I am rather rushed so have not had time to study this paper closely, but some factors need to be thought of.
The study group and the controls did not enter the study before the jabs were started, but afterwards. This could have been a confounding problem.
The two groups were not stratified into similar risk groups with the age difference being significant.
Cancer is a long term illness so the short follow up could confound the results.

More studies need to be.
