Three regulatory approved Covid-19 vaccines with high efficacy results have already been rolled out in several countries, while researchers are currently testing 64 vaccines in clinical trials on humans.

They reached the conclusion that while initial vaccinations would be successful in ending the Covid pandemic, they are unlikely to be effective against re-infection and completely eradicating SARS-CoV-2, the virus that causes Covid-19. Instead, they said, the maintenance of immunity will be dependent on the continued circulation of the virus in a population.
