After US Cuts AIDS Aid, Treatment Volume Plummets 30% in Uganda and Zimbabwe

Real data from four organizations in Uganda and Zimbabwe: treatment coverage fell 31.5%, testing fell 63.8%, PrEP use fell 71.6%—cutting aid means the virus keeps spreading and more people die from preventable AIDS.

This episode is data-dense, covering everything from hard numbers on cut funding to AI-designed heat-stable vaccines, but the Uganda/Zimbabwe evidence chain is most solid and worth noting separately.

US Aid Cuts Cause AIDS Treatment Coverage to Drop One Third

A Lancet Global Health study tracked four NGOs in Uganda and Zimbabwe receiving PEPFAR funding that serve high-risk populations. After US funding stopped, antiretroviral treatment recipients dropped 31.5%, prevention services like condom distribution fell 62.7%, HIV testing fell 63.8%, and PrEP use fell 71.6% at three reporting organizations. Griffin argues that untreated people continue spreading the virus, newly infected people can't be detected or treated, this snowballs while the decision has no justification.

Whether Vaccines Cause Fever May Depend on Your Gut Bacteria

A Science study tracked 171 healthy young people receiving mRNA COVID vaccines. Those prone to fever had chronic mild intestinal inflammation before and after vaccination, with higher flagellin protein expression in their microbiota. Transferring these people's microbiota into germ-free mice produced stronger inflammatory responses to vaccines, pointing to innate immune recognition of bacterial flagellin. Diet can change flagellin production. The episode notes vegetarians run fewer fevers but develop antibodies just as well—no fever doesn't mean the vaccine failed, just that diet may modulate this particular inflammatory response.

Raw Milk Has No Extra Health Benefits, Only Infection Risk

The American Academy of Pediatrics released a new policy statement. Raw milk and raw dairy products remain legal in at least 27 US states but carry ongoing risk of infection from Listeria, Campylobacter jejuni, Salmonella, Brucella, E. coli O157, and other pathogens—especially dangerous to pregnant women, fetuses, infants, elderly, and immunocompromised people. The statement explicitly says claimed health benefits of raw milk have no evidence; pasteurized dairy provides equivalent benefits without extra infection risk. Griffin argues banning is impractical; instead, removing the profit incentive from sales chains makes sense, letting committed drinkers bear their own risk through dairy co-ops they own.

The Widely Shared Shingles Chart May Be Misread

Epic Research analysis claims the first chickenpox-vaccinated cohort shows dramatically lower shingles rates in adulthood. But Griffin and Vincent spot a design flaw on air: it plots incidence by birth year rather than age at disease, so 1968-born people correspond to their 50s data (2019-2026), yet the vaccine didn't arrive until 1995. Shingles rates were already dropping in late-1960s birth cohorts. Their conclusion: this widely circulated chart showing ‘vaccine works’ may be misread. What actually matters is that vaccinated 20-year-olds still show 6.9 per 10,000 shingles cases—lower than it should be.

AI Designs mRNA Vaccines Stable at Room Temperature for Two Months

A Nature Biotechnology study used an AI system called AGENT, combining high-throughput experiments and Bayesian optimization. In six iterations over a month, it found solid-state stable formulations for mRNA lipid nanoparticle vaccines matching Moderna and Pfizer-BioNTech configurations. At 37°C (body temperature), they retained 100% bioactivity after 2+ months storage and triggered immune responses in rodents and non-human primates equal to fresh-made vaccines. This means future mRNA vaccines may not need ultra-cold chains and could even be applied as patches on skin. But Griffin and Vincent note this is only animal data; whether the vaccine remains stable after rehydration still needs clinical trials.

Congo's Ebola Outbreak Approaches West Africa's Record but Still Climbing

Congo's Ebola epidemic has reached 9166 confirmed cases and 4413 confirmed deaths, approaching West Africa's historical peak (~11,000 cases). Over 140 days into the outbreak, most new cases still occur in transmission chains contact tracers cannot reach. One-third to two-thirds of deaths happen at home and in communities, not treatment centers. Kenya reported its first imported case last week—a man who returned from Congo via Uganda died of it. CDC case curves show continued rise with no sign of plateau.

Lifelong Measles Immunity Is Proven by a 1846 Island Outbreak

A listener asks why a 77-year-old should consider a booster in a measles hotspot—does measles immunity really last a lifetime? Griffin and Vincent cite real historical evidence: an 1846 Faroe Islands measles outbreak investigated by Danish physician Peter Panum. Everyone who survived the outbreak 65 years prior (1781) was immune; everyone who never had measles was susceptible regardless of age. This classic observation remains the main evidence for ‘measles infection confers lifelong immunity’, not theory but 180 years of empirical data.

The whole problem with the world is that fools and fanatics are always sure of themselves, while wise people are full of doubts.

So, basically, it doesn't matter whether you have a fever or not, but if you don't want a nasty fever , you're going to have to make some lifestyle changes, right?

Daniel Griffin9:06

These alleged benefits have no evidence base and do not outweigh the risks of consuming unpasteurized milk.

When people believe a fairy tale, and it's a fairy tale that contradicts easily verifiable evidence, it shows that people underestimate the role of evidence in shaping their internal belief system.

Yes, and it does not stabilize. That's the thing. This is what I was looking for. It continues to grow.

Daniel Griffin30:12

He found that everyone who had survived the previous outbreak in 1781, 65 years or more ago, was fully immunized against measles during the 1846 outbreak .
