Recently, the epidemic has rebounded and many areas have become medium to high risk areas.

In this outbreak, the delta strain has become the main mutant strain currently spreading. So, is the domestic vaccine still effective against the delta strain? Is the new crown nucleic acid rapid test still detectable?

Zhong Nanshan, an academician of the Chinese Academy of Engineering, clearly answered when attending a summit event in Guangzhou: "It is effective and very safe."

China's epidemic prevention and control practices show that existing epidemic prevention and control measures are still effective against the Delta variant strain, and that existing vaccines still provide good prevention and protection, reducing the risk of transmission of the virus in the population and also reducing the transmission power of infected individuals. However, no vaccine provides 100% protection, and there is still a risk of infection with the virus after vaccination. However, studies have shown that the vaccine provides 100% protection against severe disease, and 76.9%, 67.2%, and 63.2% protection against moderate, mild, and asymptomatic disease, respectively. The incidence of severe disease and morbidity and mortality rates were reduced in cases of viral infection after vaccination.

The current rapid nucleic acid test for neocoronavirus also remains the gold standard for detection of neocoronavirus!

In addition, Academician Zhong Nanshan pointed out that China needs a vaccination rate of 83.3% to achieve herd immunity. For this reason, he specifically urged everyone to pay attention to vaccination.

What is herd immunity? And what is natural immunity?

Herd immunity refers to the resistance of the population to infection. If 70 to 80 percent of the population is resistant to infection, there will be no large-scale epidemic outbreaks.

Natural immunity refers to various forms of immune function that function actively at the time of infection and do not change with a previous pathogen and are characterized by rapid response, broad specificity, and limited efficiency. It can be understood as an innately acquired immunity that does not rely on any means.

From the beginning of the epidemic all kinds of things can be seen, natural immunity is difficult to achieve. Academician Zhong Nanshan even made three no comments on natural immunity: "Unrealistic, unscientific and inhumane." This shows that the initiative of vaccination is essential and can not be delayed.

At present, although the number of vaccinations in China is large, but due to the large population base, it is still far from reaching the requirements of herd immunity. The epidemic has spread globally, and mass vaccination to achieve herd immunity will take 2 to 3 years of global collaboration.

In the absence of global herd immunity, rapid nucleic acid testing of new coronas is still necessary for epidemic prevention and control. In the face of rapid transmission, short incubation period, and high infection rate of Delta virus, it will be very difficult to prevent and control the epidemic if we do not adopt a full coverage approach for rapid nucleic acid testing.

To achieve full coverage of the new crown nucleic acid rapid detection, efficient and accurate new crown nucleic acid rapid detection system is indispensable. Now the domestic mainstream use of the new crown nucleic acid rapid test program, the fastest half-hour nucleic acid test results, can effectively enhance the efficiency of the new crown nucleic acid rapid test. It can be used in fever clinics, airports and ports, etc. It is suitable for all scenarios that require New Crown Nucleic Acid Rapid Test results, providing convenience for people who urgently need nucleic acid results and helping to achieve full coverage of nucleic acid testing.
