The probability of adverse reactions of vaccines in COVID-19 is lower than the average level of all kinds of vaccines, whether it is general reactions or abnormal reactions.
According to the data released by China Center for Disease Control and Prevention, adverse reactions are mainly divided into general reactions and abnormal reactions.
The general reaction is divided into: 1. High fever (2722 cases /65438+ million doses)
High fever means that the body temperature is greater than or equal to 38.6℃, which is also a general reaction among adverse reactions. Generally speaking, it will be fine in two or three days and will not cause other effects on the body.
Second, redness and swelling (675 cases /65438+ 10,000 doses)
Redness is also a common reaction. Red swelling refers to the state of red swelling or even slight swelling at the inoculation site after vaccination, with a diameter of more than 2.6cm. This has a lot to do with the personal physique of the vaccinator. Red 65438 can disappear in 0 ~ 2 days.
Three, induration (304 cases /65438+ ten thousand doses)
Sclerosis refers to a lump and hardening at the inoculation site of the vaccinator, with a diameter greater than or equal to 2.6cm. Inoculators with this symptom can be relieved within seven days without going to hospital for treatment.
Among the adverse reactions, 26078 cases were general reactions, accounting for 82.96%. General reaction mainly refers to one-off or slight collective reaction, which is related to the characteristics of vaccine.
In addition to these adverse reactions, the vaccinator will also have pain, fatigue, fatigue or loss of appetite at the injection site, and these reactions will improve themselves in about two days.
Abnormal reaction -* * 5356 cases, accounting for 17.04%.
The main abnormal reactions are: 1. Allergic skin rash (3920 cases /65438+ million doses).
2. Vascular edema (107 cases /65438+ million dose)
Three, acute severe allergic reaction (75 cases /65438+ ten thousand doses)
Abnormal reaction means that the function of tissues and organs of the body is damaged when the vaccinator is vaccinated, and the probability of abnormal reaction is extremely low. In addition, there were 188 cases /65438+ 10,000 doses of abnormal reactions, and the occurrence probability was 0.07%/65438+ 10,000 doses.
After an abnormal reaction occurs, the vaccinator needs to go to the hospital for diagnosis and treatment, and also report to the vaccination department so as to make a diagnosis of the reaction.
In COVID-19, the adverse reactions of vaccines have always been a topic of public concern, which is also an important reason why many people have been on the sidelines without vaccination.
In addition to China, other countries are also carrying out vaccination, and the adverse reactions of vaccines are very transparent, because the network information is very developed.
Inoculation contraindication 1. Vaccination is suspended because of fever due to cold, wound infection and other reasons, and the body temperature exceeds 37.3 degrees.
Two, the incubation period and onset of chronic diseases, suspension of vaccination.
If the chronic disease is well controlled and not in the fever period, you can also be vaccinated.
However, many people have adverse reactions after vaccination, all of which are in the incubation period of chronic diseases, so they are not found in time.
In this case, you can go to the hospital for a physical examination in advance, and then vaccinate normally after the examination is no problem.
Three, major surgery or radiotherapy and chemotherapy, suspension of vaccination.
Four, urticaria or itchy skin, suspend vaccination.
Five, the body is in a state of discomfort, such as nausea, vomiting, chest tightness, heart discomfort and so on. Vaccination should be suspended. Wait until the discomfort is relieved, or go to the hospital for examination. There is no problem before vaccination.
Cases that are not vaccine adverse reactions are as follows: 1. Inoculators are in the incubation period of chronic diseases, and some adverse reactions and coupling reactions occur after inoculation.
The second is the adverse reaction caused by the psychological factors of the vaccinators.
Many people are too nervous or afraid when they are vaccinated. At this time, the concentrated vaccine is likely to have some adverse reactions. After emotional stability, adverse reactions will disappear.
Third, there are problems with vaccines, such as the quality of vaccines or the irregular work of vaccinators.
Precautions: When carrying out vaccination, you must truthfully inform the vaccinators of your physical condition and contraindications, so that the incidence of adverse reactions caused by vaccination will be greatly reduced.
Old people over 60 years old or patients with acute and chronic diseases must be examined before vaccination to avoid adverse reactions and adverse effects on the body.
Vaccination is necessary, so in order to protect ourselves and others, we must actively vaccinate, so as to form group immunity.
