Even if you have a cold and have been vaccinated, don’t be too nervous, you can observe the performance of the vaccinee, such as vital signs including respiration, pulse, blood pressure, temperature, urination and defecation, mental and sleep status, and dietary status. If it is a mild cold, don’t be too nervous and don’t take any medication. Drink plenty of boiled water and pay attention to keep warm to avoid getting cold, if necessary, you can test the blood routine to see if there is any pathogen infection such as virus or bacteria. If the temperature exceeds 38.5℃, it is still necessary to use antipyretics, such as ibuprofen, acetaminophen, etc. If the cold is not very serious, through proper rest, it can be improved within 1 week, and will not affect the normal vaccination.
