Something to ponder RE Santa

[Donnamarg323]

During the 1918 Spanish flu pandemic, Santa was sidelined, as reports at the time noted Santa's appearances at department stores were canceled. This proves Santa can get the flu, so it is important for both Santa and children to get the flu shot and the COVID-19 vaccine when it becomes available.

So my question is this.....Does Santa really exist or how the hec does he catch the flu with that immune system of his?
