Is the second injection of COVID-19 more responsive? Does the third injection of COVID-19 not respond? Does it indicate good physique

Is the second dose of COVID-19 vaccine more responsive

depends on the situation. The role of the second dose of COVID-19 vaccine is to ensure that the vaccine can strengthen the immune function of the human body. Because everyone's physique is different, the reaction to the second dose is also different. Some people may have a greater response, while others may have a reduced response. But generally speaking, these adverse reactions are within a safe and acceptable range. After the second dose, it is recommended to observe for 30 minutes in the observation area. If the adverse reactions are significant, it is recommended to report them to the vaccination institution in a timely manner and cooperate with relevant staff to keep records. Because the first shot of COVID-19 vaccine has produced antibodies in the body, and the second shot of inactivated vaccine has been injected, causing the first shot of vaccine to produce antibodies in the body "resistance", so you will feel obvious side effects, but not everyone will have side effects, which has a lot to do with personal constitution.

Is there no normal reaction after COVID-19 vaccination

It is normal that there is no reaction after COVID-19 vaccination. Everyone's physique is different. Some people may experience itching or pain at the vaccination site, and may also experience acid swelling after receiving the COVID-19 vaccine. Some people may experience nausea or headache, and may also experience muscle soreness. Most people also have no response, so it is normal to have no response after receiving the COVID-19 vaccine. After the vaccination of COVID-19 Vaccine Department, the health condition of the body should be closely observed, and if there is any abnormality, you can see a doctor in time. It is normal that there is no response to the COVID-19 vaccine. Everyone's reaction to vaccines is different. Some people have it, some don't. Some people may experience discomfort such as low-grade fever and nausea after vaccination, which is a normal phenomenon, but most people will not have any reactions. No response is also normal. Please don't worry too much. It is recommended to keep warm, avoid the cold, and prevent colds in daily life. It is recommended to rest after vaccination, avoid overexertion, drink plenty of water, have a light diet, and avoid spicy and allergenic foods. Pay attention to the cleanliness of the eye needles and do not scratch them.

The lack of response to the COVID-19 vaccine indicates good health.

It is not true. Whether there are adverse reactions to the COVID-19 vaccine is not a standard to measure good health. Everyone's physique is different. Some people will have adverse reactions after receiving COVID-19 vaccine. Some people have not responded. Adverse reactions do not necessarily indicate poor physical condition. Similarly, without any response, the constitution cannot be said to be good. COVID-19 vaccine can make human body produce antibodies, thus greatly reducing the infection rate of COVID-19. However, as COVID-19 vaccine is a new type of vaccine, it cannot guarantee 100% effectiveness, and there are some adverse reactions after injection. Because the COVID-19 vaccine technology is not yet mature, as long as the adverse reactions are within the normal range, it can be understood as a certain safety.

Is the second dose of COVID-19 vaccine a booster shot?

The second dose of COVID-19 vaccine is not a booster shot. The frequency of vaccination for different vaccines varies, mainly depending on the effect after vaccination. The effectiveness of vaccination should comprehensively consider factors such as antibody levels, antibody persistence, immune memory, and disease prevention effects. Generally speaking, the more times one is vaccinated, the better the effect, as each vaccination has a stimulating effect on the immune system. However, this does not mean that unlimited vaccination can be achieved. After reaching a certain dose, the immune effect will not be enhanced. In phase I and phase II clinical trials, the antibody titer of COVID-19 vaccine was lower than that of the latter. Therefore, it is recommended to use two doses of inactivated vaccine. The two injections of the new coronavirus vaccine are the same, but it takes some time. Usually, the interval between two injections is 3 to 8 weeks. After the first injection, the positive rate of the body is low and insufficient to resist the invasion of the virus. After the second injection, the antibody positivity rate can reach 90%, which has a strong protective effect on the body. During the vaccination process, avoid delaying or missing vaccinations. Once the vaccine is missed, the protective effect in the body will be greatly reduced.
