If the vaccinated person has a sore throat without fever and the pain is mild and not accompanied by symptoms such as redness, swelling of the throat, weakness, headache and nasal congestion, the vaccination can be given normally. However, if the sore throat is caused by acute upper respiratory tract diseases such as cold, acute mumps or tonsillitis, the vaccination is not recommended even if there is no fever. This is because most of these diseases are caused by bacterial or viral infections, and most of the New Crown vaccines are also inactivated viruses. Both infection and vaccination require the participation of the human immune system, so giving the New Crown vaccine at this time may increase the burden on the immune system, which is not conducive to the recovery of the disease, and may also affect the effect of the New Crown vaccine, and may even aggravate the discomfort symptoms of the disease and induce adverse reactions to the vaccine. Moreover, if symptoms such as fever, headache, nausea and vomiting occur, it is not easy to determine whether they are caused by the disease or by adverse reactions to the vaccine, which may affect the doctor’s diagnosis. If the vaccinated person only has a simple sore throat, it may be caused by a very mild infection or fire, which usually has no effect and does not affect the effect of the vaccine and can be vaccinated normally. However, some people may have a sore throat as a precursor to a cold or fever. If the sore throat tends to get worse, it is recommended to observe it for a period of time before deciding whether or not to proceed with the vaccination. Since there are some precautions inherent in the vaccination of the new crown vaccine, it is recommended that vaccinators consult with the relevant medical personnel before vaccination to explain the specific situation and make it clear that the vaccination can be administered before proceeding, and that they need to observe the vaccination site for half an hour after vaccination to prevent uncomfortable symptoms. A small number of inoculated patients may experience slight sore throat, redness and swelling, slight cough, or uncomfortable symptoms such as fever, weakness and muscle aches after vaccination, which are normal and usually disappear after 2-3 days. No special treatment or control is needed. If the symptoms do not subside for a long time or even show signs of aggravation, go to the vaccination site and take further treatment measures in a timely manner.
