College Microbiology
Which is more dangerous to human beings-antigenic DRIFT or antigenic SHIFT-and why?
  1. Antigenic DRIFT-since this produces the quickest and largest degree of changes in the virus structure and we may not have immunity against it.
  2. Antigenic SHIFT-since this produces the quickest and largest degree of changes in the virus structure and we may not have immunity against it.
  3. Antigenic DRIFT-the small changes make the virus look like something we already have an immune response in place for, but we actually don't. This lets the virus hide from the immune responses needed to clear it out for a longer period of time.
  4. Antigenic SHIFT-the process completely changes the virus 100%, allowing it to jump into different species (i.e., from birds into humans). As such, we have no responses in place for the new virus.
