It has been confirmed that the COVID-19's mutated strain came into South Korea. Since VUI-202012/01 infects 70 percent faster than conventional viruses, it means that the mutated virus will infect people 70 percent more than COVID-19.


the process of vaccine is to inject a COVID-19 vaccine. Antigenic components of vaccines enter the body and stimulate immune cells. Neutralized antibodies that can remove the virus from stimulated B cells. If the COVID-19 enters through the respiratory tract, it will be eliminated by neutralizing antibodies in the body. Using a vaccine platform can help developing vaccines fast. There are lots of ways to make vaccines. First is the virus Vector Vaccine. It encourages immune responses by injecting surface antigen genes from the COVID-19 into other viral. The second is Inactivated vaccine. Inject the extinct COVID-19 virus into the body to induce an immune response. The third is DNA Vaccination. Injecting surface antigen gens from the COVID-19 to produce surface antigen proteins in the body to induce immune responses. Fourth is RNA Vaccination. Injecting surface antigen genes from the COVID-19 into RNA form to produce surface antigen proteins in the body to induce immune responses. Making a Vaccine takes at least five years with an average of ten to twenty years. However, COVID-19's vaccine took only less than one year because the first COVID-19 strain does not mutate much. Second, humans have reached the point where we have a variety of antivirus development platforms. The third reason is that regulatory agencies like the FDA gave us permission very quickly.


▲ How vaccine works


The South Korean government has decided to purchase 10 million doses of vaccines from AstraZeneca, while in Huiza and Moderns, they purchased 10 million each, and 4 million in Jansen. South Korea has expressed his intention to participate in the Kobax and has secured 10 million doses of vaccine so far, A total of 44 million vaccines have been obtained through Kobax and four global pharmaceutical companies. there are a lot of concerns about side effects because the vaccine was made in a short period of time. However, we have to know that vaccines protect not only you but also your family. Also, the side effect of the vaccine is divided into four grade. Grade 1~2 is safe, but from Grade 3~4 is dangerous. However, COVID-19 does not pass over Grade 1~2. Expert says that people do not have to worry although you have headache or fever. That means that your immune systems are working.


▲ Vaccine of COVID-19


Expert says that COVID-19 will not end until November when people will get mass immunization. Since then, sporadic trends will continue to occur, but they believe we can go back to our daily lives by 2022. Still, COVID-19 will continue to occur, so people should still get an award for it until we all get the vaccine and get an antibody.
