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.
Approved vaccines -- including the 2009 H1N1 swine flu vaccine -- are calculated to be much, much less risky than the diseases they prevent. For example, out of every million people who get a flu shot, one or two will get a serious neurological reaction called Guillain-Barre syndrome (GBS).nd since a large proportion of the population will get swine flu, the vaccine risk is far smaller than the disease risk. In clinical trials, 10,000 to 15,000 children and adults have received various manufacturers' brands of H1N1 swine flu vaccine.
