New research suggests that women who are more prone to most common vaginal infections like bacterial vaginosis can prevent the recurrence if they follow hormonal contraception.
You can use either birth control pills or Depo-Provera injections to prevent frequent vaginal infections.
Researchers conducted a study in 330 women with a mean age of nearly 25 who are diagnosed with sexually transmitted diseases at least twice from April 2005 to October 2006. 
Almost 40.3% of women were diagnosed with bacterial vaginosis. The women were prescribed a contraceptive, either progestin only (such as Depo-Provera) or estrogen-progestin combination (a birth control pill).
Women who were taking an oral contraceptive that included estrogen and progestin were 34 percent less likely to have a recurrence of bacterial vaginosis than women not taking a contraceptive.
