What does COVID-19 Vaccine vero Cell Mean

Inactivated novel coronavirus pneumonia vaccine is a vaccine that can be used to prevent COVID-19, that is, it can prevent diseases caused by novel coronavirus infection.

Vero cells are a type of heteroploid cell, which refers to African green monkey kidney cells. They are derived from monkey kidney cell culture and are commonly used cell lines like the famous Hela cell line and canine kidney cell line.

Vero cells can be used to detect E. coli toxins, serve as cell hosts for cultivating viruses, and act as host cells for eukaryotic parasites. The reason for choosing Vero cells to produce viruses is because they have the ability to be easily cultured, stably transmitted, and can divide infinitely. Therefore, Vero cells are used in the production of many vaccines.

The principle of vero cell of COVID-19 vaccine

The first step in the production of COVID-19 inactivated vaccine is to reproduce a large number of COVID-19. The isolated COVID-19 strains will be sent to the vaccine production workshop for reproduction, and vero cells are used as the basis for the mass propagation of viruses.

The principle of vero cell of COVID-19 vaccine is actually to prepare the vaccine through a series of purification techniques after inactivation of the live virus after cultivation and amplification. The main characteristics of inactivation are strong immune response, good safety and stability, making it convenient for transportation. It adopts a two shot immunization program, with an interval of more than 28 days and no less than 56 days between the two shots.
