Setting it Straight: Reinfection in COVID-19 – part one
Setting it Straight - Issue #23
Written by Nobel Laureate Professor Peter Doherty
Among the most frequently asked questions regarding immunity to the SARS-CoV-2 virus that causes COVID-19 is: how long does protection last? So far, that question has been raised mainly because people are wondering if they can contract this infection a second time. But, as vaccines are rolled out, there will be the added issue of vaccine efficacy and durability if, as seems likely, the virus continues to circulate at some level or other after widespread immunisation. As you go through what follows in the next essay or two, you might come to the conclusion that, whether or not you have had COVID-19, a regular vaccine boost could be a good idea.
