However, they are turning their interest towards the United States and Europe; amid concerns regarding the efficacy of China-made Covid vaccines. Several reports suggest that Chinese Covid vaccines are not that effective against the Delta variant as the country witnessed a recent outbreak of Coronavirus cases in July this year. The export of Chinese vaccines dropped 21 percent in August to $1.96 billion from $2.48 billion in July this year.

Suggestions from the Experts

Experts from all parts of the world suggest that people opted for China’s COVID-19 vaccines; because they were all that was available at that point in time. Basically, people relied on what they got. Nicholas Thomas, associate professor at the City University of Hong Kong; said that people are now educated regarding Covid vaccines. Moreover, they know the differences between different vaccines and are aware of opting for the right one. Besides that, they have also realized that all vaccines are not equal, and each one offers a different level of protection.

Chinese Covid Vaccine’s Efficacy


The efficacy of China’s COVID-19 vaccines ranges between 50 percent to 80 percent in clinical trials. However, they are comparatively less potent than mRNA vaccines are said to offer less protection against the deadly Delta variant. Thailand was one of the countries to purchase China’s Sinovac vaccine in bulk; as they were left with no other option. Amid the rising COVID-19 cases in Thailand, the country had to confront a new set of challenges even after inoculating its citizens. Henceforth, Thailand became the first country to inoculate its citizens with a Pfizer jab even to those who had received the Sinovac vaccine. Although Pfizer’s vaccine is also not mRNA-based, it offers better protection than the Sinovac COVID-19 vaccine.

On the other hand, India has also resumed its export of AstraZeneca COVID-19 vaccines. Besides that, Chinese vaccines are not authorized in some countries such as Singapore.
