Someone more local to Waterford than me might be able to shed some light, but I believe Ireland used significant numbers of J&J single dose vaccines to speed up initial rollout.
My understanding it that it had reduced efficacy against infection initially, which could be even more pronounced since Delta became dominant.
- Macha 5y agoJ&J was the initial vaccine planned, as its weaker effectiveness against spread of Delta was discovered, they moved to favouring Pfizer and Moderna. While there was a decent rollout of J&J prior to that, the biggest group of J&J vaccinations was after they made that decision, they gave young people the option of going to a chemist to get a J&J vaccination ahead of schedule to deplete their stock while the regularly scheduled rollout continued with Pfizer and Moderna. I think people who originally got J&J did get the option to get Pfizer later.
- ac2u 5y agoThanks for filling in the details. The article would be more interesting if it was able to include a breakdown of the types of vaccines in the population for the period of time it's referencing.
