Interested in how a vaccine actually works.
As far as I understand, vaccines don’t stop viruses from spreading but they give a person immunity so that they can fight off the virus should they actually become infected with it which means their symptoms (if any) are likely to be mild and death is less likely.
Am I right? So in other words, when the vaccine becomes available worldwide and when the pandemic is over, covid will still spread amongst people but it just won’t be as severe and deadly anymore?
