These are not single variable things that are simple to analyze.
I understood Ollinger to be implying that vaccination is helping with cancer rates.
If cancer diagnosis rates were declining, this would support his argument.
If cancer diagnosis rates are instead rising, it could refute his argument. Or it could mean nothing and be attributable to other factors, as you say.
Ollinger made an interesting observation, but it would be a shame if we got side-tracked into thinking flu vaccines are good for us because they lower the risk of cancer.
