Guangzhou Daily News (All-media reporter Wu Ling correspondent Sui Disease Control) At present, 11 districts in Guangzhou have started the vaccination of the new crown virus vaccine "reinforced needle". Yesterday, the Municipal Center for Disease Control and Prevention carried out scientific popularization of the target objects of enhanced immunization, the selection of reinforcing needles, and the precautions for vaccination of reinforcing needles.
The Municipal Center for Disease Control and Prevention said that vaccination against the new crown virus is an effective measure to prevent new crown pneumonia, and it is also the responsibility and obligation of every citizen, calling on those who meet the conditions but have not yet received the first injection to be vaccinated as soon as possible, and those who have not completed the whole process of vaccination should complete the whole process of vaccination as soon as possible, and complete the strengthening of immunization as soon as possible in line with the conditions for strengthening immunization.
1. What is a reinforcement needle?
Booster needles are also called booster immunity. Because some of the immunoprotective effects produced after vaccination have a certain period of time, after completing the basic immunization after a certain period of time, the body's immunity gradually weakens or disappears, in order to continue to maintain a solid immunity of the body, it is necessary to re-vaccinate in a timely manner according to the immune characteristics of different vaccines, which is to strengthen immunity.
2. What is the target of this covid-19 vaccine to boost immunization?
The new crown virus vaccine will strengthen immunization, giving priority to key personnel such as high-risk infected groups and key positions to ensure the basic operation of society, and will also expand the scope of target groups accordingly in combination with the needs of epidemic prevention and control, such as customs, border inspection, aviation, isolation points, designated medical institutions and other staff. People with relatively low immune function, people over 60 years old, due to the needs of work, study and communication, people who want to go to high-risk areas or countries of overseas epidemics, and people who need to be in need for other reasons can strengthen immunization.
The conditions to be met are 18 years old and older people who have been vaccinated with Beijing Biologics, Beijing Kexing Zhongwei and Wuhan Biological New Coronavirus Inactivated Vaccine for 2 doses (including mixed vaccination) for 180 days, and 18 years old and above who have been vaccinated with The Cansino adenovirus vector vaccine for 180 days.
3. How to choose a vaccine that enhances the use of immunization?
People who have completed two doses of inactivated vaccines from the same company have in principle used the original company vaccine for one dose of booster immunization; people who have completed two doses of inactivated vaccines from different companies have in principle given priority to using vaccines from the same company as the second dose for enhanced immunization, and if the vaccine of the second company cannot continue to be supplied, the vaccine of the same company as the first dose can be used for enhanced immunization; the population vaccinated with the cansino adenovirus vector continues to use the cansino adenovirus vector vaccine for enhanced immunization.
4. Is it safe to boost immunization?
The experts of the National Vaccine Research and Development Special Class have conducted full research and demonstration, and after completing the full immunization of the new coronavirus vaccine for 6 months (180 days), 1 dose of reinforcing antibodies has been given, and the neutralizing antibodies in the recipients have increased rapidly; after 2 weeks of enhanced immunization, the level of neutralizing antibodies can be increased several times or even dozens of times compared with before vaccination; not only that, the antibody spectrum of the new coronavirus vaccine reinforcing needles is also wider, which can produce better protective effects on the mutant strains. The incidence of adverse reactions after booster immunization was no different from the first and second doses.
5. Where to get the third dose of the vaccine?
At present, all COVID-19 vaccination clinics can basically receive a third dose of COVID-19 vaccine, specifically consult the local vaccination unit.
6. What are the precautions?
When vaccinating, it is necessary to carry ID cards, passports and other relevant documents, and according to local prevention and control requirements, do a good job of personal protection, cooperate with on-site vaccination staff to inquire; previous diseases and whether to take drugs in the near future should inform the doctor.
After vaccination, stay for 30 minutes according to the regulations; keep the local skin clean and avoid scratching the vaccination site with your hands; if there is a suspected adverse reaction, please report to the vaccination unit and seek medical treatment in time if necessary.
