Delta attempting to brute-force its way past the human immune system

The Delta variant of Sars-CoV-2 seems to have taken a leaf from a computer hacker’s manual by attempting to brute-force its way past human and vaccine immunity systems by spitting out slightly mutated versions of itself almost on a daily basis.

Similar to cracking a password, brute-forcing means that the virus is trying every possible combination of variations to find the most effective one, and it’s doing it incredibly quickly. The most successful new mutations then become dominant through selection pressure.

Many of these new Delta plus variants are distinguishable only by a single mutation, but the brute-force technique the virus is now using represents the biggest threat to humanity so far, as we have no obvious means to prevent it.

For example, two weeks ago, we took a snapshot of Outbtreak.info that showed a big rise in the AY.3 Delta plus variant in the USA.

 

Now, just two weeks later, the AY.3 variant has already been supplanted by the AY.4 variant:

 

 

 

The number of Delta plus variants seems to be rising ever more quickly, each variant with its own individual key combination to try to pick the immunity lock. With no lockout mechanism for failed attempts, the virus can just keep trying until it succeeds.

Here’s a list of the Delta Plus variants so far, taking us up to AY.15, with many more to be added soon we’re sure:
