Setting it Straight: Reinfection in COVID-19 – part two
Setting it Straight - Issue #24
Written by Nobel Laureate Professor Peter Doherty
Last week we looked at a well-documented case of reinfection (see Reinfection in COVID-19 - part one) with SARS-CoV-2. A Hong Kong resident who had COVID-19 and developed some symptoms tested positive again 142 days later when checked by PCR at the airport on his return from a business trip to Europe. That was not too concerning as he remained asymptomatic following the second experience, which clearly boosted his immunity. But what does it tell us about protective immunity in SARS-CoV-2 infection?
