Getting a third booster shot generally refers to the third booster shot of the Neocoronavirus vaccine. Contraindications include uncontrolled neurological disorders, a history of vaccine allergy, pregnancy, and fever. Currently, on top of the two doses of the Neocoronavirus vaccine, a third shot is recommended to increase the Neocoronavirus antibodies in the body and strengthen the ability to prevent the Neocoronavirus, also known as the third booster shot. According to the Neocoronavirus Vaccine Precautions recommendations, vaccination is not recommended for patients with uncontrolled epilepsy and other serious neurological disorders (e.g., demyelinating diseases, Guillain-Barré syndrome, etc.). For those who have had severe allergic reactions (e.g., acute anaphylaxis, respiratory distress, etc.) during the first two vaccinations, they should not be vaccinated. Those who are allergic to vaccine components and excipients (sodium chloride, sodium dihydrogen phosphate, etc.) should not be vaccinated. People who are suffering from fever or acute illness, or acute exacerbation of chronic diseases (acute exacerbation of chronic obstructive pulmonary disease), and uncontrolled severe chronic diseases (systemic lupus erythematosus, rheumatoid arthritis, etc.) cannot be vaccinated. Women during pregnancy cannot be vaccinated, and those with thrombocytopenia or bleeding disorders (hemophilia) cannot be vaccinated. For the third booster shot of the new crown vaccine, there are certain contraindications, so it is recommended to seek medical attention and consult a specialized doctor in detail.
