The first single-injection COVID-19 vaccine in China is here, and it can be stored at 2-8 ℃!

2021 Nian 2 Yue 25 days, a team led by Chen Wei and Kang Xinuo biological AG developed adenoviral vector vaccine Ad5-nCoV approved listing. It is reported that the vaccine is currently the first vaccine approved by the country that can adopt a single-dose vaccination procedure; good protection effect can be obtained 14 days after single-dose vaccination , and it can be transported and stored at 2~8 ℃ . It is expected that single-dose vaccination can be used for new crowns. The annual production capacity of vaccines may reach 500 million.

What are the benefits of the single-dose vaccine being approved for marketing? First of all, the procedure for single-shot vaccination is simple, only one shot is needed. Compared with multiple shots , more people can be vaccinated in the same time period, and as many people as possible can be protected in the shortest time. Ad5-nCoV can achieve rapid mass vaccination of the population, enhance people's preventive ability, form a disease control method that focuses on prevention and control, and prevents a new round of outbreaks . In the latest CDC Weekly Report, Gao Fu, director of the Chinese Center for Disease Control and Prevention, said that there are many uncertainties in 2021 , one of which is that the new coronary pneumonia may become a long-term infectious disease globally or in local areas. Therefore, in addition to exercising, a balanced diet to improve resistance, and personal protection, the public is also a good preventive option by injecting the new crown vaccine. But getting vaccinated against the new crown does not mean that you will no longer be infected with the new crown, because the virus will mutate. Now several variants of the new crown virus have been found around the world, so even if we are vaccinated with the new crown vaccine, we must do our daily personal protection work. .

In addition, it is understood that another significant advantage of Cansino vaccine is that it only needs to be stored at 2 to 8 degrees Celsius, which is suitable for long-term transportation and storage. For example, we are familiar with Pfizer vaccine , it needs at minus 70 storage environment ℃ in and transport, even at such ultra-low temperature environment, the vaccine is only 6 months after the expiration date, and into ordinary refrigerator, its shelf life is only There are 5 days. Vaccines, biological products, are very sensitive to temperature, and require cold chain transportation and storage in cold storage throughout the entire process. Many vaccines are in the process of transportation. Due to temperature changes, too high or too low temperatures cause the vaccine to fail, or the cold chain fails to meet the vaccine transportation requirements, resulting in a shorter vaccine shelf life, and so on.

Therefore, the establishment of a professional and supporting vaccine cold chain logistics and transportation system must be put on the agenda. In addition, temperature changes need to be monitored during vaccine transportation to ensure vaccine activity. This requires the help of an instrument, a temperature and humidity recorder, which is used for the mobility of cold chain vehicles. We need to use a wireless temperature and humidity recorder to be more convenient. The HK-J8A102/HK-J8A103 multifunctional digital thermometer and hygrometer is an industrial-grade, high-precision temperature and relative humidity measuring instrument. The instrument is powered by a 9V battery and uses an external high-precision probe. It has the functions of measuring humidity, temperature, dew point temperature, wet bulb temperature, data recording, and data retention to freeze the current readings. It reserves the Internet of Things ioT function. The USB interface is convenient for exporting data. Easily respond to the demand for accurate temperature and humidity measurement in various occasions.

If you need a smaller wireless temperature and humidity recorder, you can choose the HK-J9A100 series temperature and humidity data logger. It is compact and convenient, convenient to carry, and has a small use space. It uses a high-precision sensor to measure temperature and humidity. Automatic storage of data at set time intervals, and equipped with intelligent data analysis and management software, to provide users with long-term, professional temperature and humidity measurement, recording, alarm, analysis, etc., to meet customers' different application requirements for temperature and humidity sensitive occasions .

Under the severe global epidemic situation, we must not only pay attention to the research and development of the new crown vaccine, but also pay attention to other aspects of the Covid-19 vaccine , such as cold chain transportation, storage environment and so on. The arrival of 2021 requires everyone to work together to defeat the new crown epidemic. As a member of Chinese enterprises, Hengge will also provide its own strength for the development of Covid-19 vaccine cold chain transportation!
