2. Flu shot effective against drifted influenza, nasal spray vaccine less so
   12-13-2006 · EurekAlert!
   During a year in which the circulating strains of influenza showed genetic differences from the strains in vaccines, the traditional killed-virus flu shot was found to be effective in preventing influenza in healthy adults. The live attenuated-virus nasal spray vaccine also prevented illnesses, but was less effective.

3. Cell death suppression increases efficacy of M2 vaccines
   01-15-2008 · EurekAlert!
   Scientists from Cure Lab, Inc. in collaboration with Boston University School of Medicine published new findings indicating that unmodified M2 may have a negative effect on anti-influenza vaccination. The researchers also demonstrated how this detrimental effect of M2 can be eliminated, thereby allowing any future M2-containing vaccine to be both broadly protective as well as safe. This study appears in the Jan. 16 issue of the online journal PLoS ONE.

5. Cancer vaccines -- Taking a jab at cancer by stimulating the immune system
   04-17-2007 · EurekAlert!
   As the first FDA-approved cancer vaccine, designed to protect against human papillomavirus, has moved from scientific discussion to social debate, other vaccine studies are continuing to make progress. While HPV vaccine efforts had the "benefit" of a viral source for the disease, other researchers are developing vaccines for cancers that are not virally based, in an effort to coax the immune system into attacking cancerous cells.

8. Virus used to create experimental HIV vaccines directly impairs the immune response
   11-15-2007 · EurekAlert!
   Leading efforts to create an HIV vaccine have hinged on the use of viruses as carriers for selected elements of the HIV virus. Recently, however, evidence has emerged that some of these so-called viral vector systems may undermine the immune system and should not be used for vaccine development. Now, a new study from scientists at the Wistar Institute provides strong support for the idea that some viral-vector vaccines may cause more harm than good.
