In My Honest Opinion -- (I, MHo)

OpenIdea: Studying mosquitoes to inject vaccines

Think of the children… who wouldn’t be crying when they need to get vaccinations.  Mosquitoes can suck out a bit of blood without you really noticing too much, so a needle with similar characteristics as a mosquito sucker should able to inject medicines into people, right?  Perhaps this has already been tried, and injecting enough material via a microscopic needle would just take too long or something..?  Where are the Star Trek medicine injectors? (I think they were called Hyposprays…)
