The American company Modern is testing the mRNA-1273 vaccine on teenagers between the ages of 12 and 18 years.
Good news for the corona vaccine for children
American company Modern has begun a mid-final clinical trial of its Corona vaccine on children between 6 months to 12 years old.
In this study, the safety and efficacy of injecting 2 doses of its produced corona vaccine, mRNA-1273, over a period of 28 days, ultimately on 6,750 children in the US and Canada review.
The vaccine was previously licensed for emergency use for people 18 and older in the United States. Modern is currently testing the mRNA-1273 vaccine in 12 to 18-year-olds in a separate study that began in December.
A recent study of children was done in collaboration with the US National Institute of Allergy and Infectious Diseases (NIAID) and the Advanced Biomedical Research and Development Organization (BRADA).
Pfizer-BionTech and Moderna have used the new "Messenger Arena" or "mRNA" technology to produce the Covid-19 vaccine. These two vaccines are the first vaccines produced and marketed using this method.
In the traditional method of producing a vaccine against viral diseases, the virus or its protein components are commonly used to stimulate the human immune system. Then, when the body is next exposed to that particular virus, it produces a specific antibody.
Opinion
But mRNA vaccines do not require viruses (although small amounts of the virus are used to sequence the genome and test the vaccine), but a part of the virus's genetic code enters body cells after injection And produces the horn protein of the virus. The immune system with the production of antibodies and immune T cells to fight the disease.
So when the body's immune system is activated, the horn proteins of the virus and the messengers of arenas are destroyed, but antibodies remain in the body for future protection.
The Modern American Biotechnology Company conducted experiments in early April 2016 to produce the Corona vaccine; Injecting the vaccine into mice, called mRNA-1273, prevented the corona virus from entering their lungs.
In May, experiments were conducted on humans, and results obtained on eight healthy volunteers showed that the vaccine is safe and can create a strong immune system in these people.
The US company conducted the second phase of mRNA-1273 vaccine trials in mid-June on 600 volunteers with positive results. The third phase of this vaccine trial was carried out in early July at 30,000 people.
The 1273 mRNA vaccine was developed in collaboration with the National Institutes of Allergy and Infectious Diseases, and its clinical trials have been carried out with the help of the US National Institutes of Health.
According to IRNA, the corona virus called "Kovid 19" was reported in mid-December 2019 in Wuhan city of central China.
The disease was previously known as pneumonia; But on 30 December 2019, the National Health Commission of China officially announced the outbreak of the virus in China.
At a conference on Wednesday, March 12, 1998, the Director General of the World Health Organization, Tedros Adhanam, insisted that although the term epidemic should not be used carelessly because of its sensitivity; But the organization's assessments identify the corona virus as a "global pandemic".
