New coronavirus variants spread throughout the United States, according to White House experts

(HealthDay)-New, more infectious variants of the coronavirus are beginning to emerge in the United States, but all remain vulnerable to the two vaccines currently distributed to Americans, Whitehouse COVID -19 The response team said on Wednesday.

As of January 26, 308 UK variants have been identified in 26 states, said Dr. Rochelle Warrensky, director of the US Centers for Disease Control and Prevention. This variant has been found in 47 countries so far.

This week, public health officials identified the first US case of a Brazilian variant of the outbreak in Minnesota, according to Warensky. The variant has only been found in five countries.

A third variant from South Africa has emerged in 20 countries, but has not yet been detected in this country, Walensky added.

“Recently identified variants appear to be easier to spread and more contagious, which can lead to increased cases and stress on already taxed healthcare systems,” Walensky said. He said.

However, these variants do not appear to be superior to either the Pfizer or Modana vaccines, said Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases and chief medical adviser to President Joe Biden. Said.

British variants “have very little, if any, effect on vaccine-induced antibodies,” Forch said.

South African variants that haven’t reached the US soil yet appear to be unresponsive to the vaccine, so they are “a little more problematic,” Forch said.

“But this is important, but still well within protection,” Forch said of South African stocks. “Even reducing the effectiveness of vaccine-induced antibodies by a fraction can still remain within the vaccine’s protection.”

Phase 3 clinical trial results are expected within a few days for the third COVID-19 vaccine produced by Johnson & Johnson, and Fauci said these results were more about the interaction of these mutations with the vaccine. He said he could provide insights.

“We plan to consider effectiveness not only in the United States, but also in South Africa and Brazil,” Forch said. “We will have some comparative effects that tell us where we are going [the South African] The pedigree is well established in the United States. “

The CDC is driving improvements in the gene sequence of new COVID-19 cases across the country, and public health officials are preparing to develop “booster” shots of existing vaccines that cover future mutations that interfere with vaccine-induced immunity. Has been done, Mr. Forch said.

“We will monitor in real time how the effects of antibodies induced by current and future vaccines affect their ability to neutralize these mutants,” Forch said. “When we see them moving towards more vulnerable parts, it’s time for us to trigger … in fact making the same vaccine version specifically directed against the relevant mutants. I will. ”
