FOX News – Researchers design nasal vaccine to protect against chlamydia
For the first time, researchers have designed what they say is an effective chlamydia vaccine that can be administered nasally. Preliminary findings from animal studies conducted at McMaster University in Canada suggest the test may show promise. According to the Centers for Disease Control and Prevention, chlamydia is the most commonly reported sexually transmitted disease (STD) in the United States. It can be cured with prompt antibiotic treatment, but untreated, chlamydia can lead to infertility, genital tract infections and pelvic inflammatory disease. Worldwide, the STD affects 113 million people.

The New York Times – I.V.F. Does Not Raise Breast Cancer Risk, Study Shows
Women undergoing in vitro fertilization have long worried that the procedure could raise their risk for breast cancer. After all, the treatment requires temporarily increasing levels of certain sex hormones to five or 10 times the normal. Two of those hormones, estrogen and progesterone, can affect the course of certain kinds of breast cancer. A series of studies over the past decade suggested that these former patients may have little to worry about. Experts remained cautious, however, because women who had undergone I.V.F. in the 1980s had not yet reached menopause by the time of the research.

The Huffington Post – Antibiotic-Resistant Gonorrhea Is A Looming Threat
The Centers for Disease Control and Prevention reported Thursday that Neisseria gonorrhoeae ― that is, the bacteria that causes gonorrhea ― could be developing resistance to our last-line antibiotics that treat it. The CDC’s current gold standard treatment for gonorrhea is a combination of two drugs, azithromycin and ceftriaxone, to ensure that if one drug doesn’t kill the bacteria, the other will finish the job. Now, a rise in antibiotic resistance among these two bacteria since 2014 has experts worried.
