Will the UK authorise fourth doses of Covid vaccines for healthy adults in 2022?

In September 2021, the UK's health service started its "booster" campaign, offering third jabs of the Covid vaccine to all adults in the UK.

But will Covid vaccine boosters become annual events, like flu jabs? Other forecasters have asked that question of the US: this asks it about the UK.

Will the UK authorise fourth doses of Covid vaccines for healthy adults in 2022?

This will resolve positively if the MHRA authorises a fourth dose for the entire UK adult population before 1 January 2023.
