On a good year the vaccine is about 60 percent effective and on a bad one it prevents only 10 to 20 percent of flu cases. We receive lifetime vaccinations for smallpox chicken pox and meningitis but every single season theres a need for a new flu shot. All the evidence both from natural infections and from vaccine trials suggest that most people are making neutralizing antibodies the variety which prevents viruses from entering our cells.
