Most pharmacies in Kerry will have a stock of vaccines to administer to those aged 18-34.
That's according to Jack Shanahan, of Shanahan's Haven Pharmacy in Castleisland.
Mr Shanahan, who is also a member of the Irish Pharmacy Union, says where pharmacies in the county have stocks, they will be more than happy to give them out.
People in that age bracket are also being encouraged to contact their local pharmacy directly to see if they have Janssen vaccines in stock.
The HSE website says just 10 Kerry pharmacies are available to offer vaccines, but Jack Shanahan says this is incorrect.
