I sometimes need injections in the developing world. I carry my own syringes in a couple of sizes; this has never been questioned during even very thorough searches. When possible, I buy fresh syringes in original American or European packaging at local pharmacies for immediate use; the ones I'm carrying are for emergency use. I buy fresh medications, including injectable antibiotics or vaccines, the same way.

There are always people who'll swear up and down that standards of care in their region, country, or favorite clinic are beyond reproach. I've seen and heard enough exceptions so that I try to exercise caution whenever I can. This aside, it's also the case that the situation described probably doesn't apply to the sorts of clinics and hospitals at which you or I would find ourselves if needing an injection in Delhi. For the most part, medical personnel in even very remote areas do know how to provide sterile equipment and administer injections properly. It is the desperately poor of the world who generally get the shaft; we westerners are very, very fortunate to be able to pay for a better standard of care.

Although you'll note: official denials of the transmission of mad cow disease due to livestock feeding practices, mass transmission of HIV to hemophiliacs, etc. etc. etc. in our own countries.
