Vaccines are very important to prevent and control the occurrence and prevalence of infectious diseases. With the continuous improvement of people's health awareness, the market demand for human vaccines is gradually increasing. The production and preparation of vaccines require various consumables, among which cell factories are an indispensable one in large-scale production.

Relevant data show that since the advent of vaccines, immunization has saved 3 million lives around the world every year and prevented 750,000 children from disability. my country has also included some vaccines for human use into the immunization plan, and vaccinated children for free, such as BCG vaccine, hepatitis B vaccine, polio vaccine, DTP vaccine, leprosy vaccine, etc. Due to the indispensability of vaccines in the prevention and treatment of infectious diseases, their market demand cannot be underestimated. my country imports a large number of vaccines for human use. According to the General Administration of Customs, China's imports of vaccines for use in 2017-2019 continued to grow, reaching 10.351 billion yuan in 2019, a year-on-year increase of 89.93%; in the first half of 2020, it reached 7.734 billion yuan, a year-on-year increase of 43.6%. The side shows that the domestic demand for human vaccines in my country is strong.

cell factories

The production process of vaccines includes the establishment of seed banks, cultivation, harvesting, purification, batch filling, packaging, etc. The cell factory is a multi-layer structure of cell culture consumables. Common specifications include 1-layer, 2-layer, 5-layer, 10-layer, With 40 layers, it has the advantages of saving manpower, material resources, space, etc., and it is convenient for proportional expansion, with less pollution, and plays an important role in the large-scale preparation of vaccines.

At present, the cell factory is mainly used in hepatitis A vaccine, chickenpox vaccine, leprosy and mumps vaccine, polio vaccine, hemorrhagic fever with renal syndrome vaccine, hepatitis A vaccine, herpes zoster virus vaccine, rotavirus vaccine, forest encephalitis vaccine, rabies vaccine Preparation of vaccines such as virus, human influenza vaccine and erythropoietin. At present, the new crown virus is raging, residents pay more attention to their own health problems, and the market demand for vaccines continues to rise. It is expected that the market demand for human vaccines in my country will continue to expand in the future, thereby driving the market demand for cell factories.

The FAI climbed 5.9 percent year-on-year in the first 11 months of 2018, quickening from the 5.7-percent growth in Jan-Oct, the National Bureau of Statistics (NBS) said Friday in an online statement.

The key indicator of investment, dubbed a major growth driver, hit the bottom in August and has since started to rebound steadily.

In the face of emerging economic challenges home and abroad, China has stepped up efforts to stabilize investment, in particular rolling out measures to motivate private investors and channel funds into infrastructure.

Friday's data showed private investment, accounting for more than 60 percent of the total FAI, expanded by a brisk 8.7 percent.

NBS spokesperson Mao Shengyong said funds into weak economic links registered rapid increases as investment in environmental protection and agriculture jumped 42 percent and 12.5 percent respectively, much faster than the average.

In breakdown, investment in high-tech and equipment manufacturing remained vigorous with 16.1-percent and 11.6-percent increases respectively in the first 11 months. Infrastructure investment gained 3.7 percent, staying flat. Investment in property development rose 9.7 percent, also unchanged.
