Why is the vaccine roll-out plan being changed?

It's mainly down to supply and Chief Medical Officer Tony Holohan's advice that people aged over 70 get the Pfizer and Moderna vaccines instead of the AstraZeneca shot because of a lack of available data on its efficacy for people in this age bracket.

What does this mean?

Measuring vaccine efficacy allows doctors and scientists to determine the reduction of Covid-19 in inoculated groups compared with unvaccinated ones. Studies to date do not include enough data on older people who received the AstraZeneca vaccine in trials for Dr Holohan to recommend it be used for over-70s.
