> They say natural resistance is better or equal than from the vaccine

Who are "they" and what exactly are "they" saying? I think there is a consensus that even if you had the disease, it's wise choice to get vaccinated. Protection from vaccination and recovery is better than protection from only one of them, as far as I understand it.

What math?

> Also people said the regular flu does not exist anymore

Seasonal flu will of course continue to be a thing. But restrictions obviously meant that last years flu season was kept low in many places around the world. This however means that there could be a worse wave coming this year (and it has happened too in many places - we are in the flu season in the wintery part of the world now). In places with good mask adherence, no big public events and so on, obviously ALL respiratory diseases will have a harder time spreading. But these restrictions are - hopefully - temporary, The flu will be fine.

Can't speak for the whole world, but in Canada my experience is that they're not testing for the flu anymore. Only COVID. In years past if you went to the doctor during flu season they'd do a throat swab for flu. Now it's only for COVID.

I know lots of people who were sick but only tested for COVID. One of my friends was out of work for a month with a bacterial infection they missed for 2+ weeks because they only tested for COVID....

I never heard about testing for flu in the past either, except when admitted to hospital with severe disease. There is "monitoring" i.e. some random statistical testing only as far as I know.
