The corona virus is spreading rapidly around the world, but scientists around the world are developing vaccines against it just as fast. So far, several vaccines are in the experimental stages.
However, corona virus is being rapidly researched around the world. Researchers, from geneticists to virus experts, have been working to control the virus in a number of ways.
On January 21, Chinese researchers released the genome sequence of the corona virus. From that day on, researchers began working on a vaccine against it. The first vaccine to be tested on humans began on March 16.
According to the World Health Organization, about 200 vaccines have been developed so far, of which 44 have been approved for experimental use on humans.
Under normal circumstances, it takes years to develop a vaccine against a virus. The fastest vaccine to date was developed against the mumps virus, but it also took four years to reach clinical trials. Researchers working on a vaccine against the corona virus say they will bring some vaccines beyond the clinical stage to normal use within 12 to 18 months. The World Health Organization says that by 2021, two billion people will have been vaccinated.
So far no vaccine against corona virus is in common use in any country in the world.
Corona Week, Sino Week Biotech
Leading the race right now is Corona Week, a vaccine from the Chinese company Synovik Biotech. The drug has entered its third phase of testing and is being used on thousands of volunteers in Brazil, Turkey and Indonesia. It is said that this vaccine will be available in November. Although clinical trials of the drug are ongoing, China has allowed people at high risk to receive the vaccine in an emergency since the end of August.
BNT 162B2, Phaser Biotech
American German Pfizer and Biotech RNA Messenger vaccine. It is in its third phase of testing and is currently being tested on 44,000 people in various parts of the world where the coronavirus has spread. According to the vaccine company, it will be known by the end of October whether the vaccine is effective or not, while the necessary data on safety will be available by the end of November.
MRNA 1273, Moderna
Another RNA messenger vaccine was developed by the American company Moderna. Which is currently being tested on 30,000 people in the third phase. According to the results of the initial stages of this vaccine, antibodies were produced from T cells in both young and old people who used the vaccine. In a trial of this vaccine, half of the people have been given this vaccine, while half have not been given it. Or whether the vaccine was effective against the corona virus.
