mRNA booster vaccine confers strong protection against SARS-CoV-2 Omicron in cancer patients

A new preprint research paper posted to the medRxiv* server reports the induction of high neutralizing activity in these patients against the Omicron VOC with a booster dose.

5 Jan 2022

Time since COVID vaccination is a key driver of breakthrough Omicron infections

Published on the preprint medRxiv* server and awaiting peer review, the findings showed that the significant factor behind breakthrough Omicron infections is the timing from vaccination. The time between vaccination and breakthrough infections induced effective or cross-reactive neutralizing antibodies that neutralize Omicron after Alpha or Delta breakthrough infections.
