[However, there is confusion over the source of the delay
with a Government source blaming a range of 'production issues'.
The source revealed that this included the need to
re-test a large batch of the vaccine, although they
did not specify from which manufacturer.
They also suggested there was an issue with
AstraZeneca's production overseas,
resulting in fewer jabs being delivered
in April than initially planned.
This was backed up by another government source
that claimed the shortages were related
to the late delivery of five million doses
of the AstraZeneca jab being manufactured in India.
The Serum Institute was due to send
10 million doses to the UK - yet only half have arrived.
Another senior government figure has suggested
AstraZeneca is 'late' with doses. ]
