Should we expect a 3rd wave of COVID-19 cases? Prof Tulio de Oliveira explains

While the number of coronavirus cases has been on a consistent decline, which is incredible news, most people are still suspicious. And why wouldn't you be, seeing as how, for the past year, just as things have been seeming to improve and the light at the end of the tunnel creeps closer, something pops up and knocks us back down. Today Prof Tulio is here to discusses whether or not we should be expecting a possible third wave. And as a follow-up, he also chats about the vaccine rollout and whether or not the vaccine has had any effect on the coronavirus numbers yet.
