The Food and Drug Administration on Monday issued new guidelines amid the emergence of new coronavirus variants for medical product developers. The regulatory agency said it was ‘committed to identifying effective ways to adapt medical products’, which are currently in the factory, or which are already authorized to use emergencies to address the variants.
“We know that the country is eager to return to a new normal and that the emergency of the virus variants raises new concerns about the performance of these products,” said Dr. Acting FDA commissioner Jane Woodcock said in a news release. “By issuing these guidelines, we want the American public to know what we are using to combat all the tools in our toolbox to fight this pandemic, including the twisting movement as the virus adjusts. We need to arm healthcare providers with the best available diagnostic, therapeutic and vaccines to combat this virus, we remain committed to bringing these life-saving products to the forefront.
Dr Rochelle Walensky, director of the Centers for Disease Control and Prevention (CDC), had earlier warned that the variant could jeopardize progress in the fight against coronavirus. Dr. Anthony Fauci, the country’s leading expert on infectious diseases, said the emerging mutations should be a wake-up call for those developing vaccines to stay alert.

Several companies have already begun research into adjustments to vaccination formulas or possible stimuli if the variants affect efficacy.
The FDA has said it will continue to monitor the situation and update plans as more information becomes available. Regarding vaccines, the agency said that if a product that has already received permission for emergency use is needed to address the variant, it is recommended that the efficacy assessment be supported by data from clinical immunogenicity studies, which assess the recipient’s immune response. with virus variants. induced by the modified vaccine against the immune response to the authorized vaccine.
The FDA also encourages manufacturers to study the vaccine in non-vaccinated people and in people who have previously been vaccinated with an authorized vaccine.

“Finally, the guidelines state that further discussions will be needed to decide whether modified COVID-19 vaccines may be approved in the future without the need for clinical trials,” the FDA said.
Dr Greg Poland, an infectious disease expert at the Mayo Clinic, stressed to Fox News that the lead is not binding, meaning it is still subject to change.
“I like that [the FDA] has made efforts to ensure that people understand that this is non-binding guidance, “Poland said, adding,” what I would like to see is that we do not yet have enough information on the immunology of these variants and that we have people who fit into immunologically different classifications. due to illness or vaccine, and we may need to be more nuanced in our requirements for amplifiers in such situations. ‘
The agency has meanwhile already issued a safety warning to test that the genetic mutations could potentially affect the performance of the test, and has already identified several tests that could be affected.

The guidelines also provide recommendations to test developers, such as considering the potential for future viral genetic mutations during the design of their test, and conducting their own routine monitoring to evaluate the potential impact of new and emerging viral genetic mutations, which: may be the basis of viral variants, over the performance for molecular, antigen and serology SARS-CoV-2 tests, ”the FDA said.
As for the therapy, the agency said it is aware that some of the monoclonal antibodies authorized for COVID-19 patients are less active against variants. Updated guidance “provides recommendations on effective approaches to the generation of non-clinical, clinical and chemical, manufacturing and control data that could potentially support an EUA for monoclonal antibody products that can be effective against emerging variants.”
