Several companies are working as quickly as possible to develop a safe and effective vaccine, which has been viewed by some as necessary for lockdowns to end and schools to reopen. While a vaccine may significantly reduce the risk of serious disease from the novel coronavirus, social distancing and face masks may still be a part of life, said vaccine developer Maria Elena Bottazzi.
“They automatically are going to say, ‘oh great, I’m just going to get my little vaccine, and I can go back and do exactly the things I was doing last year,'” Bottazzi told Business Insider. “That is absolutely not true.”
Ideally, Bottazzi said, a vaccine would give sterilizing immunity, meaning it would totally prevent people from becoming infected. Many vaccines don’t reach that level of effectiveness, however, and only reduce the chance of developing severe symptoms of a particular disease.
