what-even-is-thiss:

My dad was telling me about something that he described as a “gun that put vaccines through my skin” when he was a kid and I looked it up and I think he’s talking about jet injectors

These things aren’t widely used anymore because if they’re not used correctly they can give some people infections but they used to be used in mass vaccinations.

Basically these things use pressure to get medication through your skin and into your fat and muscle layers underneath which… ouch but they work.

My dad says a couple of times during elementary school some med students and nurses showed up and they were all lined up on the playground and told to show their shoulders and the med students and nurses just locked and loaded these bad boys and pop pop pop pop pop a couple minutes later all the kids were vaccinated against whooping cough and they all went back to class with sore arms.

I don’t know why it’s funny to me. Probably because with the way my dad describes it he was clearly in that place when you’re a kid between like four and nine years old where something weird happens to you and you just move on from it. He was like seven and got hit with a vaccine gun with almost no explanation from the adults around him and went “okay well that was weird. Anyways, back to class.” Like wow. The weird shenanigans that you don’t think about till you’re well into adulthood. Like my dad is almost 60 and he’s just now remembering this now that all the covid vaccinations are going on.

Oh my god

fun fact the science behind these guns is why you should be very careful when working with hydraulics. if youre working with anything hydraulic and feel something that feels like a bee sting, immediately go to the hospital because it can get infected easily. the leak would look like just a single drop of water coming out but if you touch it, all the force will force the fluid into your body like the vaccine gun does.
