Do you think these mutations represent antigenic drift or antigenic shift? Explain, including in your answer a definition of both antigenic drift and antigenic shift. 2. Which of these two strains (Delta or Omicron) would you predict would be more likely to demonstrate "immune escape" from the originally developed (2020-2021) vaccines, i.e., the vaccines would be less protective against? Why is this? Please number your answers 1 and 2 and explain briefly but thoroughly.
