Men undergoing IVF can be vaccinated with the New Crown vaccine, while women should consider whether or not to be vaccinated, depending on the stage of IVF. The vaccine is not recommended for women during pregnancy, but if they are preparing for pregnancy, they can receive the vaccine and do not need to postpone their pregnancy plans because of the vaccination. Therefore, for men during IVF, if there are no other contraindications to vaccination, they can receive the New Crown vaccine as normal. For women who are preparing for ovulation in IVF, which is equivalent to the period of preparation for pregnancy, they can have the New Crown vaccine according to their wishes; if they are in the post-embryo transfer stage, which is equivalent to the period of pregnancy, it is recommended that the vaccination be postponed until after the delivery of the baby. Whether or not you can be vaccinated during IVF, it is important to be protected. Women during IVF can discuss with their doctor before deciding whether or not to get vaccinated.
