Rubella is a viral infection with mild clinical symptoms and a good prognosis that is easily overlooked. However, rubella is one of the leading causes of congenital defects. Developed countries have long considered rubella prevention as an important measure for eugenics, using vaccination and early pregnancy monitoring to reduce the occurrence of rubella. You are advised to get vaccinated. Antibodies are produced after vaccination to protect the embryo, but you should not get pregnant until at least three months after the vaccination, remember! Remember not to eat eggs and other things you are usually allergic to after vaccination. Rubella vaccine side effects are inherent reactions caused by the characteristics of the vaccine itself, most of which are mild or transient and do not cause irreversible tissue or organ damage or dysfunction.
