Answer:
Whilst trials have shown several COVID-19 vaccines to have high levels of efficacy, like all other vaccines, COVID-19 vaccines will not be 100% effective. WHO is working to help ensure that approved vaccines are as effective as possible, so they can have the greatest impact on the pandemic.“We just don't have enough time to figure out how long these immune responses last for these vaccines,” Smith said. The New England Journal of Medicine published a report on Tuesday about Moderna's vaccine, saying it should offer protection from COVID-19 for at least six months.
