Two covid-19 vaccines developed by Beijing Sinopharm Group Company Limited and Beijing Sinovac Biotech Ltd have been in the list for emergency use by WHO to relief the unfair distribution of vaccines all around the world, especially for low income countries.
According to the statement anounced by WHO on June 1st, the inactivated vaccine developed by Sinovac has passed the procedure of certification lately. Including another inactivated vaccine from Sinopharm, which has been used for emergency use earlier, China provides two vaccines to help to restrain the spread of coronavirus globally.
Based on the clinical trial data from Chile, the efficay rate of virus infection of Sinovac vaccine after 14 days remained 67%, and 85% for successful precaution of severe cases. And it is 84% and 100% for the data of Turkey's experiment accordingly.
The Sinovac vaccine requires simple storage condition in room temperature. Liu Peicheng, a chief inspector of Sinovac company, said that the vaccine can be stored in 25℃ for 42 days; in 37℃ for 21 days. This helps cut down the expense of the storage of vaccine and make the China covid-19 vaccine more competitive among the others.
Experts from WHO said that both vaccines from Sinopharm and Sinovac are safe and effective. Both are applied for people aged over 18. For elders over 60 years old, it is still suggested to be administered. Though there is less clinical trial data for this age group, the two covid-19 vaccines could offer protective effect more or less.
Now the Sinopharm and Sinovac vaccine have been exported to Brazil, Turkey, Indonesia directly. And has provided millions of doses to other 80 countries. More than 300 million people around the world have been inoculated the China covid-19 vaccine already.
In China domestic, over a billion doses of Covid-19 vaccine have been administered up till June 19th. From 900 million doses to 1 billion doses, China took only 5 days, which was the most astounding speed around the world.
Due to the outbreak of Delta variant globally and over 200 confirmed infections in Guangzhou, vaccination in China has been accelerated since early of May.
There were only about 74 million doses have been administered before April nationwide. One month later, the number went up to 1 billion doses. To catch up the goal of herd immunity, the Chinese authorities used every possible way to encourage people to inoculate, such as lucky draw and free gift. It is estimated that over 70% people of China will be vaccinated by the end of 2021.
