Giving flu vaccines to children can help protect the wider community, a new study shows.

The findings, published this week in the Journal of the American Medical Association, support the concept of "herd immunity," in which vaccinated members of a community provide a barrier against a disease for those who are unvaccinated.

Researchers, including the study's lead author, Dr. Mark Loeb, of McMaster University in Hamilton, Ontario, say the trial was conducted in 46 Hutterite colonies of a self-confined religious community in Canada. The Hutterites are an Anabaptist group similar to the Amish who live mostly in rural areas in western Canada and have little contact with non-Hutterite people around them.

During the 2008-09 flu season, researchers administered vaccines to 947 children between the ages of 3 and 15. Of those, 502 children in 22 colonies got the seasonal flu vaccine and the 445 children in the other 24 colonies were given the hepatitis A vaccine, the study says. There were more than 2,000 unvaccinated people in the combined communities.

Here is a look at what's new this week in family entertainment as adapted from reviews and ratings by Common Sense Media. Click on the links to read the reviews in full.

In Theaters Now: Remember Me
"Twilight" hunk Robert Pattinson stars in "Remember Me," a coming-of-age drama featuring two young adults with major issues. The film is dark and serious and features more violence, strong language and sexual content than you might expect in a movie presumably aimed at teens. Rated PG-13, Iffy for Kids 14-15

DVD: Planet 51
An animated film set in an alien version of 1950s America, "Planet 51" is a children's movie that tries hard to entertain parents, as well. While the suggestive humor and cultural references likely will go over their heads, kids will still find something to laugh about as alien kids try to send a wayward Earthling back where he belongs. Rated PG, OK for Kids 7+

TV: Pink Panther and Pals
Conflict and cartoon violence are the hallmarks of "Pink Panther and Pals," an animated series on Cartoon Network. This modern Pink Panther is a teenager, but he's just as silent and sneaky as ever as he battles his arch-nemesis, Big Nose. Despite the modern makeover, the show is as silly and fun as the 1960s original. Rated TV-Y7, OK for Kids 5+

In Mississippi, the Itawamba County school board told 18-year-old Constance McMillen that she was not allowed to bring her girlfriend to the prom, nor could she wear a tuxedo, only a dress. In doing so, they violated her First-Amendment rights.

This is basic discrimination. There was a time in our nation's history when black people were not allowed to dance in public with whites. Most Americans now see how wrong that was. This case is no different.

Just like when a teacher in New Orleans told a student last month that he was not allowed to wear an Indianapolis Colts jersey to school, Constance McMillen is being told that she may only express herself in a way that is approved by others.

That is the opposite of free speech.

"And this is our son Hubert. We won him in a raffle."

It could happen.

They're giving away some wild door prizes this weekend -- including in vitro fertilization treatments, two years of storage for frozen embryos and discounts on adoption services -- at the annual family-building conference of the Minnesota chapter of RESOLVE, a national infertility advocacy group.

The Minneapolis Star Tribune reports sessions will focus on medical and emotional issues associated with infertility and adoption. Topics include new medical treatments, legal issues and parenting options.

Whether it's getting them to master toilet training, trigonometry or taking out the trash, motivating kids sometimes involves a reward.

But are parents doing more harm than good by dangling a carrot -- or cupcake -- before their children? Although many psychologists say yes, a multitude of programs are trying new ways to motivate kids to learn, with some offering pizza, iPods and cold hard cash to encourage students to do better in school, increase time spent reading or get better grades.

Admitting there are few benefits to the carrot-and-stick approach, Daniel Pink, in the book "Drive: The Surprising Truth About What Motivates Us," examines what truly motivates people.

And while it may seem harmless to offer something in return for a child's hard work (an extrinsic reward), psychologists -- and Pink -- promote decades of research that points to long-term success through motivation that derives from within (intrinsic).

The National Institutes of Health convened an independent panel this week to re-evaluate so-called bans on VBACs, or vaginal births after cesareans. Many women who have had cesareans currently are not offered the VBAC option, even if they are at low-risk for complications.

"Declining VBAC rates and increasing cesarean delivery rates over the last 15 years would seem to indicate that planned repeat cesarean delivery is preferable to a trial of labor. But the currently available evidence suggests a very different picture: a trial of labor is worth considering and may be preferable for many women," says Dr. F. Gary Cunningham, chair of the 15-member panel, in an NIH press release.

The panel also advocates revisiting current VBAC guidelines, addressing malpractice concerns and conducting additional research on the factors that influence how a woman with a previous cesarean will deliver.

Are your boobs cold? Do you have a computer? Good news! Now you can keep your ta-ta's toasty with USB breast warmers for the low price of $49.95. That's right, just plug these rack roasters in, slip them under your bra, and -- bam! Happy hooters.

We're not sure where we'd ever use these (though the folks at AudioCube think they'd be ideal for checking out your friends' Facebook pages at the park in the winter). Would breastfeeding moms want to heat up the girls?

Would you use USB breast warmers?
