Pfizer and Moderna may provide lifetime protection against COVID-19

Christian Fernsby |
A new study has suggested the Pfizer and Moderna vaccines could provide lifelong protection against COVID-19 for people who have already been infected with the virus.

The mRNA jabs can provoke an immune reaction that can protect people for years, Washington University researchers found.

They said Covid survivors’ immune cells recognised the infection, which can still be found in bone marrow eight months later.

After looking at other research that demonstrated memory B cells could get stronger 12 months after initial infection, they concluded immunity to the virus could be lifelong if someone received a Pfizer or Moderna vaccine after getting the virus.

Immunologist Dr Ali Ellebedy, who led the study, and her team could not say if someone who received the mRNA jabs and had not previously been infected was protected in the same way.

The study included 41 Covid survivors who had been fully vaccinated with Pfizer or Moderna.

Ellebedy said: ‘It’s a good sign for how durable our immunity is from this vaccine.’
