Clearly compare the immunity from vaccination and being infected with COVID-19, which one has more?

It is of great interest to study

The infection has a chance of being seriously ill and hospitalized. than the side effects of the vaccine

immunity caused by vaccine measured at doses much higher than infectious Because it uses a large amount of antigens, especially mRNA.

Infection in nature can build immunity well.

From a study in America (Journal of American Journal of Public Health, 2023;113:96-104) there is interesting data.

Those who received the vaccine and those who were infected after a long follow-up. It was found that those who were vaccinated have a higher chance of being infected than those who were previously infected
