is generally normal.

COVID-19 vaccine is an inactivated vaccine. Like other vaccines, it may have adverse reactions. After COVID-19 vaccine is inoculated, headache occurs the next day, which may be normal.

Adverse reactions to vaccines may generally include symptoms such as fever, fatigue, nausea, headache, muscle pain, etc., but vaccination may cause adverse reactions. There is no problem with the quality and safety of the vaccine itself. The vaccine is composed of pathogenic microorganisms, and its specific properties may cause hypersensitivity reactions.

Temperature can be detected first and observed for 2-3 days. Medication is not recommended temporarily.

To sum up, it is normal for certain adverse reactions to occur after COVID-19 vaccine inoculation. Very few people may have fever, weakness, nausea, headache, muscle pain, etc. due to personal differences at the vaccination site, such as acerbity, redness, swelling, pain, itching, etc.

Tips: If the situation does not ease after COVID-19 vaccine inoculation, attention should be paid at this time. It is recommended to go to the hospital and use drugs under the guidance of the doctor. Do not use drugs blindly.

How long will the headache get better after the COVID-19 vaccine

Usually, it can recover within 2-3 days. At present, no serious adverse reactions related to vaccines have been detected. However, based on scientific and rigorous evidence, like other vaccines, administering a new inactivated coronavirus vaccine may cause common general reactions, such as soreness, swelling, pain, itching, and a very small number of people may experience fever, weakness, nausea, headache, muscle soreness, etc. due to personal differences. However, if there is no improvement after 2-3 days, it is necessary to pay attention to whether it is due to other reasons. It is recommended to go to the hospital and receive treatment under the guidance of a doctor.

How often the side effects occur after the COVID-19 vaccine is administered

Generally, there will be reactions within 30 minutes after the vaccination.

Not all people vaccinated with COVID-19 vaccine will have adverse reactions, but a few people have adverse reactions to varying degrees, but most of them are common adverse reactions such as fever, weakness, nausea, headache, etc.

Generally, within 30 minutes after vaccination, it is possible to determine whether adverse reactions have occurred. Therefore, after vaccination, the recipient must observe on-site for 30 minutes before leaving. However, due to differences in individual immunity, there may be adverse reactions 1-2 days after returning home. At this point, it is necessary to immediately report to the staff at the vaccination site and seek medical attention if necessary.
