From NPR.org: A vaccine trial is called 'unethical' and a 'unique' opportunity. Is it on or off?

https://www.npr.org/2026/01/22/g-s1-106571/vaccine-trial-hepatitis-b-guinea-bissau

"A controversial study on hepatitis B vaccination in Guinea-Bissau that was funded in part by the U.S. CDC has been halted.

Yap Boum, PhD, MPH, a senior official at the Africa CDC, said the study was 'cancelled' during a press briefing on Thursday morning.

He noted, however, that conversations between officials in Guinea-Bissau and the U.S. are ongoing, since research on hepatitis B in that country is needed."

Pregnancy – MTCT Prevention

▪ Start TDF (preferred) or TAF when HBV DNA >200,000 IU/mL
▪ Begin at week 28 (consider week 16 if HBIG unavailable)
▪ Stop at delivery if no other indication; monitor closely

2025 guidelines standardize timing, incorporate TAF, clarify earlier start options, and define stop/monitoring strategy—supporting globally applicable MTCT prevention.
