Some studies have shown immunity from infection may only last several weeks in some individuals, whereas vaccination has been shown to last much longer and more reliably.

This is misleading, it conflates the presence of antibodies with immunity. There is no reason to believe immunity is not durable; a strong immune response to related coronaviruses (e.g. SARS-CoV-1) lasts decades. Antibodies are only generated in response to infections, and disappear after the infection has passed at varying rates based on a number of factors. People have no antibodies circulating for most things they are immune to. It is expensive to produce antibodies unnecessarily.

this is completely unfounded comment there are varous studies showing most of the infected people have immunity at least for 7-8 months, while we don't have any studies about how long last immunity after vaccination, for what's worth it can last less than immunity from infection yet people are shouting vaccine good, get it, get immunity and completely ignore the fact we should measure antibodies of vaccinated people while same people will shout oh if you were infected you are immune only for short time, I mean if you work for pharma lobby I can understand it, but are people really that trusting to pharma lobby, I remember also talking with doctors long before COVID how long last vaccination effect, they will tell you easily twice as long time as pharma company selling the vaccines, the reasons are obvious Study from Italy - only 3 out of 162 symptomatic infected didn't have antibodies after 8 months https://www.thelocal.it/20210511/covid-antibodies-last-8-months-after-infection-italian-study-finds/ https://www.thelocal.it/20210511/covid-antibodies-last-8-mon...
