Scientists say they would like to look at a broader population to see if the effects are the same in women.

While there is still a part of the population that worries about the damage vaccines might do, the majority of parents are having their children immunized, according to the latest Centers for Disease Control and Prevention Morbidity and Mortality Weekly Report.

The health center's study found that over 90 percent of parents are taking their babies in for shots to protect them against polio, hepatitis B, chickenpox and measles, mumps and rubella.

There is, of course, still room for improvement.

The CDC would love all children to get vaccinated. There has also been a drop in the number of parents who are getting their children follow-up boosters and vaccines in the second year of their child's life. That second round typically includes a shot that protects children from tetanus, whooping cough and diphtheria, called the DTaP vaccine.

Measles has made a comeback in the United States. There have also been several outbreaks of whooping cough in the last few years. Some studies have found the incidents of these outbreaks are higher in areas where people have not had their children vaccinated.

Vaccines are essential to protecting children from life-threatening diseases and to protect the rest of the population from disease outbreaks. The CDC estimates vaccines will prevent 322 million illnesses, 21 million hospitalizations and 732,000 deaths during the lifetime of those born between 1994 and 2013.

Your signature on a document is unique. So is your bacterial signature.

Yes, the little microscopic bits that are on your body are so present that scientists find they move with you.

A new study in the journal Science shows that every single room in your house is brimming with the bacteria that is unique to you and your family. Every single place you touch — a doorknob, a window, the knob on the stove — is covered with the stuff.

The research comes from scientists who are part of the Home Microbiome Project. They sequenced the bacteria from seven families and studied them over six weeks. Even when a family moved into a new house, scientists found their unique signature 24 hours later.

For people who worry about germs in hotel rooms, they may not need to any more. Scientists find that your bacteria essentially colonizes whatever room you are in.

People with multiple sclerosis who eat a diet high in salt may face more complications than those who don't, according to the latest edition of the Journal of Neurology, Neurosurgery Psychiatry.

The study observed 70 patients with MS over two years and found the patients who ate a lot of food with salt were 3.4 times more likely to develop a new lesion than those who consumed low-salt diets.

The results suggest those who are suffering from MS should find ways to lower the amount of sodium in their diet.
