Modern COVID vaccine, produced in two days! How was it possible News, foreign news Freedom

Nearly 95% effective, much like its Pfizer / BioNTech-made “brother”, Moderna’s Covid vaccine was developed in 48 hours, according to US media.

Extraordinary as the moment of “design” is when it was done: in January, when a large part of the world population had not even heard of the new coronavirus “.

On 11 January, Chinese researchers sequenced the genome of the SARS-VOC-2 virus and the data, made public, also reached the Moderna researchers. On January 13, the team of scientists involved in the project already had the raw material for the vaccine.

It is true, after the initial phase the testing phases followed, not a few, not fast and not at all easy, but the hardest part was done, and the months of waiting for the answers to the questions “is it effective? Is it sure?” ” they have paid.

The first vials of anti-Covid serum were ready on February 24, and on March 16 the first dose was administered to a volunteer enrolled in the vaccine testing program produced by Moderna.

The secret of speed

The rapid development of this serum before was made possible by the technology on which Moderna bet: the mRNA vaccine, or rather the messenger of ribonucleic acid (RNA)

MRNA vaccines provide a genetic sequence that contains one or more antigens, selected to produce an immune response. Basically, the substance – the messenger – enters the body, then the cell, where it decomposes and causes an immune response from the body if the presence of the virus is detected.

MRNA vaccines have a high efficacy rate, low cost, and rapid development.

By comparison, “classic” vaccines, which use a single dose per injection and are considered safer because the technology has been around for over 30 years, are weaker and may cost more.

Modern pioneering mRNA technology. Pfizer / BioNTech, Sanofi and Novavax developed antiCovid sera using the same technology.

Moderna is currently preparing documents to ask the Food and Drug Administration (FDA) to authorize its Covid vaccine for emergency use in the United States. Pfizer has already taken this step.
