I'm vaccinated, and I even volunteered to participate in phase 1 booster vaccine trials. Articles like this are flamebait. The title is likely wrong, for starters. At a baseline, naturally generated antibodies/t-cell response almost always targets more than just the spike protein (ie nucleoprotein regions, etc). These often make them effective against a lot more variants, as those regions are much more preserved than the spike protein. Duplicating this response is the whole goal of the 2nd generation vaccine programs NIAID and others are running - to generate the same kind of response as a backstop against variants (it has a secondary goal of needing less dosage to vaccinate people). We are trying to better mimic the response the human body gives naturally. Natural response also lasts a long time (in effectiveness), too: https://www.nature.com/articles/s41586-020-2550-z https://www.nature.com/articles/s41586-020-2550-z "Next, we showed that patients (n = 23) who recovered from SARS (the disease associated with SARS-CoV infection) possess long-lasting memory T cells that are reactive to the N protein of SARS-CoV 17 years after the outbreak of SARS in 2003". 17 years. (Additionally, to the earlier point, lots of people infected with earlier SARS-COV variants appear to have an effective immune response to SARS-COV-2, because the natural generated response targeted preserved-between-viruses regions) Now, this doesn't mean that you shouldn't get vaccinated if you were infected - in fact, the strongest immunity that is seen from people who were infected and then vaccinated. This appears to generate a very strong, very effective response. But this "hunting with a shotgun instead of a sniper rifle" stuff is just stupid. So is citing 2 studies that say different things and saying "therefore i've proven natural immunity is unreliable" Any real discussion about vaccination vs natural immunity would have to go into CD4/CD8 response, what regions are targeted/preserved in mutations, etc. IMHO These kinds of articles do a lot more harm than good, because the misinfo in them is easy to discover, and that convinces people even further of conspiracies. They take an area where science is actually trying to figure out the answers (we aren't all that good at understanding the immune response), and pretends we know. That isn't going to help get people vaccinated.
