Using live viruses to combat serious diseases such as polio led to safety concerns; in fact, the first successfully demonstrated live-attenuated oral polio vaccine (1950) was never approved for . They are not as similar to a real infection as live, attenuated vaccines so often people need multiple doses of this kind of vaccine to maintain immunity. Among the various vaccine modalities, live attenuated vaccines have been considered the most effective, since they closely replicate a natural infection without the burden of the disease. For example, the measles virus used as a vaccine today was isolated from a child with measles disease in 1954. These vaccines elicit strong immune responses that can confer life-long immunity after only one or two doses. Live attenuated vaccines: avoid use in those who are clinically Live attenuated vaccines currently licensed in the United States include: 6, Adenovirus vaccine ( Adenovirus type 4 and type 7, for military use only) Chickenpox (varicella) vaccine ( Varivax) Cholera vaccine (Vaxchora) Influenza nasal spray vaccine ( FluMist) Measles, mumps, and rubella (MMR) vaccines (M-M-R II, Priorix) However, both vaccines demonstrated a potential to cause adverse effects, which have been associated .
