It may take several months or even years for researching and developing neutralizing antibodies against 2019-nCoV infection. One of the rapid approaches is to evaluate the currently available SARS-CoV neutralizing antibodies with cross-neutralizing and protection activity against 2019-nCoV infection. We have shown that SARS-CoV S-RBD-specific neutralizing mAbs and sera could cross-neutralize bat-SL-CoVs, such as bat-SL-CoV-W1V1 and bat-SL-CoV-SHC014 [13], suggesting that they may also cross-neutralize 2019-nCoV. Once identified, these cross-neutralizing antibodies can be promptly developed for urgent prevention and treatment of 2019-nCoV infection.
