Remember when we almost had a black women president who led with peace, poise, power, promise, equity and justice?
Overwhelming to think of where we are and where we could be.. there will be a right & wrong side of history and I know where I stand.
We fight on. #Vaccines #PublicHealth

Vaccine counseling is key. Just this week we had several patients decline because of misinformation.
Whooping cough (pertussis) cases have skyrocketed by more than 1,500% nationwide since 2021.
Deaths tied to the disease are also up — hitting 10 last year, compared with about two to four in previous years — and cases are on track to exceed that total in 2025.

🔔 Just had a baby? Let’s talk about your MMR status.
If you weren’t fully vaccinated or immune to measles before pregnancy, postpartum is a great time to get caught up. Measles is highly contagious and dangerous for infants.

Measles is back—and newborns are too young to be vaccinated. As an MFM, I’m here to remind you: Protecting your baby doesn’t stop at birth.
