Covid-19 booster rates are stalling, prompting calls for the roll-out to get it's own shot in the arm.
In mid December, nearly 90 percent of people were double vaccinated.
After three months - the period they must wait for a third shot - only 73 percent of those eligible have had their third jab.
That's despite the booster being far more effective at keeping you out of hospital.
