The Spike Proteins Are Critical to the Infectivity of a Virus

Virus is like an enigma code. They hide the important bits, and they cover them with variable bits that changeit so that you to specifically to evade the immune system. Sometimes it does change the act infectivity or deadliness of the virus itself. The trick is being able to get spike proteins that are universal to even just all of the coved variance would be nice. And what if we could design one accine that would target all of the variants of sa cove too? And not only that, what if iy could also target murs and sars and even potentially other corona viruses that don't even exist yet as a human infection,. That haven't spilled over yet
