More than 90 vaccines are being developed to fight the coronavirus in the world. Researchers are testing various techniques. Some of these technologies are ones that were not used in pre-licensed vaccines. According to Nature, at least six groups have already started injecting Volunteers under the formula in safety tests. At the same time, others have started testing on animals. Nature's graphical guide explains each vaccine design. Information about these eight strikes of scientists on the coronavirus will be given in two installments.

The immune system in our body surrounds the specific APC virus and activates the T helper cell from its performing part. T-helper cells are capable of other immune responses: B cells produce antibodies that can inhibit cells infected by the virus. It is also capable of destroying viruses. Cytoxic T cells identify and destroy cells affected by the virus. Long-lived B and T cells recognize the virus. They provide immunity to the body for months and years.

For your information, let us tell you that after passing through animal or human cells, the virus becomes weak, until it is not mutated. Which enables it to cause disease. Kodagenics, based in Farmingdale, New York, and Serum Institute of India, a Pune-based vaccine manufacturer in India, have changed its genetic code to weaken the coronavirus, so that viral protein production is less efficient.
