Pfizer has been pretty explicit with their comments that the deliveries will still meet the amount required by the end of quarter. Perhaps the EU has end-of-month targets instead.

I'm just not that concerned about it personally. There'll be a political price to pay if it doesn't work out, as well as a contract violation price for the manufacturers. I don't expect I'll be able to get a vaccine until August at the earliest anyway.

I wish addressing climate change was covered with the same urgency by media (mainstream, niche, social, all of the above)
