WASHINGTON (Reuters) - Two studies published on Thursday confirmed that a single dose of swine flu vaccine can protect people from the new pandemic H1N1 virus -- welcome news to global health officials who had worried that people might need two doses.

Australian vaccine maker CSL Inc. released new data showing its vaccine got what would be considered a protective immune response with a singe dose, and Swiss drug maker Novartis presented a study confirming a report from last week showing its vaccine worked at an even lower dose when boosted with an immune system compound called an adjuvant.
