I don't know who needs to hear this but I'm seeing long haul COVID in kids and it is.. frightening. 1. Chronic headaches 2. Dysautonomia 3. Menstrual irregularities 4. Chronic cough and respiratory problems 5. Depression and anxiety All triggered after seemingly mild covid inf.

From 7/21-1/22, 133 kids were hospitalized Children's Hospital with a primary dx of acute COVID; 65 were <5 yo and 22 required ICU care. Two died. Another 37 were hospitalized with MIS-C, 14 in ICU. No other vaccine-preventable disease causes this much misery. Vaccinate every eligible child!

Mystery illness has killed over 1500 kids under 18 the past two years. 500 of those under 5. 7500 with a severe inflammatory condition after this infection. Countless others with long term symptoms. Would you consider this “mild”. As a pediatrician I would NOT! #ImmunizeUnder5s

Ok. It’s Monday April 4. U.S. FDA Mandy K. Cohen, MD, MPH CDC when can my 4yos get vaccinated.

Hey Moderna U.S. FDA CDC what’s the hold up? Parents are anxiously waiting for a #covidvaccine for #kids under 5. #UrgencyOfEquity #CovidIsNotOver

Parents of kids <5 feel abandoned. As adults clamor for boosters and cry for a “return to normalcy,” the FDA still hasn’t approved an <5 vaccine. We deserve clear and timely updates after many delays and poor communication. Dr. Robert M. Califf Mandy K. Cohen, MD, MPH ImmunizeUnder5s

I saw children die of AIDS because medicines that saved their parents’ lives were not approved for them, so the seeming lack of urgency around COVID vaccines and therapeutics for young children is triggering. This wasn’t supposed to happen again almost 30 years later.

Now that Moderna has submitted all pediatric data to U.S. FDA, we urge an immediate, transparent and thorough review. Families of children under 5 have waited a long time for the reassurance of a safe and effective vaccine.

Full Moderna data submitted U.S. FDA FDA Biologics. Parents of u5’s are watching you and waiting. Review now. Review now. Review now. ImmunizeUnder5s

Dr. Rebecca Karp Leaf, MD (MGH Hematology) and Dr. Lauren Stern (BMC Nephrology) show their support and attend the #PlannedParenthood Bans Off Our Bodies March at Boston Commons.

The idea that COVID is harmless for otherwise healthy children is absurdly and demonstrably false. And the corollary argument that kids <5, therefore, don’t need vaccine is not only false, but immoral; 486 already have died. Parental choice cuts both ways. Authorize the vaccine!

If parents can opt-out of having their kids vaccinated against COVID, others should have the right to opt-in on a <5 vaccine we have every reason to believe will be safe and effective in reducing severe acute disease, late effects and death. Risks and benefits cut both ways.

How can you go from sequence of a novel virus to 2 vaccines with 95% efficacy and safety (>75,000 participants in RCT trials) in 10 months and not, in 2.5 years, go after pan-β-coronavirus and nasal vaccines with the same aggressive (OWS) template?

Congratulations to my amazing husband, David Leaf, on his promotion to Associate Professor of Medicine Harvard Medical School!!!

Ceci died unexpectedly on Dec 5, 2022 at 14 months old. She was our daughter & we are devastated. She was so smart, smiley, stubborn & squishy. She adored the rabbits in our yard & playing with her nanny “Shang NaiNai” & sisters. She is loved & missed beyond comprehension (1/5).

I’m so fortunate to work with and learn from the extraordinary Steph Kiser and to have her as an integral part of our #SCD team. Join us on Friday as we explore the role of palliative care in #sicklecelldisease

My 3 year old daughter Lila was recently diagnosed with a VERY rare and aggressive type of #leukemia. 👉 It’s potentially treatment resistant… AND 👉 Requires a bone marrow transplant. A🧵with all the details we have so far 👇 Please @Twitter help me save my little girl.
