The article says that the risk of transmitting HIV doubles with the use of injectable contraceptives in a study of discordant sexual partners (ie one infected, one not).  Apparently at least two other studies have shown the same.

However there is a disturbing implication for breastfeeding, is there not?  Perhaps mothers given this contraceptive will infect their babies more readily, due to changes in the mother’s physiology or in the virus. Is anyone able to access the original study from The Lancet Infectious Diseases of Monday 3 Oct?  Any mention at all about breastfeeding?

Quoting from the report:  ‘The progestin in injectable contraceptives appears to have a physiological effect, scientists said. ....‘It could be that progestin causes “immunologic changes in the vagina and cervix” or could increase the H.I.V.’s “ability to replicate.”
