According to the genomics firm Helix, the delta variant of the coronavirus is spreading in pockets of the United States where the vaccination count is low. Helix sampled 20,000 cases from over 700 different counties in the United States and found that the variant is growing much faster in under-vaccinated counties. William Lee, the vice president of science at Helix says, “Delta is driving surges around the world, and I suspect it’s going to be the same here.”
Helix data also suggests a different variant, the gamma variant, is evading vaccines and is more “prevalent in counties with higher inoculation rates”. This data has not been subject to peer review and is set to be published.
According to the data from the CDC about 45% of Americans have been fully vaccinated. The same data shows that in 482 counties across the US, less than 25% of that population is vaccinated. Helix’s Lee said, “The alpha variant has been the dominant strain in the U.S. But the gamma and delta have gained a strong foothold and may soon push alpha out.”
