From this it would appear that the older the Vax Lot the more deaths. I think that the numbers of deaths against the newer vax lots will rise as more people succumb.

But I also think it most likely that after the initial high reports of deaths that most doctors were told not to report them on the system.

I am not certain but the middle letter of the Vax Lot code appears to perhaps represent a 4 week period of the year. This is followed by the year itself.

A - M = 13 periods of 4 weeks (total 52 weeks)

e.g.

039K20A = Manufactured between Oct 7 and Nov 3 (2020)
036A21A = Manufactured between Jan 1 and Jan 28 (2021)
039B21A = Manufactured between Jan 29 and Feb 25 (2021)
014C21A = Manufactured between Feb 26 and Mar 25 (2021)
