People in their 30s will be invited to register for the Covid-19 vaccine from next Monday.
On the same day, qualified pharmacists will be allowed to start administering jabs.
Pharmacists are aiming to vaccinate around 140,000 people over 50 who have not yet registered.
One thousand pharmacies will administer the Johnson & Johnson vaccine for remaining people in the over-50 cohort. And 350 pharmacies will assist Vaccination Centres to administer Pfizer vaccine in communities that are distant from the nearest centre.
The Covid-19 vaccine portal will open to people between the ages of 35 and 39 first.
