Stocks of the 'flu vaccine are building up in GP surgeries and pharmacists this week in preparation for the winter ahead.
Last winter, the number of patients opting to have a 'flu jab in their local pharmacy doubled with many getting vaccinated against the illness for the first time.
Pharmacists have been allowed to give the vaccine for the past two years, ending the monopoly previously enjoyed by GPs.
A new report found the 'flu jab service provided by pharmacists is operating effectively "with no quality or safety concerns".
The report was carried out by the Pharmaceutical Society of Ireland, which is responsible for regulating pharmacists.
It followed concerns that arose in the first winter season pharmacies started giving the 'flu vaccine when a number of patients did not get sufficient doses.
However, the report said last winter the service operated well and more than one-quarter of patients attending the pharmacies for the vaccine had not been vaccinated before.
A majority of these should have been getting the jab because they were in 'at-risk' groups due to illness or age.
More than half of pharmacists who provided the vaccine gave the jab to their own staff, which helps reduce the amount of 'flu circulating.
Pharmacies are to begin stocking up on the 'flu vaccine for this winter. It is expected to be widely available from Friday onwards.
The cost of getting the vaccine varies per pharmacy and can range from around €15 to €20. GPs have had to bring down their fees to compete and can charge from around €25 upwards depending on the patient.
The report said focus groups of patients cited the accessibility, flexibility and cost of the service in pharmacies as attractive to them.
