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.
No, a flu shot cannot cause flu illness. Flu vaccines given with a needle are currently made in two ways: the vaccine is made either with a) flu vaccine viruses that have been âinactivatedâ and are therefore not infectious, or b) with no flu vaccine viruses at all (which is the case for recombinant influenza vaccine).
