An effective vaccine against the coronavirus that causes COVID-19 is everyone’s hope for a real return to normal life. More than 100 teams of scientists around the world are working to develop and test a vaccine against the virus SARS-CoV-2 as quickly as possible. They’re employing a huge variety of strategies and technologies, including some that have never been used in an approved vaccine before.
“It’s a very fascinating and kind of impressive effort,” said Dr. Lynora Saxinger, an infectious disease specialist at the at the University of Alberta in Edmonton.
“It’s absolutely crucial.”
Even in countries that have had a devastating number of deaths from COVID-19, there is nowhere close to a level of “herd immunity” within the population preventing the disease from spreading exponentially if we go back to normal levels of social interaction, she said.
