A study by Monash University reveals people who have been infected by the COVID-19 virus have sustained protection against reinfection for at least 8 months.
If past studies were raising concerns whether the antibodies to coronavirus quickly wane, this study is the first one concluding the likelihood for vaccines to be working for long periods.
From a cohort of 25 COVID-19 patients, they found the existence of a specific cell within the immune system, the memory B cell, can recall if the virus was present in their system for up to 8 months after they were infected.
