One reason for cautious optimism: the vaccine used for the swine flu in 1976 used an attenuated “live virus” for the vaccine instead of a inactivated or “killed” form, increasing the probability of adverse side effects among susceptible groups of people receiving the vaccination.
The vaccine Pfizer is developing is an RNA vaccine, which offers advantages over a live virus vaccine: RNA vaccines are faster and cheaper to produce than traditional vaccines, and a RNA based vaccine is also safer for the patient, as they are not produced using infectious elements. [
