The great progress in the efficacy of Pfizer and Moderna vaccines against Coronavirus, and their innovation in record time, raises questions about the feasibility and safety of the two vaccines.
The chief epidemiologist in the United States and the president of the US National Institute of Allergy and Infectious Diseases, Dr. Anthony Fauci, explain to USA Today how scientists came up with these vaccines? And why is people’s trust in the vaccine the key to overcoming the epidemic?
Fauci states that “the confidence of the American public must be instilled in the safety and efficacy of the vaccine if its results prove it, and that this vaccine will be available to the broadest segment of people between April and July, which means that the United States will return to normal before the fall of 2021 “.
He said vaccine approval is not an easy process, as a specialized committee of the US Food and Drug Administration “FDA” reviews clinical trial data and makes sure of the levels of efficacy and safety it provides based on the current data.
Typically these are independent from the Commission, and do not follow any formal body or even company, and is made up of experts specialized in conducting such clinical trials.
And half of clinical trial participants must have passed the second dose of the vaccine for more than 60 days to ensure its safety or harmful effects, which usually appear within six weeks of the short term.
Fauchi, confirmed that he recently saw data from the clinical trial for vaccines, Pfizer Biontec, as the company had previously indicated that there were no serious safety effects on volunteers for clinical trials.
He explained that the independent committee of scientists of the “FDA” will meet at the beginning of December, to verify through real evidence the safety and efficacy of vaccines, and this meeting will be preceded by another analysis by the Food Administration, which will open the way to committee meetings.
After all-day committee meetings, it will present its recommendations to the Food and Drug Administration, which will include whether or not to allow the use of the vaccine? In addition to recommendations regarding the first group that should receive the vaccine.
On Friday, Pfizer and Biontec filed an urgent license application for their emerging coronavirus vaccine in the United States, as authorities have imposed new restrictions to contain the pandemic.
On Friday, US Secretary of Health Alex Azar announced that the American company Moderna, which is working to develop and distribute a large-scale Corona vaccine, could make a similar request from him.
Scientists created Moderna and Pfizer vaccines according to a technology that was adopted for the first time in vaccine history, called messenger RNA, or mRNA, to produce an immune response in vaccinated people.
According to this technology, vaccines deliver genetic DNA (mRNA) or (RNA) to the human body to convert cells into proteins that have protrusions that make antibodies similar to protrusions above the Corona virus.
In the case of the person who received the Corona virus vaccine later, Vstmay antibodies attack strong and effective exposure. And both vaccines are given in two doses, separated by weeks.
