/feed/update/...

These are not just grants. This is thousands of people who devoted their lives and careers - taking pay cuts, working long hours, living with uncertainty - all for the chance to try to make people's lives a bit better for you and your loved ones. This breaks my heart.

🚨 2 WEEKS TO GO! #UKCVN2025 kicks off soon – the UK’s only adult vaccine research conference! 🌍 Hear from top experts like ‪Professor Nicole Basta, Dr Conall Watson & many more 🌟 📍 Cutler's Hall, Sheffield & online 🗓️ 11th–12th June Register now before it's too late 👉 ow.ly/8i2p50VOwF3

Great insight from Kathryn Edwards in @statnews.com The FDA is circumventing key roles and procedures for licensure and use of Covid vaccines www.statnews.com/2025/05/22/f...

📢 Data we've published today shows the positive impact of the #Flu vaccine last winter. The figures are encouraging, but many more could have been protected if more eligible people took up the free flu vaccine. www.gov.uk/government/n...

Great reporting on FDA's plans to strip Americans of the choice to reduce their risk of #COVID19 by restricting vaccine approvals. If you want to reduce your risk, getting vaccinated is still the safest option. @katherinejwu.com @theatlantic.com www.theatlantic.com/health/archi...

Looking forward to speaking at the UK Clinical Vaccine Network Conference @ukcvn.bsky.social #UKCVN2025 in June! Stop by and say hello if you'll be there #episky.

Some of the CDC's main channels for communicating urgent health information to the public have gone silent.

I talked to NIH officials, current and former, about what's been happening inside the agency since the Trump administration shut down their grantmaking pipeline in January. Their stories showed just how willing our new leaders are to break the law: www.theatlantic.com/health/archi...

A truly depressing article in #Nature listing of all the damage done to #science in the US by the Trump administration in just one month 💔 for so many friends and colleagues there #solidarityforscience 🧪 www.nature.com/articles/d41...

#ACIP, the expert panel that advises #CDC on vaccine policy, will not meet next week. #HHS, which never gave final approval for the meeting, per sources, suggests it will be rescheduled, but gives no date. www.statnews.com/2025/02/20/a...

🧵Who is opposing the Trump administration? I analysed 76 actions of the administration since inauguration and then searched for *meaningful* opposition to each. I grouped the types of opposition and considered what we can learn from both them & actions where opposition has been lacking 1/24

"The very fact that I am having to publish this anonymously in a country that has the right to free speech written into our Constitution is an indictment of what is happening." www.bmj.com/content/388/...

Because there's not enough going on: Arizona has found #H5N1 #birdflu in milk and it looks like yet another spillover from wild birds. www.statnews.com/2025/02/14/a...

#AskAnInfectiousDiseaseDoc For the next 24h ask me anything about infectious diseases and vaccines. I will try to answer your questions below. Answers are not medical advice, just information and education. I will try to do this periodically. Let's go!

A fantastic article by Dr. @gregggonsalves.bsky.social on the dangers we’re facing and a potential path forward 👇🏻

🧵"So this is how liberty dies..." Trump’s first 3 weeks have been a relentless flood of actions. It's incredibly hard to keep up. I’ve gone through 69 actions & mapped out the pattern - showing how they fall within 5 broad domains consistent with authoritarian states 1/9

New from me in @wired.com: Donald Trump's cabinet is full of conspiracy theorists who think COVID-19 is a bioweapon, and that the doctors and scientists who now report to them helped create it. Those scientists are worried about the coming military tribunals. www.wired.com/story/reveng...

Johns Hopkins officials said the NIH funding cut puts at risk approximately 600 current and ongoing clinical trials at Hopkins, including open clinical trials in cancer, pediatrics and children’s health, heart and vascular studies and the aging brain. www.thebaltimorebanner.com/education/hi...

“It is a misnomer to call these funds indirect costs. They are essential to the safe and ethical performance of research. The environment in which research is conducted is highly specialized and costly.” 🧪 Great editorial by @holdenthorp.bsky.social in @science.org

I’m genuinely struggling to articulate my horror at what is happening. These actions put Americans at risk. There is no rational benefit to these orders other than a continued attack on public health. www.washingtonpost.com/politics/202...

CDC employees have been ordered not to engage with WHO employees until they receive “further guidance”. “The work affected includes consultation about the makeup of influenza vaccines, which must be updated every year because of the constantly evolving nature of influenza viruses”.

BREAKING: The Trump administration has instructed organizations in other countries to stop disbursing HIV medications purchased with U.S. aid, even if the drugs have already been obtained and are sitting in local clinics. www.nytimes.com/2025/01/27/h...

To be CRYSTAL clear: this decision puts American lives & health at risk, in both the short and long term. We wouldn’t have made Covid vaccines so quickly, stopped Ebola, escaped SARS1, or much more, if not for WHO partnership This is a bad idea for the *US*- never mind for the rest of the world🛟

“the immediate halting of funding to the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR), including a stop-work order for existing grants and contracts, places millions of lives in jeopardy”, @iasociety.bsky.social writes in a statement. #IDsky 🧪

Every week, I check the CDC's Mortality and Morbidity Weekly Report. This week for the first time in its 60 years it was not published on schedule. American healthcare workers all over the country are less informed about health crises that affect their patients. CDC led reports matter a 🧵
