Is it necessary to get a booster vaccine?

Is it necessary to get a booster vaccine? Clinical data show that no vaccine can 100% prevent infection, but in general, all kinds of mutant strains are still within the controllable range of existing vaccines. The existing vaccines still have good preventive and protective effects, which can reduce the risk of virus transmission in people, reduce the transmission power of infected people, and effectively reduce the incidence and mortality of severe illness after infection.

Is it necessary to get a booster vaccine? 1 With the increase of Delta virus breakthrough vaccine infection cases, the voice of vaccine booster in COVID-19 is getting louder and louder. Does COVID-19 Vaccine Need to be Boosted? Ruan, deputy director of the Jinan Municipal Health and Health Commission and director of the Municipal Center for Disease Control and Prevention, said: "According to a lot of research, it is not necessary to strengthen the vaccination of COVID-19 vaccine in the short term, but in the future, with more and more people vaccinated, including the extension of our vaccination time, whether it is necessary to strengthen it, this also needs a lot of crowd experiments and research to prove it."

Ruan said that when it is necessary to strengthen, the relevant departments will arrange for the public to strengthen vaccination in time according to relevant requirements, so you don't have to worry.

In addition, regarding the public's question about whether the COVID-19 vaccine is effective against the Delta strain, Ruan replied: "Now the COVID-19 vaccine is still effective against Delta, especially to prevent severe illness and death." Therefore, she reminded the public to complete the whole process of immunization and vaccinate in time.

Preliminary observation shows that it is not necessary for the general population who have completed immunization within one year to carry out intensive injection for the time being.

However, for the elderly and patients with basic diseases who have completed immunization for more than 6- 12 months, as well as those who have to work in high-risk areas due to work needs, and those who are engaged in high-exposure occupations in China, whether and when to carry out booster injections are under study.

Is it necessary to get a booster shot? Is COVID-19 Vaccine Effective for Mutants?

Clinical data show that no vaccine can 100% prevent infection, but in general, various variants are still within the controllable range of existing vaccines.

Based on the research carried out by overseas countries with large-scale epidemic, such as Chile110 million people, the protection rate of Kexing company vaccine in China is over 65% for all symptoms and mild diseases, and the protection rates for severe cases, ICU admissions and deaths are 87.5%, 90.3% and 86.3% respectively.

This fully shows that the vaccine in China can effectively reduce the hospitalization rate, severe illness rate and mortality rate.

At present, the epidemic prevention and control measures are still effective for Delta variants, and it is recommended that the public complete vaccination as soon as possible.

Relevant scientific research and epidemic prevention and control practice show that Delta mutation has not caused subversive changes in COVID-19's biological characteristics, and the source of infection and transmission route are basically clear. The existing epidemic prevention and control measures are still effective for Delta mutant.

The existing vaccines still have good preventive and protective effects, which can reduce the risk of virus transmission in people, reduce the transmission power of infected people, and effectively reduce the incidence and mortality of severe illness after infection.

Some time ago, China successfully blocked the local epidemic spread of Delta mutant in several densely populated and mobile cities in Guangdong Province for the first time, which proved that measures such as vaccination, wearing masks, washing hands frequently, keeping social distance and avoiding crowd gathering were effective. According to the requirements of Technical Guidelines for Vaccination in COVID-19 issued by the state, it is not recommended to strengthen immunization at this stage. The inactivated vaccine in COVID-19 was completed twice according to the immunization procedure, and it was not strengthened.

After vaccination, on the one hand, most people can gain immunity; On the other hand, through the orderly inoculation of COVID-19 vaccine, an immune barrier can be gradually established in the population, and the widespread spread and epidemic of COVID-19 can be blocked. Therefore, vaccination is very necessary.

The general public and friends should correctly understand the necessity and importance of vaccination, do not be bystanders and improper outsiders, and actively participate in vaccination in COVID-19, so as to "take the lead and set an example". Need to remind everyone that COVID-19 vaccine must be vaccinated in the whole process to have a protective effect. Therefore, those who have received the first dose of vaccine but not the second dose should complete the second dose of vaccine as soon as possible.
