Came across this article which was a little more optimistic about our complex immune systems.
From the article:
But the complex human immune system response might still allow the body to block the virus from a variety of other directions. While the mutation could foil antibodies focused on that particular piece of the spike protein, it won't affect antibodies trained to look for other parts of the virus.
"It is analogous to a key and lock. If that lock changes, maybe the key can't get in," said Scott Hensley, an expert in immunology and molecular biology at the University of Pennsylvania.
"But imagine this not as a single door into a room, but 10 different doors. There will be nine other keys that will be able to get you into that room."
That's because people usually make more than one type of antibody against a virus.
"The human immune system is complicated, and it is likely that most of us have antibodies against multiple targets," Hensley told CNN. "It is likely these variants are not going to have a huge effect on the vaccine response."
Microbiologist Jesse Bloom of the University of Washington and colleagues found strong evidence this is the case.
In a preprint study posted Tuesday -- one that has not been peer reviewed or published in a scientific journal -- they described how the immune cells and antibodies in blood taken from 11 different people responded in many different ways to mutations in the virus.
For a few people, mutations allowed the virus to escape so called neutralizing antibodies, which stop the virus from getting into cells. But in blood serum taken from others, even mutant virus was overwhelmed by the variety of antibodies produced.
Scientists worry that mutated variants of coronavirus might evade the protection provied by vaccines. Here's how that might happen - and why some experts think it's not a major risk.
