The authors did not observe full sterilizing immunity, as four of nine animals had detectable levels of viral RNA in the upper respiratory tract after challenge, although the levels declined rapidly and viral RNA was detected in only two BALF samples very transiently; protection correlated with strong humoral responses63. Virol. We now know that many neutralizing antibodies elicited by SARS-CoV-2 infection bind to the RBD and prevent its interaction with ACE2 on host cells, effectively neutralizing the virus. However, a caveat was the frequency of pre-existing immunity to Ad5 (anti-vector immunity), which correlated with poorer T cell responses in vitro59. Broader neurological complications were described in a retrospective study of 214 patients with COVID-19 in Wuhan, which found that 78 (36.4%) of these had neurological complications, with acute cerebrovascular disease, conscious disturbance and skeletal muscle injury being the most frequent complications in severe cases35.
