- Close contact exposure to Sars-Cov-2 without infection.
From page 6: 'Close contacts who are Sars-Cov-2 exposed are often both NAT negative and antibody negative indicating that Sars-Cov-2 failed to establish a successful infection'. So the exposure generated memory T cells in absence of an infection. I wonder how quantitatively widespread in a population this would be ?https://www.researchgate.net/publication/350192067_Exposure_to_SARS-CoV-2_generates_T-cell_memory_in_the_absence_of_a_detectable_viral_infection
