COVID Immunity Falls After Four Months Despite mRNA Booster: CDC

'People who had received third dose of the mRNA vaccine were better protected from the worst of COVID-19.'

A nationwide study by the US CDC has confirmed that protection from severe COVID falls significantly within four months of getting a third vaccine shot.

The study published on 12 February indicates that, just like immunity reduces gradually after the second vaccine shot, it falls similarly after the third vaccine as well. What does this mean?

In a nutshell, you're very likely to need multiple and possibly scheduled vaccinations from COVID-19, if you want to protect yourself from the worst effects of COVID-19.
