Norfolk and Waveney has seen a drop-off in the number of coronavirus vaccines administered during the latest week-long period.
Fresh data released by NHS England shows 419,439 people living in the area had received a first dose of the jab by March 7.
It means a total of 35,253 initial shots were given out over the preceding seven days, compared to 45,454 in the previous week - a decline of 22pc.
Norfolk and Waveney CCG, which has been leading the rollout, said the recent drop was down to vaccine supply which is "expected to increase significantly from next week".
It added that some of the reduced supply had been used for second doses.
