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.

I think that's the basic premise of the Star Trek hypospray. Pressure pushing in medicine rather than a needle.

A lot slower, though. Article says it takes a minute and a half.

Also consider the people who have needle phobias. My heart starts to race before getting a vaccine. If I have to give a blood sample I will faint.

I’m getting woozy talking about this.

That's weird. My heartrate and blood pressure go down before getting a shot.

Then I go down, and feel like death for a day and like I'm in rehab for a week.

Funny thing, I'm not really getting woozy talking about it (a little, but more sympathetic memory of it).
