Herd Immunity

How long will it take until enough people in Ireland have been vaccinated to provide full herd immunity?

For full immunity we should aim to vaccinate 95% of the population, though much of normal life should be able to resume earlier.

We can calculate an estimated date as follows. There are around 4 million people aged over twelve in Ireland, and we are fully vaccinating people at a 7-day average rate of around 3,450 doses per day.

This means it will take -91 days to vaccinate 95% of the adult population. The projected herd immunity date is Wednesday, October 27, 2021.

This estimate will be updated daily as more vaccination information is received.
