Measles may seem like an ailment from a bygone era, but new evidence suggests that many US children may still be at risk today.

A group of US pediatricians has called for parents to get their children vaccinated for measles in response to an outbreak that began in Disneyland in California last December.

Since 2012, the Centers for Disease Control and Prevention (CDC) has suggested that all pregnant women receive the Tdap vaccine, even if they were vaccinated earlier in life. And new research found that Tdap was safe for both mom and baby.

One of the only vaccines that is known to prevent some forms of cancer is the HPV vaccine. Those who might worry about its safety have no reason to fear.

Health officials celebrated when a safe and effective vaccine to protect against HPV (human papillomavirus) was made available to the public.  But a vaccine can't protect the public if it isn't being used.

One of the conditions known to be a risk following some flu vaccinations is the autoimmune disease Guillain-Barre syndrome.

The two forms of the rotavirus vaccine currently administered to children do not cause the same gastrointestinal problems as the previous version of the vaccine.
