Is Vaccine Covid-19 Safe ？

The new coronavirus vaccines currently at the forefront of research and development can be summarized into two categories .

The first category is new vaccines that have not been approved for similar vaccines before, mainly referring to nucleic acid vaccines .

The second category is the traditional type of vaccine that has been widely used before, the fire extinguishing vaccine.

Since the fire extinguishing vaccine meets the conditions of 'safe, fast, effective, and mass production ', it seemed that relatively more research has been conducted on it.

E.g. factories with an annual capacity of 300 million doses have also appeared in China .

The so-called inactivated vaccine is simply to isolate the virus strain first, just like selecting a 'seed ', and then reproduce and cultivate it, such as magnification several hundred times, several hundred times, etc.

These live viruses are then killed to make them lose their infectivity and replication ability, but at the same time retain their part of the function of stimulating the body's immune response; finally, they are purified into vaccines. It is reported that based on the combination of animal experiments, phased research results, and previous similar technology platform vaccines, it is highly likely that the durability and protective effect of vaccine immunity will be maintained for more than 1 to 3 years, and it is more likely to be effective against known mutant viruses. There is no problem.

After the vaccine is marketed, the general population can be injected. Under the current state of emergency use, it is recommended to postpone vaccination for pregnant and lactating women.

At present, there are more than 100 new coronavirus vaccine projects in the world at the same time.
