I got a mandatory flu shot while in Navy training using an [injector gun](https://en.wikipedia.org/wiki/Jet_injector). IIRC, the gun used high-pressure compressed air to inject the vaccine directly though the skin. Then I heard a rumor (urban legend?) about some guy who flinched when he was injected, and it cut his arm open. So after that I always requested a vaccine with a needle instead (and my request was honored because by then I was in the fleet and no longer in training). A few years later, they learned there could be cross-contamination and the spread of bloodborne diseases (like HIV) by means of [splash-back](https://en.wikipedia.org/wiki/Jet_injector#Splash-back), so the Navy stopped using the injector guns entirely some time before I left active-duty in 2002. --- _[View the full topic](https://boards.straightdope.com/t/coronavirus-covid-19-2019-ncov-thread-2020-breaking-news/847758)._
