  • New viral strains arise through a process called antigenic shift, or reassortment, when at least two viruses combine.

  • These errors, which result in what is called antigenic drift, explain why the flu virus is different each season and why new vaccines are needed each year.

  • These changes, known as antigenic shifts, can sometimes result in very deadly strains.

  • These small changes in the virus are called antigenic drift, and over time changes in the virus can accumulate to the point that last year's vaccine is no longer effective.
