       how long does the protection last

       Little is known about the memory B-cell responses against
       MERS-CoV, apart from a recent study which demonstrated the
       persistence of anti-MERS-CoV antibodies in MERS survivors up to
       34 months (Payne et al., 2016). On the other hand, antibody
       responses against another closely related coronavirus, SARS-CoV,
       were not persistent, whereby a 6-year follow-up study did not
       detect memory B-cell responses in SARS survivors (Tang et al.,
       2011). It is likely that some of the B-cells differentiate into
       MERS-CoV-specific memory B-cells following infection or
       vaccination, but the longevity and protective efficacy of these
       memory B-cells against MERS-CoV infection or re-challenge remain
       unresolved questions (Du et al., 2016b; Perlman and Vijay,
       2016).
