So the spike protein is how Wuhan Virus infects humans right?
And the Moderna and Pfizer vaccines target the spike protein. And they'd be ineffective if the virus evolved and changed the spike protein
But if that spike protein changed, wouldn't it no longer be able to infect humans? In my mind that would be like changing the ridges on a key
Is that why the headlines about vaccines losing efficacy are never about Moderna and Pfizer? Because they did it in the smartest way?
