Ultrasound can push vaccines into the body without needles (www.newscientist.com)

Vaccines can be delivered through the skin using ultrasound. This method doesn’t damage the skin and eliminates the need for painful needles. To create a needle-free vaccine, Darcy Dunn-Lawless at the University of Oxford and his colleagues mixed vaccine molecules with tiny, cup-shaped proteins. They then applied liquid mixture to the skin of mice and exposed it to ultrasound – like that used for sonograms – for about a minute and a half.

One of my friend's friends has a PhD in psychology, but she thinks that nuclear radiation has healing properties and told me to move out of NYC because there was too much 5G everywhere. She still uses a smartphone though, just on a selfie stick on speakerphone 🤣 She also told me that she was afraid of the radio in her car because of the radio waves.

She could at least use wired headphones. Or is it one simple trick to stop people from calling you?

She's just a bit out there, there is no logic in her actions.

In a way she’s actually not wrong. That’s what radiotherapy is. Focused nuclear radiation to heal cancer.
