I'm not sure if I'm right, but the way I read these stats is this way:
6.5% died within 12 hours
13% died within 24 hours (which includes the 6.5% from before, so only 6.5 died between12 & 24 hours after vax)
26% died within 3 days (the 13 % that died within the first day + a further 13%)
37% died within a week (26% in the first 3 days and 11% in the next 4 days)
61% died within 2 weeks (37% within the first week, 24% in the second week)
70% died within 3 weeks (61% within the first 2 weeks and 9% in the third week)
So all up 70% died within 3 weeks (the article doesn't say when the other 30& died, might have been much later)
0-12 hours: 6.5%
12-24 hours: 6.5%
Days 2&3:13%
Days 4,5,6%7: 11%
Week 2: 24%
Week 3: 9%
6.5
+ 6.5
+ 13
+11
+24
+9
= 70
