The US is not Denmark. Denmark is not the US. The Danish immunization schedule is not adapted for the realities of the American Healthcare system and population. Let me explain. This is a long thread so buckle up 🧵

This is a reminder of how much it matters that pediatricians, public health specialists, scientists and members of the public who care about vaccines and science based recommendations continue to speak up. Many voices break through. www.politico.com/news/2025/12...

There have been at least 4.6 million illnesses, 49,000 hospitalizations, and 1,900 deaths from flu this season so far. There is a lot of flu out there. Getting the flu shot prevents hospitalisations and death! Please get your flu shot it id not too late.

Not recommending vaccines on a national level will harm children. Deferring all decision making to doctors while also systematicslly undermining everything that doctors recommend harms children. This is a deadly policy change. www.washingtonpost.com/health/2025/...

News flash humans are full of💩 and E coli. Even mandating a bowel prep prior to flying into the US could not rid our guts of the E coli who live and thrive there rent free 🤷🏽‍♀️

I am glad to see large media outlets reporting on this. Hopefully it shames the researchers into not continuing with the planned study or at minimum making sure ALL children in the study receive the birth dose of the HepB vaccine. www.science.org/content/arti...

The planned hepatitis B birth-dose trial in Guinea-Bissau raises serious ethical concerns. Withholding a proven, life-saving vaccine from newborns to answer speculative questions is an absence of equipoise with real downstream harms for trust in vaccines. bktitanji.substack.com/p/how-unethi...

This is unethical scientific exploitation through "research" on vulnerable populations that will cause harm and will be written about and taught in ethics courses in years to come. This study would not be approved by any IRB in the US or in Europe. African children deserve better.

5 things I will be watching closely in global public health in 2026: 1).US vaccine advisory chaos and outbreaks 2).Mpox recombination, evolution and endemic spread 3).Global HIV, TB, and NTD resurgence 4).Global surveillance amid funding cuts to CDC and WHO 5).Continued H5N1 mammalian adaptation

Ethiopia is responding to its first documented outbreak of Marburg virus disease (MVD). As of Dec 16, 14 confirmed cases have been reported in the South & Sidama regions, with 9 deaths and 5 recoveries. Small numbers, but a high fatality rate. reliefweb.int/report/ethio...

Lyme disease DID NOT come from a lab. HIV DID NOT come from a lab. These claims are unsupported by evidence, erase well-established science, and trivialize the suffering of millions and the work of scientists who have spent decades fighting these diseases.

Very sad to see the American Academy of Pediatrics lose vital funding support from HHS. This feels retaliatory in response to their stance defending Science and vaccines to protect children. When your kid is sick remember pediatricians treat them not RFK. Jr www.washingtonpost.com/health/2025/...

Without extension of the healthcare tax credit at least 4.5M Americans will lose healthcare coverage in 2026! I am here to tell you that your local emergency room CANNOT absorb the primary care for these individuals. This ⬆️ burden on hospitals will affect healthcare for everyone even the insured!.

As measles rages in S Carolina notice that those responding to this outbreak on the frontlines are pediatricians, family med practitioners, nurses and local public health officials. Not the wellness influencers and podscasters who discourage vaccination. Arsonists NEVER put out fires they start

That's a wrap for this year. As always thank you all for the thoughtful questions. I can't believe I have kept this going for 9 months! We are running it back in 2026. This thread is officially closed for new questions but you might find answers to your questions by reviewing 😊.

"A causal link between mRNA vaccination and excess long-term mortality appears highly unlikely." bit.ly/4q3rGDw

A much needed reminder in these times. 🧡

It's that time again. For the next 24h, drop any infectious disease and/or vaccine-related Qs in response to this post, and I will do my best to answer them. Responses are for information only & NOT medical advice. Can't believe it's the last one of the year. #AskAnIDDoc December 2025 edition.

Measles cases in the US: 2020 - 13 cases 2025 - 1912 cases so far and 3 deaths This is a 147x increase. There's no spin DHHS can put on this explosion of measles cases that will make this justifiable or acceptable.

Antisemitism is vile and should be condemned and rejected ALWAYS. No one should be targeted for their religious beliefs or because the belong to a particular ethnic group. What a horrible tragedy. apnews.com/photo-galler...

Another day. Another mass shooting. Watching students at Brown who survived high school mass shootings reliving a similar horror in college is heartbreaking. The lack of gun control has failed an entire generation of children, some now adults. My heart goes out to the families grieving tonight.

Just your daily reminder that the occurrence of frequent uncontained measles outbreaks in a country is not a flex, it is a marker of under development and a failed public health system.

Journal editors, please by default make sure you are extending review times in the month of December. Asking reviewers to return comments in 7-10d does not take into consideration the competing demands on reviewer's time at year's end. Especially given that the task of reviewing is fee labor.

The WHO expert group reaffirmed what is already known: There is no link between vaccines and autism.

One thing I enjoy about ID consults is you can never predict what golden nugget of history you would get from asking a relatively benign question. Today's classic Me: Tell me about your cats? Patient: Well they are cute but they have all been having diarrhea for the past month Me: Tell me more📝🤓

I am currently on ID consult service. I saw my first severe case of post influenza staphylococcal pneumonia of the season today - very sick patient admitted to the ICU. Every patient I have seen so far admitted with influenza this week is unvaccinated. The vaccines keep you out of hospital! Get 💉💉💉

Expertise STILL matters listen to scientists, public health experts and physicians for you vaccine recommendations. www.youtube.com/shorts/4wnNy...

I'm an Infectious Diseases Doctor. Our Pipeline of Experts Is in Distress. Had the opportunity to share my reflections on the challenges the ID specialty is facing on. @medpagetoday.com #IDSky www.medpagetoday.com/opinion/seco...

Health misinformation kills and its only getting worse. "Court records show the couple told investigators they relied on online videos and posts that warned against vaccines, infant medical treatments and even common medicines such as Tylenol."

A recombinant strain of mpox virus has been isolated from a patient in the UK containing fragments of clade I and clade II virus. Recombination occurs when two strains of virus infect a cell. These events tend to be rare but are well described in poxviruses. www.theguardian.com/world/2025/d...

The post thanksgiving travel influenza spike is here. Flu is all the way up in hospitals abd clinics. Later up on protection. Get your vaccine ASAP Wear a mask 😷 Ventilate/improve airflow in your indoor spaces. Stay home from work if you are sick.

Because the vaccine prevents chronic hepatitis B for which there is no cure and the lifelong treatment costs more than a single birth dose of the vaccine. Insurance companies recognize this is a no brainer. Brought to you by prevention beats treatment any day. www.cnn.com/2025/12/07/h...

In a moment of folly I decided to look up tickets for world cup games, you know as one does when a big sporting event is coming to your city. Beloved the resellers have taken over. These are ticket prices for group stage games on stubhub! My couch and TV will have to do because this is obscene.

A sad sad story and your reminder that rabies can have a very very long incubation period up to over a year. www.nytimes.com/2025/12/06/h...

Senator Bill Cassidy is a hepatologist, he confirmed a health secretary who is overseeing the come back of hepatitis B related cirrhosis and liver cancer. That legacy is a choice.

France is reporting two cases of MERS in two individuals who recently returned from the middle east. Both remain i hospital. MERS is caused by another coronavirus with spillover events occurring from usually from contact with camels. www.cidrap.umn.edu/mers-cov/fra...

The #ACIP just voted to harm children. What a sad day.

This remains one of the most disturbing stories of the year. A 1st trimester fetus incubated in a dead woman's body against the will of her family until a very early term birth when the corpse could no longer sustain life. www.cbsnews.com/atlanta/news...

Excellent reporting by @apoorvanyt.bsky.social . The vote was once again delayed...because there is no evidence to support that voting to eliminate the birth-dose of hepatitis B vaccine is right or in anyway justifiable. www.nytimes.com/2025/12/04/h...

A picture is worth a 1000 words. The birth dose of hepatitis B vaccines in the USA eliminated perinatally acquired hepatitis B infection from over 20,000 cases a year before the vaccine was introduced to <20 cases a year. The gaslighting by the current members ACIP is obscene, unethical and cruel.

The ACIP meeting sounds like an anti-vaccine convention.

Congratulations to the 272 physicians who matched into adult infectious diseases and the 44 who matched into pediatric infectious diseases this year. Over 50% of programs went unfilled, marking a very challenging match year for ID. The current hostile sentiment towards ID is not helping recruitment.

I really enjoyed reading this. A fascinating new natural-experiment study in Cell adding to the evidence that shingles vaccination may have cognitive benefits beyond preventing zoster. i.e. may slow dementia progression. www.cell.com/cell/fulltex...

The #ACIP meets tomorrow to assault on vaccines that protect children. They will be debating the birth dose of the hep B vaccine. I wrote about this previously but we cannot say it enough stopping the birth dose is unethical given the many benefits. bktitanji.substack.com/p/the-hepati...

GLP-1 agonists are great for obesity & other chronic health conditions e.g CVD but they do not seem to have any effect on the progression of Alzheimer's disease in humans despite promising observations in mouse studies. this is why clinical trials matter. www.nature.com/articles/s41...

The DRC has officially cleared the 42 day mark without new cases of Ebola in its latest outbreak which is now officially declared ended. Kudos to local authorities who made this possible and foreign partners and international organizations that supported the response. africacdc.org/news-item/eb...

In case you are wondering what being a federally funded researcher looks like these days: the shutdown required that NIH cancel over 370 peer review meetings, impacting the review of over 24,000 applications. As a result the percentage of applications discussed will be reduced from 50% to 30-35%.

Today December 1st is #WorldAIDSDay. I remember the millions who have died. I celebrate the transformative progress that has been made. I resolve as an HIV researcher and advocate to keep up the fight to end the HIV epidemic. Do you know you status? Get tested. Get treated. Get on PrEP.

6 years today the first COVID case was identified in a man in Wuhan marking the beginning of a global pandemic that changed the world. We are way less prepared today to face another pandemic than we were back then. This fact makes me sad.

A worthy read! www.linkedin.com/redir/redire...
