4 million people could be vaccinated in Ireland against Covid 19 by the end of September.
The Health Minister has sent updated projections saying 7.5 million doses should arrive between April and the end of September.
Stephen Donnelly already said 700,000 people should be vaccinated by the end of March.
Dr. Denis McCauley is Chair of the Irish Medical Organisation's GP Committee, he says the vaccine rollout will speed up significantly once doctors are allowed administer it.
"If we have enough Astrazeneca vaccines in our GP surgeries we will be doing a million every six weeks at the very least.
"It is to do with the actual vaccine that is available - once we get the proper vaccine we will be the primary vaccinators."
