B-cell immunity to SARS-CoV-2 lasts eight months: Monash study

The findings bode well for long-term vaccine protection in the future, researchers say

Patients who have recovered from COVID-19 appear to maintain cellular immunity to the coronavirus for at least eight months, an Australian study shows.


Investigators from the Alfred Research Alliance in Melbourne reported that despite a decline in SARS-CoV-2 antibodies after primary infection, virus-specific memory B cells continued to provide “long-term” protection.

Lead researcher, Associate Professor Menno van Zelm from Monash University, said it also helped explain why there had been so few cases of
