âThe Americans continues be one of the best shows on television,â Eric Schrier, President of Original Programming for FX Networks, said in a statement.
A attenuated vaccine is a vaccine created by reducing the virulence of a pathogen, but still keeping it viable (or live). Attenuation takes an infectious agent and alters it so that it becomes harmless or less virulent. These vaccines contrast to those produced by killing the virus (inactivated vaccine).xamples of live (example attenuated) vaccines include: 1  Viral: measles vaccine, mumps vaccine, rubella vaccine, Live attenuated influenza vaccine (the seasonal flu nasal spray and the 2009 H1N1 flu nasal spray), chicken pox vaccine, oral polio vaccine (Sabin), rotavirus vaccine, and yellow fever vaccine.
To produce an immune response, live attenuated vaccines. must replicate (grow) in the vaccinated person. A relatively. small dose of virus or bacteria is administered, which. replicates in the body and creates enough of the organism. to stimulate an immune response.lassification of Vaccines There are two basic types of vaccines: live attenuated and inactivated. The characteristics of live and inactivated vaccines are different, and these characteristics determine how the vaccine is used.
