Skepticism is growing over the H1N1 vaccine, this time from some doctors.
The government continues to say the vaccine is safe.
The FDA sent out a letter, reminding doctors explain the vaccine is made just like the seasonal flu one, and they tested thousands of patients with no significant side effects.
World Health Organization officials say they'll ship another 50 million doses of the vaccine over the next few weeks.
And the trick to keep your kids from getting H1N1 could be just a few germs away.
A study published in the magazine "Pediatrics" found healthy children between three and five years old, who were fed pro-biotics, had fewer cases of the cold and flu.
Pro-biotics are good germs that help optimize immune systems.
They're found in several fermented foods, including miso soup, soft cheeses and yogurts.
Doctors say pro-biotics isn't a cure, but it will boost your immune system until a vaccine is available.
