A doctor administers a shot to a young girl. A new tuberculosis vaccine failed in its efficacy trial, with only a 17 percent effectiveness rate. It was the first trial of a TB vaccine since 1921.

The latest effort in the fight against tuberculosis has failed, reports the BBC. A new vaccine, known as MVA85A, underwent a major trial and was found to have an effectiveness rate of 17 percent – which is so low that it's not statistically significant. It was the first efficacy trial of a TB vaccine since 1921.

On Friday, the Obama Administration proposed rules that would allow religious organizations to hand off the responsibility of providing birth control to their employees under the Affordable Care Act. HealthDay says the proposed rules demonstrate how such organizations – like Catholic hospitals or universities – could offer their workers separate contraceptive coverage through a third party. Under the new rules, neither the people being insured nor the religious organization would carry the cost.

Not all dairy products are equal when it comes to bone health, suggests new research appearing in the Archives of Osteoporosis. It found that drinking milk and eating yogurt was linked to higher bone density in the hip, but not in the spine; cream, on the other hand, was linked to lower bone density overall.

Teen pregnancy has plummeted in New York City, and city health officials are citing two reasons: more contraceptives and teenagers' decision to delay sexual activity. The New York Daily News reports that in 2010, about 73 teen girls for every 1,000 got pregnant – down from nearly 99 in 2001.

And finally: HealthDay has news on a British survey looking at gay and bisexual teenagers, and whether it actually does "get better." While 56 percent of girls and 52 percent of boys, all aged 13 and 14, said they'd been bullied because of their sexuality, researchers noted that it seemed to get better with time. Still, gay or bisexual men were four times more likely to report bullying than their heterosexual counterparts – even at ages 19 and 20.
