Abstract

We have vaccinated 392 patients with two doses of mRNA COMIRNATY vaccine with an overall antibody response of 70% (best in cMPN, worst in CLL). We have then vaccinated 80 patients who did not achieve seroconversion or were low responders with a third dose of COMIRNATY vaccine. Our first results show promise, especially for patients on anti-CD38 therapy.

Keywords: 3rd dose; COVID-19; coronavirus; haematological oncology; vaccination; vaccine.
