There is no evidence of specific effects on the thyroid gland associated with the Neocoronazole vaccine. According to the clinical experience of the current vaccination, the vaccine does not usually cause thyroid-related diseases. However, if some people develop thyroid-related illnesses after receiving the vaccine, they should be reported to the appropriate authorities for analysis and determination of whether there is a correlation by professional doctors. Generally, there may be adverse reactions associated with the New Crown vaccine, such as dizziness, fever, muscle pain, and allergic reactions, such as rashes and itching. The vaccine acts on the immune system and does not affect the thyroid gland. If adverse reactions occur, it is recommended to seek further treatment in hospital.
