Citing preliminary research, the CDC said variables could be about 20% more transmissible. Some Covid-19 treatments may also be less effective against stress. However, the CDC did not say if the vaccines would stop working against them.
In laboratory studies, antibodies of vaccinated people seem to be less effective in neutralizing stress. But lower levels of antibodies may still be sufficient to protect against Covid-19, especially in severe cases. Immune cells can also help protect against disease – not just antibodies.
Concerns about antibody treatment
Still, health officials are concerned that some remedies may not even work against the variables, which are officially called B.1.427 and B.1.429. Scientists have been monitoring tensions in California for the past few months.
The agency expressed concern that the treatment, which is made by Eli Lilly and company and is called Bamlanivimab, may be less effective against stress.
A second Covid-19 therapy, a combination of Bamlanivimab and another drug, Ettevisamb, made by Eli Lilly, could still be ordered, officials said. Preliminary results show that drug addiction significantly reduces the risk of hospitalization and death. A separate antibody treatment made by Regeneron Pharmaceuticals was also not affected by HHS action.
Ally Lilly said Tuesday that it constantly monitors the Covid-19 environment for a variety of types and tests its therapies against a “wide range of variations and types”.
In a statement emailed to CNN, Ally Lilly said, “Our view has always been that additional antibodies from Lilly and others will need to be developed to take into account the evolution of the virus, including filling variables that may vary by country or state.” . ” On tuesday.
“In fact, this is the one that drove our work on Bamlanivimab and Attizvimab together and continued to advance our strategy.”
