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.

    This is basically the fluoride ‘debate’.

    (Yes, fluoridating the water supply is good.)

      I specifically remember my bio mom ranting about how we all would have telekinetic powers if not for the fluoride in the water. She believed that was the ‘real’ reason the government did it.

      Also, if you are injesting enough flouride to cause health issues when you brush your teeth, you are brushing horrifically wrong.
