No needle vaccines, 1967

people who got these in the 60's still have the scars.

Many people born pre 1970s have scars from these on their arms.

All your grandparents and parents that got these back then have the same scar on their arms 😆

These were called jet injectors. They administered the vaccine through a high-pressure narrow jet of the vaccine liquid, penetrating the skin to deliver the vaccine without a needle. They were especially useful in scenarios where rapid, large-scale immunization was necessary. The use of jet injectors largely declined due to concerns about the potential for cross-contamination between patients and the challenges in maintaining the sterility of the device. There were fears that blood-borne pathogens could be transmitted if the injector was not properly cleaned between uses.

They used high-pressure stream jet to puncture the skin surface without using a needle. But needles are usually painless if you ask me, don’t know why some people are scared at the sight of it
