Handwashing helps the immune system by reducing the number of pathogens (like bacteria and viruses) you come into contact with, which can enter your body through touching your face, mouth, or eyes. By removing these germs from your hands, you lower the risk of infections, allowing your immune system to focus on other threats rather than fighting off preventable illnesses. It doesn’t directly boost immunity but supports it by decreasing the pathogen load your body has to handle.

Daniel - Cleveland clinic did a study of their employees:

“Major Cleveland Clinic study finds −26.9% effectiveness for influenza vaccine during the 2024–2025 respiratory viral season.”

Nic Hulscher posted a stack about it.

I sent this to a friend who is employed by the clinic so she has ammo this fall when they mandate the flu shot for all their employees. I’m pretty certain they didn’t share these results with their 50k+ employees. 😡

That is huge in my opinion and further supports that these vaccines need to be reevaluated. The −26.9% VE suggests that the antibodies induced by the 2024–2025 influenza vaccine were largely ineffective at preventing infection in this specific population, likely due to potential immune interference or the antibodies generated by the vaccine did not effectively neutralize the circulating influenza strains or pathogenic priming. That’s an issue that needs to be factored into risk vs benefit.
