"Hack" might be the wrong word. The mRNA strain elicits a response from your body, causing it to create a molecule that makes you resistant to the virus. This is compared to actually giving you a small dose of the virus so your immune system can "learn" the characteristics of the virus to protect against it.
That's the same thing a cold virus does. It releases RNA into your cell and your cell responds by creating more cold viruses. The mRNA doesn't seem to be the issue with the vaccines, first Moderna and Pfizer use nanolipids to deliver it and it does not stay in the injection site and secondly the spike proteins aren't supposed to be released into your blood stream but they are, and thirdly the spike proteins are more inflammatory than the intact virus (although with a natural case of covid spike proteins cleave off also causing inflammation and myocarditis).
With a traditional virus your immune system's adaptive immunity learns how the virus proteins are structured so it can recognize it (and similar strains) in the future. With the mRNA vaccines your immune system never learns to recognize the virus, which is why people with Covid are having far fewer problems with the Delta variant compared to those who just received the mRNA vaccines.
It learns to recognize the spike protein and produces memory cells for them, but the spike is the most quickly mutating part of the virus. People with natural immunity will have memory cells and antibodies for all parts of the virus. I don't know if there's a legitimate reason they made the vaccines only produce the spikes but it sure does look like planned obsolescence from the outside.
