Rubella vaccine refers to the live attenuated rubella vaccine and is not a mandatory vaccination before pregnancy. It is important to note that once this vaccine is administered, contraception is required for 3 months. The live attenuated rubella vaccine is intended for rubella-susceptible individuals over the age of 8 months for the prevention of rubella. Before pregnancy, the live attenuated rubella vaccine is not a mandatory vaccine, and women of childbearing age who have childbearing requirements may choose to receive the vaccine according to their own needs. It is worth noting that women of childbearing age should use contraception for at least 3 months after receiving the live attenuated rubella vaccine so that the vaccine will not affect the quality of fertilized eggs. Some people may have adverse reactions such as transient fever and mild rash after receiving the live attenuated rubella vaccine, which usually do not require special treatment and can be relieved on their own. For those who are suffering from serious diseases, in the period of fever, pregnant women and those who are allergic to the efficacy of the vaccine, it is contraindicated to receive the live attenuated rubella vaccine. It is recommended that those who need to receive the live attenuated rubella vaccine should go to a regular hospital for vaccination, and those who need to have children should use contraception for 3 months before starting to prepare for pregnancy. Avoid vaccination with live attenuated rubella vaccine for 1 month before and after the use of other live vaccines, but can be vaccinated with live measles and mumps vaccines at the same time.
