The Director of Food and Drug Administration approved last night (Friday) the use of the third vaccine dose of the Modern and Pfizer company for people who are depressed by the immune system.
The change in FDA regulation is solely for patients who have failed to respond immunologically to the virus even after receiving the first two vaccines, in the hope that it will provide them with the required level of protection.
However, according to the Centers for Disease Control and Prevention, about 2.7 percent of adults in the United States have not been infected with corona, including organ transplant recipients, certain cancer patients, and HIV-infected people.
"The action allows doctors to boost vaccines for immunosuppressants who need additional protection," said FDA representative Dr. Janet Woodcock, emphasizing, "Other people, who are fully vaccinated, are properly protected and do not need the additional dose of the vaccine at this stage."
As mentioned, the FDA change does not apply to the general population, such different doses will only be given if it is proven that protection against vaccines in the general population falls below a certain threshold, although scientists have not yet determined the exact threshold.
"The directive will change if they see that the country's protection against the virus in the general population drops to a critical level," explained Dr. Anthony Pucci, head of the National Institute of Allergy and Infectious Diseases, stressing that those who receive the vaccine now have never responded well to the vaccine.
Today a group of independent CDC advisors will discuss the approval of the FDA's amended emergency use.
