1, Q: Why do we need to strengthen immunization with COVID-19 vaccine?
A: The epidemic situation in COVID-19 is still prevalent, with many local cases, and the situation of epidemic prevention and control is grim. Vaccination with COVID-19 vaccine can reduce the risk of serious illness and death caused by mutant strains in COVID-19, including Omicron. However, with the passage of time after vaccination, the protective effect of vaccine may be weakened, and it is necessary to strengthen immunity to make the body produce higher antibody levels. Studies have shown that strengthening immunization after six months of full vaccination of COVID-19 vaccine can rapidly increase neutralizing antibodies in vivo and effectively resist COVID-19 mutant. Therefore, it is necessary for school-age people to strengthen immunization in time.
2. Q: Who is the target population for the supplementary vaccination in COVID-19?
Answer: People aged 18 or above have completed two doses of inactivated COVID-19 vaccine or 1 dose of adenovirus vector vaccine for six months.
3. I heard that you can choose sequential immunization now. What is sequential immunization?
A: Strengthening immunization can be divided into homologous strengthening and heterologous strengthening. The former refers to vaccination with the same technical route as basic immunization, and the latter refers to an vaccination strategy adopted by strengthening immunization and basic immunization with different technical routes in order to obtain better preventive effect or further reduce the risk of serious adverse reactions.
4. What are the COVID-19 vaccines that are suitable for strengthening immunization in Tianjin?
A: At this stage, the target population can choose the adenovirus vector vaccine of Tianjin Kangxinuo Company or the recombinant protein vaccine of Anhui Zhifeilong Kyle Company for 1 dose sequential booster immunization. At the same time, you can also choose the original technical route vaccine for homologous booster immunization.
5. Q: Is it necessary for the elderly to be vaccinated?
A: The elderly belong to the key population who have completed the intensive immunization. Vaccination with COVID-19 vaccine is an effective means to reduce the risk of severe illness and death. According to the analysis of epidemic data in China, the risk of severe illness among the elderly who have been vaccinated with COVID-19 vaccine is obviously lower than that of the elderly who have not been vaccinated. It is necessary for the elderly to be vaccinated with COVID-19 vaccine!
6. Q: Is it safe to vaccinate the elderly?
A: As of June 9 this year 165438+, more than 3.44 billion doses of COVID-19 vaccine have been vaccinated in China, and more than 33.36 million doses have been vaccinated in Tianjin, including 6.72 million doses for the elderly aged 60 and over, with the maximum vaccination age 109. The monitoring data show that the COVID-19 vaccine used in China is very safe, and the probability of serious adverse reactions after vaccination is very low, so the elderly can be safely vaccinated.
7. Q: What is the effect of COVID-19 vaccine booster?
A: Studies have shown that neutralizing antibodies have increased rapidly among people who have completed immunization. After two weeks of booster immunization, the neutralizing antibody level can be increased several times or even dozens of times compared with that before vaccination, and the antibody level formed after booster immunization has also decreased after half a year, but it is still higher than the peak value after the whole vaccination, which will also have a good protection effect on mutants.
8. Q: Some elderly people don't go out often. Do they need to be vaccinated?
A: No matter how small the activity is, the vaccination should be completed as soon as possible. Old people often don't go out, which doesn't mean there is no risk of infection. They can only say that the risk of infection will be smaller than that of people with a wide range of activities and frequent activities.
At present, the epidemic situation in China is grim, and local epidemics appear in many places. The proportion of asymptomatic infected people is mostly, and the risk of infection is everywhere. Moreover, with the coming of autumn and winter, the temperature drops and the virus becomes more active, and people, environment and family members around the elderly may bring the risk of infection. Once infected, it is easy to cause serious consequences to the elderly.
9. Q: My elderly people have basic diseases such as diabetes and hypertension. I'm not sure if I can get a vaccine
A: You can prepare the relevant medical records in advance, tell the vaccination doctor the health status truthfully, and let the professionals at the inoculation point or the designated hospital make a judgment.
Moreover, in order to ensure COVID-19 vaccination for the elderly, Tianjin has set up a mobile vaccination service team for the elderly, providing home vaccination services for the elderly with mobility difficulties, and contacting community workers if necessary.
10, Q: Can I still take therapeutic drugs every day after vaccination?
A: People with basic diseases in the past can continue to take daily treatment drugs, such as antihypertensive drugs and hypoglycemic drugs.
1 1. Q: My old man is afraid of injections. I heard that there is an inhalation vaccine now. Can he get an inhalation vaccine?
A: At present, the recombinant COVID-19 vaccine for inhalation is only used to strengthen immunity. 18 years old and above, who have been vaccinated with inactivated vaccine produced by Sinopharm China Biotechnology Co., Ltd. and Beijing Kexing Zhongwei Biotechnology Co., Ltd. or intramuscular recombinant COVID-19 vaccine produced by Kangxinuo Biotechnology Co., Ltd. for 6 months, can choose this vaccine for 1 dose booster immunization.
