“On Wednesday, the Food and Drug Administration approved lenacapavir for the prevention of HIV. Clinical trial data from last year suggest just two injections a year provide near-complete protection against an HIV infection…
The twice-yearly injection offers a more convenient alternative to the current standard of care for HIV prevention, a daily pill called Truvada. This pre-exposure prophylaxis (PrEP) is 99% effective at preventing HIV infection in clinical trials, but some people face significant barriers in taking a daily pill. One study found oral PrEP’s was only 26% effective in certain groups, in part because of skipped doses.”

Tuberculosis Is Now Rare in Rich Countries — Here’s How It Happened
“By the middle of the 18th century, around 1% of London’s population was dying from tuberculosis (TB) every year. You can see this in the chart below, which shows modeled estimates of TB death rates in London.
Let’s pause on that. Every year, 1 in 100 people died from TB. That means that if you lived in London, every five years, 1 in 20 people you knew might have died from it. That’s one person for every three or four households.
If London were to experience that scale of infection and death today, tuberculosis would kill around 90,000 people every year. That’s almost double the number who currently die in London from all causes — cancer, heart disease, the flu, COVID-19, dementia, road injuries, homicides, and many others.”

Botswana Leads the Way in Eliminating Mother-to-Child HIV
“Botswana has been validated as the first high HIV-burden country in the world, and the first in Africa, to reach the World Health Organization’s Gold Tier status for eliminating vertical transmission of HIV as a public health issue…
According to the 2024 UNAIDS Spectrum estimates, Botswana has approximately 360,000 people living with HIV, with 98% of pregnant women living with HIV receiving treatment. As a result, the rate of mother-to-child transmission has dropped to just 1.2%, well below the 5% benchmark, and fewer than 100 infants were born with HIV in 2023.”
