It’s not just Delta – other coronavirus variants worry scientists, also
CNNCNN — Coronavirus variants are what keep Dr. Scott Lindquist, an epidemiologist for Washington state, up at night. According to the California Department of Public Health, Gamma accounted for 10% of all sequenced specimens in May, and “has been increasing in all regions of California.” “Public health officials are concerned about the Gamma variant and several other variants of concern, including Alpha and Delta, that have been increasing in frequency in California and may have moderately decreased response to some antibody treatments or be more transmissible,” the department told CNN in an email. “And right now the only effective treatment that we have if you give it early on is the monoclonal antibody, so if it’s going to escape the monoclonal antibody, that’s really problematic.” Hotez said the impact on immunity is linked to the mutations – three of them – that change the shape of the virus in the variant, making it harder for immune system proteins called antibodies to recognize and latch onto it. “The concerning part of all these variants, is that they keep appearing,” said Ramon Lorenzo Redondo, an infectious disease specialist at Northwestern University’s Feinberg School of Medicine. “When you’re dealing with states like Alabama, Arkansas, Mississippi – that part of the country where vaccine uptake is low – people there are very vulnerable to a more transmissible variant like Delta, if it takes off, Gamma.”
