Increased transmission capacity, leading to increased disease severity The disease control department confirmed that it was the Delta strain that caused the Nanjing epidemic, and this is not the first time that the Delta mutant strain has invaded our country.

Focus 3: What should I do if I get infected after the vaccine? Still within the scope of protection, it is not necessary for the general population to be vaccinated temporarily This round of the local epidemic has puzzled many people: "Why are they still infected after the vaccine?"
Shao Yiming, a member of the expert group on vaccine research and development of the State Council’s Joint Prevention and Control Mechanism Scientific Research Group, explained: “After being infected after a vaccine, we call it a'breakthrough case'.
State Council According to Shao Yiming, existing studies have shown that vaccines of various technical routes around the world have indeed shown a certain degree of protection against new coronavirus variants, but they are still within the scope of protection of existing vaccines, especially the neutralizing antibodies and protection rates of vaccines.
Based on real-world research carried out in countries with large-scale epidemics overseas, especially the study of more than 10 million people carried out in Chile, the overall protection rate of vaccines of China's Kexing Company protects against critical illness, entry into ICU and death cases.

5 In order to better respond to the epidemic prevention and control, many countries are currently considering the deployment of intensified vaccination injections
.
The first batch of vaccinated people in China has also been more than 6 months old

Is it necessary to inoculate booster shots?
Shao Yiming said: "There is not enough evidence to show that the entire population needs to be vaccinated with the third dose
.
" Preliminary observations indicate that there is no need for booster vaccination for the general population who has completed immunization within one year
.
However, is it necessary for the elderly who have completed immunization for more than 6 to 12 months and have weak immune function and patients with underlying diseases, as well as those who need to go to high-risk areas due to work, and those who are engaged in high-risk occupations in China? The strengthening of the injection and when to carry out the strengthening of the injection are being studied
