Since squalene in the H1N1 vaccine is a hot topic in alternative health circles as a reason not to get the shot, I thought I would mention that the four vaccines that were just cleared by the FDA for use in the US do NOT contain squalene as far as I have been able to determine from press releases. GSK's vaccine should be approved shortly. So regardless of what you think about squalene, it's not an issue here in the US.

Novartis and GSK do have versions of the H1N1 vaccine with squalene, but those are not the versions that were just approved. Other countries may use the versions containing it, but since early clinical trials show unexpectedly good immune response to just a single dose of the non-squalene version, it's possible that those countries may switch to a non-squalene version, too.
