Must the third dose of COVID-19 be vaccinated? I have an appointment with COVID-19, but I didn't go to get the vaccine

Since the emergence of COVID-19, it has spread all over the world, and the number of infected people has increased every day. Although it has been controlled in China, there is still a risk of outbreak if the country is opened to the outside world. So everyone should actively take precautions and vaccinate COVID-19 vaccine as soon as possible. Is it necessary to take COVID-19 vaccine? Let's look down.

vaccine is mainly to prevent disease, but also to prevent severe diseases and death. From the current results, whether in clinical trials or post market observations, it is more effective in preventing severe illness.

In the past, most of the vaccines we used had a protection effect of 90%, while others had protection effects of 80% and 70%. But to make vaccines play a greater role, we need to maintain their high vaccination rate and consolidate this high vaccination rate. Only in this way can diseases be effectively controlled.

Through the orderly vaccination of COVID-19 vaccine, the immune barrier of the population can be established, and the purpose of blocking the epidemic and transmission can be finally achieved. If herd immunity cannot be established, once a source of infection exists, because the vast majority of people do not have immunity, the disease will spread and there is a possibility of transmission.

There are mainly three kinds of domestic COVID-19 vaccines: the first is inactivated vaccine, the second is adenovirus vector vaccine, and the third is recombinant subunit vaccine approved for emergency use. Currently, the first two types are commonly used. Simply put, if there is a need to travel to the epidemic area but there is no time to wait for the second dose, adenovirus vector vaccine is suitable for vaccination. For others, it is more suitable to receive two doses of inactivated vaccine. In fact, the occurrence of adverse reactions is related to the characteristics of vaccines, individuals' special constitutions, and individual differences. In addition, in order to reduce or control risks, for individuals with immunodeficiency, live attenuated vaccines should not be administered, and inactivated vaccines should be used as a substitute.

If you make an appointment through the vaccination service app, please go to the hospital on time to complete the vaccination. The vaccination service application has an interruption appointment mechanism. If you fail to make an appointment three times, it will take one month before you can make an appointment. If you cannot make an appointment on time, please cancel one day in advance.

3. If you make an appointment by phone: You can call the hospital to see if you can change the time or reschedule the appointment.

Because severe allergic reactions occur about 15 minutes after vaccination, as long as you stay at the vaccination site for 30 minutes, in case of relatively serious conditions such as laryngeal edema or anaphylactic shock, the vaccination site can provide timely treatment to avoid other accidents. The overall vaccine is very safe, but in order to prevent these very small probabilities, everyone still needs to follow the requirements and stay at the vaccination site for 30 minutes after vaccination before returning home.
