Niac changes hope to keep Covid vaccine rollout on track

The Pfizer vaccine has made up the bulk (74%) of vaccines administered to date, followed by AstraZeneca (21%) and Moderna (5%), with Janssen only now coming into use.

This week has seen significant changes to the Covid-19 vaccination programme and what vaccines will be made available to people under the age of 50.

It has been hard to keep pace with the many changes already made to the programme over the past four months given the logistical challenges, ongoing supply issues, and some concerns over rare and unusual blood clotting incidents, all of which put Government vaccine targets out of reach.
