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 3.7 million adults in Ireland, and we are vaccinating people at a 7-day average rate of around 3,376 doses per day.

This means it will take -131 days to vaccinate 95% of the adult population. The projected herd immunity date is Thursday, June 17, 2021.

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