Yes! It's Friday. Hope everyone had a wonderful week. Here's your roundup of health news.

The big news in the health care reform front was the preisdent's shifting stance on the so-called public option. On Monday, it seemed Obama was ready to cave to critics and drop the idea of a public insurance option. Then, the White House backtracked, saying it wasn't shying away. We admit it; we're confused. Also confusing is what might replace the public option -- nonprofit co-ops. What are those, you ask? Folks here , here and here offer a few explanations.

In other health care news, the Brits are defending their system against U.S. attacks. Others ask if it's even fair to compare the American system with Canada's and countries in Europe.

Remember the craziness over "death panels" last week? Well put that silliness aside and read this very well-done piece about how doctors -- specifically palliative care specialists -- navigate end-of-life issues.

Stephanie wrote earlier this week about swine flu, er, H1N1 vaccine trials in kids, who are among the five priority groups who would get the shot. But maybe those priority groups are all wrong, says a new analysis by Yale and Clemson researchers. Instead of health care workers and pregnant women, the vaccine should be given first to children 5-19 and their parents to be most effective, the study says.

Cake that's good for you? Sign me up. The American Cancer Society asked the baking society to come up with a more nutrious birthday cake. Recipes included.

You know what's not good for you? Zombies. But how does one prepare for say, a zombie invasion and a subsequent assault on public health? I know, this has been keeping me up at night too. Well, someone actually did the math. The folks at the WSJ's health blog explain.

And with that, have a healthy and happy weekend!
