Neff states that the small pox vaccine confers immunity for only 3 to 4 years. Millions worldwide, and about 90% of individuals in the U.S. over the age of 35 (like me and half the country's population) that were vaccinated before the end of the mass small pox vaccination campaign, are no longer immune to smallpox. Reduced immunity --- sure --- no immunity whatsoever, I'm not so sure about this! Are you? Using ONLY most recent scholarly evidence (not newspaper or magazine articles) to the contrary and summarize your findings in one succinct paragraph. Be sure to cite a scholarly article---print version---(not Internet stuff) at the end of your summation in APA format and style. Please be careful with your citation!
