More great news: H5N1 vaccine less effective than hoped

CNN is reporting that the latest H5N1 “avian flu” vaccine is less effective than previously thought. The vaccine, now in clinical trials, is less than 50% effective. The vaccine for the more common influenza viruses are from 75 – 90% effective. Oh yeah, did I mention that the vaunted Tamiflu is not as effective against H5N1, as previously thought, either?
