A new study finds no increased risk of getting a blood clot after getting vaccinated for HPV. There had been some research suggesting a link. But researchers in Denmark looked at more than half a million women who received the vaccine. They found no increased risk of blood clot in the 42 days after vaccination - which is the main risk period.
And a new study finds the smoking cessation drug Varenicline - known by its brand name Chantix - is more effective when combined with nicotine replacement therapy. Researchers in South Africa divided nearly 500 smokers into two groups. They found nearly half the people who received the combination were smoke-free six months later, compared to 33 percent who received just the drug.
