We read with great interest the report by Tampe et al regarding their patient with granulomatosis with polyangiitis on rituximab who developed a serological response to SARS-CoV-2 and attenuated viral spread only after B cell reconstitution.1 This is an important observation, which is logical and further supports the recommendations to time the SARS-CoV-2 vaccine towards the end of the rituximab cycle and, if possible, to delay rituximab until 2–4 weeks after the second SARS-CoV-2 vaccination.2 3 While we agree with the authors that waiting for B cell reconstitution might improve response to the SARS-CoV-2 vaccine, patients on rituximab can have prolonged B cell depletion (as seen in this case) lasting months or years4—making this strategy impractical for many patients. In addition, it appears that the SARS-CoV-2 vaccines induces both B and T cell responses,5 although this remains incompletely understood. Given the urgency of the pandemic, timing the vaccine with rituximab dosing intervals rather than B cell reconstitution is likely a better strategy for most patients. Booster vaccinations will also likely need to be evaluated in rituximab-treated and other immunocompromised patients, as such strategies may be helpful in overcoming inadequate vaccine responses.
