When one thinks of vaccinations, one always imagines needles. However, up until a few decades ago another popular method of mass vaccination was jet injectors that required no needles.
As explained in the Denver Post, “A jet injector uses high pressure to force a vaccine or other medication through a person’s skin.” It was the speed of the jet injectors that allowed authorities to vaccinate a large number of people in a short period of time, hence they were most widely used in schools and during military enlistments in the USA.
Recently, a video of jet injectors being used for vaccinating people is going viral after it was shared on Twitter by a popular account Fifty Shades of Whey (@davenewworld_2) on Saturday.
The undated black and white clip was captioned, “The US military used compressed air to deliver vaccines through the skin without a needle from the 1960s until the 1990s”. The clip garnered over 2.8 lakh views.
Commenting on it, a Twitter user wrote, “I don’t remember it being more painful than a syringe and it’s far more efficient (both in terms of time and waste). You can’t flinch or move at all, though, or it’ll cut you (or give you a half-injected blister). It helped to kinda lean into it (which I did the second time).”
Another person recalled, “Fully remember these as a military dependent child and later when I served. Never had a scar from them but it was more traumatic than a needle”.
