Vaccine efficacy and duration of protection

Will vaccines be able to eliminate or eradicate COVID-19?

  • The first priority is to save lives and control the epidemic. To consider the possibility of eliminating or eradicating COVID-19, we would need to see how long the vaccines provide coverage for, and how effective vaccine programmes are in achieving high coverage.
  • But even the existence of a highly effective vaccine is no guarantee that we will be able to eliminate or eradicate the virus. The likely scenario in the context of an effective global vaccination programme is that the virus would become an endemic virus with a low level of threat.
