Scary but also a fascinating bit of 🧪.
If you know someone considering to NOT get their child vaccinated for #measles, remember that measles virus (but not the vaccine) *erases* the existing immunoligical memory. This "immune amnesia" puts someone at GREAT risk for other diseases after.

Measles and Immune Amnesia | ASM.org
Measles is much more serious than a rash and fever: it also causes immune amnesia and leaves patients especially vulnerable to secondary infection.

Also worth noting is that the new US 2035 NDC emissions target includes methane reductions of at least 35% by 2035. As the fact sheet notes: "Cutting methane emissions is among the fastest ways to reduce near-term warming and is an essential complement to CO2 mitigation."

The field of "ultra-processed" food research & its media coverage are littered with poor definitions & comparisons, w misleading conclusions. This creates an illusion that UPFs provide new insights, but it's all slight-of-hand. @mbolotnikova.bsky.social takes a deep dive www.vox.com/future-perfe...

Real-world effectiveness and causal mediation study of BNT162b2 on long COVID risks in children and adolescents
Our study suggests that BNT162b2 was effective in reducing risk of long COVID outcomes in children and adolescents during the Delta and Omicron periods. The mediation analysis indicates the vaccine’s effectiveness is primarily derived from its role in reducing the risk of SARS-CoV-2 infection.
