The Rubella Vaccine is designed to protect against rubella, a contagious viral infection that can cause serious complications, especially in pregnant women. The vaccine is typically given as part of the MMR vaccine, which also protects against measles and mumps. It is usually administered in childhood, providing long-lasting immunity. Vaccination against rubella is crucial for public health, as it helps prevent outbreaks and protects vulnerable populations. The vaccine is safe and effective, with most individuals experiencing only mild side effects, such as soreness at the injection site. Widespread vaccination has significantly reduced the incidence of rubella worldwide.
