They used the typical methods of normalization, even went beyond that. But I don't think normalization can make these two groups identical to the point of making CI: 1.11-1.37 reliable, see picrel, double the prior cancer patients vaxed vs unvaxed, 50% more for most other major diseases. But it's good that someone tries at a higher level than posting an excel that is barely past per capita, it's absolutely impossible that vaccines don't have heavy side effects.
