ACOG reaffirms that acetaminophen is safe for managing pain and fever during pregnancy. No reputable studies support suggestions like those in HHS’s recent announcement linking acetaminophen use in pregnancy to autism; in fact, high-quality studies show no such risk. https://bit.ly/47Wxc59

Vaccines save lives, but misinformation spreads faster than viruses. In some communities, it only takes one rumour to keep parents away from health centres.

Muslim faith leaders in Burundi are stepping in to stop that cycle. Here’s how. 🧵

More than 98% of families in this country choose to vaccinate their young children. But now, vaccine policy is being shaped by the small, extreme minority that doesn’t. This decision doesn’t reflect, protect or support families.

Since the 1970s, immunization has saved more than 150 million lives, from diseases like measles, diphtheria, pertussis, and polio. 

That's more than 4 million lives per year.

In 1974, high rates of vaccine-preventable disease prompted the WHO to launch EPI, the Expanded Programme on Immunization.

Half a century later, at least 154 million lives have been saved.

Proposed cuts to foreign aid could result in millions of HIV deaths and soaring rates of global HIV infections, new modelling study in The Lancet HIV estimates.

Explore the data 👉 tinyurl.com/5hud9dxm #MedSky
Figure showing projected effect of HIV programme funding cuts in 26 countries from 2000 to 2050, on HIV-related deaths. Anticipated 24% cuts capture the range of effects given by the proportional cuts and reallocated prevention budget to treatment scenarios (scenarios 2 and 3), while PEPFAR discontinued captures the range of effects with and without mitigation (scenarios 4 and 5). The dashed black lines show a continuation of historical 8·3% year-on-year reductions in new HIV infections and 10·3% year-on-year reductions in HIV-related deaths from 2024 levels.
