Since February this year, every country has given unprecedented support and been working hard for the research and development of the COVID-19 vaccine. In this vaccine research and development "race", the United States and China have always been in the first group, known as the "head" of vaccine research. Everyone is eagerly looking forward to the release of the vaccine, and finally Pfizer and Moderna announced the results of phase III clinical trials in November.One month later, on December 9, the vaccine developed by the China National Pharmaceutical Group Co., Ltd. (Sinopharm) was approved for marketing in the UAE with an effectiveness of 86%.On the same day, Mexico’s Minister of Foreign Affairs, Esselade, stated that the Ministry of Health of the country had signed an agreement to purchase 35 million doses of vaccines produced by CanSino Biologics Inc. from China.Several Chinese vaccines have been declared effective by many countries continuously:
On Dec. 13, the vaccine developed by Sinopharm was approved for marketing in Bahrain;
On Dec. 16, the Brazilian Minister of Health stated that the Chinese vaccine will be put into use locally in February 2021;
On Dec. 24, the Turkish Minister of Health announced the effectiveness of SINOVAC BIOTECH CO.,LTD.’s vaccine. Data analysis of Turkish vaccinated volunteers showed that the effectiveness of the vaccine was 91.25%. No serious side effects were found in the test. China has approved the export of vaccines to Turkey, and the first batch of 3 million doses of vaccines will arrive in Turkey in the near future...
So,what is the difference between Chinese vaccines and American vaccines?
China's vaccines use the first-generation vaccine technology-inactivated vaccines which has been repeatedly verified,such as hepatitis A, influenza and rabies vaccines.But there is a theoretical possibility of an ADE effect.The US vaccine uses the third generation of vaccine technology -mRNA vaccines,which have higher antibody levels and generally do not cause ADE.But the biggest concern is that mRNA vaccine technology is so new that none of the vaccines currently on the market using this technology, so its duration and long-term effects on humans are unclear.Anyway, the effectiveness of these vaccines is good news for the people.
The use of a large number of vaccines can’t be achieved without vaccine storage equipment. Chinese vaccines need to be stored in shaded environment at 2-8°C. Pfizer vaccine and Moderna vaccine need to be stored at -70°C and -20°C respectively,these two vaccines also need to be placed in an environment of 2-8°C before vaccination. According to the different types of vaccines you use, Meling can provide you with 2-8℃ medical/pharmacy refrigerators, -25℃ biomedical freezers or -86℃ ultra-low temperature freezers for your choice.
Safeguarding the health of millions of people by ensuring the safety and effectiveness of vaccines, Meling has appeared countless times in this battle against the pandemic and will continue to contribute to the fight against the COVID-19.
