Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said monoclonal antibodies, which stop the spread of coronavirus in the body, are part of a promising strategy to prevent serious illness from Covid-19.
Antibody-based drugs, antivirals and other antivirals in patients recovering are being investigated as early treatment, Fauci said. Its purpose is to prevent serious lung damage to patients Gilead Sciences Inc. Of remedicivir and anti-inflammatory drug Dexamethasone is administered.
“We’re very focused on treating early infections and, or, preventing infections,” Fawcett told the Journal of the American Medical Association. Interview Friday. “And that’s the vaccine bridge.”
FARC said that the U.S. against SARS-Covey-2. Vaccination may begin in November or December, however, it will take at least until the third quarter of 2021 to protect enough Americans against the epidemic virus to significantly reduce its risk. Fawcett said 100 million doses of the vaccine could be produced by December, with all six companies supplying the U.S. making 700 million doses by next April.
With no vaccine yet proven to prevent Covid-1, health officials must continue to come up with new treatments and measures to prevent the spread of coronavirus, said Professor Robert “Chip” Schulz, a physician at the University of California, San Diego. Is studying more potent versions of existing antivirals.
“At best, we have an oral antiviral drug that you can give to more people during illness,” Schulz said. Vaccines may not be 100% effective, “which is no better than anything, but we still have to rely on drugs and behavioral changes for a long time.”
Blockbuster studies published by the Journal of Science on Thursday showed that about 14% of complex Covid-19 patients have defects in levels of a substance called interferon that helps protect the body against viral pathogens.

This finding opens up the latest strategies for identifying high-risk patients and treating them with interferon infusions or, in some cases, removing interferon-blocking antibodies from their blood in a process called plasmapheresis.
Interferon, which has already been studied in dozens of clinical trials, may improve the effectiveness of antiviral drugs if they are given early in infection, according to Stanley Pearlman, Professor of Microbiology and Immunology at the University of Iowa in Iowa City, who has studied coronavirus for 38 years.
Infection with coronavirus-inactivating antibodies can reduce the amount of virus in infected patients at the onset of the disease and inhibit the immune system, said Thomas File, a physician and infectious disease president at Acron, Ohio, Ohio. Illness Society of America.
“Monoclonal antibodies, a product made by cloning antibodies captured from a patient’s blood that were recovered from Covid-1, can also be given to nursing homes as a preventive treatment,” Foci said. Experimental antibody LY-Covy 555 from Eli Lilly & Co. showed some Signs of optimism in the trial in out patients, the company said on September 16.
“We have some cautious optimism that monoclonal antibodies may be an important therapeutic agent for early disease,” Fawcett said in Sept. 10. Online briefing for Massachusetts General Hospital staff. “We need something to keep people away from the hospital.”
‘Tricky Medicine’
Dexamethasone and similar steroid drugs, if given as early as possible during Covid-19 illness, can cause harm, said Shane Croty, a professor at the Center for Infectious Diseases and Vaccine Research at the La Jolla Institute in California.
“Steroids have certainly proven valuable in very sick people, but they are a difficult drug,” Croty said in an interview. The drug prevents part of the immune system from going “highwire” and causing harmful inflammation, as well as producing antibodies to part of the immune system to fight infection.
The problem highlights the need for treatment to fight the virus while supporting the immune system, and mixed and matched resins based on the body’s success in fighting infection, said Michael Osterholm, director of the Center for Infectious Disease Research and Policy. University of Minnesota.
“This is part of the dance with this virus,” Osterholm said. “You’re trying to take the best from the host and increase it, and take the worst host and suppress it.”
