I wouldn't bother commenting if I were hallucinating figures. There is no figure 4a.

If you look at figure 4 in the supplemental material you also see, per your expertise, that covid vaccine protects against traumatic injury. However even adjusting for the protective effect against traumatic injury there is still quite a large protective effect against all-cause mortality. So the beneficial effect of the vaccine is not solely caused by its protective effect against traumatic injury.

Or it could be, bold proposition I know, that there is a difference between the groups that both protects against traumatic injury and protects against all-cause mortality, independently of the vaccine.
