Vaccine booster campaign against Covid-19 being planned for the winter

The Business Post reports health officials will give people top-up jabs using single-dose Pfizer shots

The paper says NIAC will use available immunity data to decide when the revaccination campaign will begin. 
 
It's believed most mass vaccination centres will begin to close in the autumn, and the rollout will move to pharmacies and GPs. 

Professor of Immunology at Trinity College Dublin, Kingston Mills, says booster vaccines will be needed due to variants like the Delta strain: 

"That's the worrying thing for Ireland, you know, we're using a mixture of the Pfizer, Moderna and AstraZeneca vaccine that the Pfizer, Moderna are giving very, very, very, very good protection but not the same for the for the AstraZeneca vaccine unfortunately it's just really not quite as good as to the two when it comes to dealing with it after variant."
