It is irresponsible to haphazardly change vaccine recommendations without a solid scientific basis and transparent process. The commitment the U.S. has made to protecting children from vaccine-preventable illness and death must remain a top priority."

Adopting Denmark's vaccine schedule here in the US is a bad idea. Context matters.
Vaccine schedules are built for the countries they serve.

Parent and pediatrician here.

All vaccines are still available & recommended. Talk to your pediatrician for more info.

Know this: Even as our government shifts its recommendation language, I would never forgo the RSV, hepatitis A & B, or meningitis vaccines for my own kids.

Lots questions from parents & media after the tragic deaths of Rob & Michelle Reiner…

Addiction is a medical condition, and treatment works. If you're worried about your teen or young adult, you don't have to navigate this alone.

Specialists are available across the US (see ASAM.org & AAAP.org).

Mass. doctor says CDC's Hep. B vaccine decision was 'largely predetermined' Dr. Scott Hadland of MGH Brigham gives his take on the CDC panel's decision on hepatitis B vaccines for babies.

Every pediatrician I’ve spoken to is shocked & horrified.

The CDC’s reversal on newborn Hep B vaccination will harm kids.

The birth dose protects all babies from highly infectious Hep B, which can lead to lifelong disease & liver cancer.

HBV is safe & delaying past 24 hrs puts newborns at risk.

BREAKING: ACIP votes to roll back universal newborn HepB shot.

Dr. Meissner: physicians pledge to β€œdo no harm”, and warned, β€œThis will do harm.”

The birth dose prevents ~70% of early HBV transmission. When kids get HBV before age 6, 70-90% get chronic disease, and ~1 in 4 go on to liver cancer.

This has big implications for clinicians, systems, and families. We should:

Lower barriers to staying on meds

Support youth with mental health needs

Also: Some youth will want to taper sooner, and that’s OK, but we should counsel on potential risks.

The takeaway is clear:
In today’s fentanyl-driven overdose crisis, short-term treatment with meds may not be enough.

Staying on buprenorphine longer = better protection from overdose.

Even when things are improving, staying on treatment may be the safest option.

In our study of 11,649 youth ages 13-26:

Only ~1 in 4 stayed on buprenorphine consistently for a year.

But those who did had nearly half the risk of overdose.

76% higher if stopping <3 mo

82% higher if stopping 3-9 mo

New study out today!
It answers a question I often hear from young people with opioid addiction & their families:

β€œHow long do I need to stay on medication?”

We know buprenorphine can be life-saving, but until now, we haven’t had strong data to guide that timeline…

Got to spend time with @massgovernor.bsky.social yesterday discussing policy changes to expand vaccine access across Massachusetts:

- Guaranteeing insurance coverage of vaccines
- Issuing a standing order for Covid shots
- Leading through the Northeast Public Health Collaborative

Yesterday’s news revived false claims about circumcision, Tylenol & autism.

Let’s be clear: There’s no strong evidence linking either to autism.

8 out of 10 Americans trust their doctor for health advice. Trust themβ€”not politiciansβ€”if you have questions.

We’re here to help. #MedSky

Breaking new data:

83% of Americans still trust their doctor -- even as faith in agencies like the CDC drops (now ~50%).

Trust in the AAP stays strong (69%). Most reject false Tylenol–autism claims, but politicization of public health remains a threat. #MedSky

The MMR vaccine is one of the most stunningly effective medical therapeutics in existence. It’s also safer than most of your everyday activities. This is simply an attempt to stop people from vaccinating.
