>You need a significant infection which triggers a strong immune system response to build long term immunity.

I don't think this is true. I get the flu shot every year and have never had a strong immune response to it, yet I'm still immune to the major flu strains each year.

Point being, it's possible for your body to create long term immunity to a virus without suffering from a severe infection.

I am specifically referring to COVID-19 where we don’t have a vaccine. Vaccines fake a significant infection to get that same strong immune response. This is also why some vaccines require multiple doses over a short period.
