The technical guidelines for vaccination against Neocrown pneumonia suggest that simultaneous vaccination with other vaccines is not recommended for the time being. Therefore, tetanus shots should generally not be given at the same time as Neocrown vaccine, and after tetanus shots, the Neocrown vaccine can be given at an interval of more than 14 days to avoid causing adverse reactions or affecting the effectiveness of the vaccine. Because there are multiple doses of New Crown vaccine, the following two cases are considered. First, if you did not receive the first or second dose of the New Crown vaccine before the tetanus shot, and after receiving the tetanus shot, it is recommended that you can postpone the New Crown vaccine for 14 days since the New Crown vaccine is not a vaccine that requires emergency vaccination. This is to avoid simultaneous administration of the two vaccines, which may cause adverse reactions or affect the vaccine’s ability to produce a response in the body. Secondly, if you have already received the New Crown vaccine before the tetanus shot, you need to continue with the second or third dose of the New Crown vaccine. In this case, it is recommended to consult a professional doctor to decide whether the New Crown vaccine can be administered after the tetanus shot based on the patient’s specific situation, the vaccination status, and the urgency of the vaccine. It is also important to note that vaccination is not recommended or should be withheld for those who are allergic to the components of the New Crown vaccine, those with a previous history of allergy to the vaccine, those with fever, those with acute illness, those in the acute phase of chronic illness, those with uncontrolled epilepsy or those with severe neurological disorders.
