The New Crown third booster is not not recommended, but is determined on a case-by-case basis for the vaccinated person to be given or not given. The human body will produce antibodies to the New Crown virus after receiving the New Crown vaccine, but over time the antibodies in the human body will become less and less effective, thus requiring a booster shot. However, the third booster shot is not recommended for those who have had allergic reactions and other adverse symptoms from previous vaccinations, and for those who are suffering from an acute exacerbation of the disease, in order to prevent the body from having a serious adverse reaction. Before receiving the third booster injection, the vaccinee should explain his/her situation in detail to the doctor before deciding whether to receive the vaccination, especially for some special groups of people such as women during pregnancy. If you feel unwell after receiving the third booster vaccination, you should consult a doctor immediately to avoid delaying your condition.
