Vaccine Live (v.vivum) is a live, weakened strain of the virus that is used to create immunity against various diseases, such as influenza, measles, rubella and others.
A live vaccine is a weakened version of the real virus that cannot cause disease but can stimulate the immune system to fight it. This means that when the vaccine is introduced into the body, it will react to the presence of the virus and produce antibodies that will protect against the disease in the future.
The Live vaccine was developed in the 1920s and has since been widely used throughout the world to prevent many viral infections. It has a number of advantages over other vaccination methods, such as no need for storage and transportation, and no side effects.
However, the live vaccine also has its disadvantages. First, it may cause some side effects such as fever, headache and fatigue. Secondly, it is not always 100% effective, especially when used against new strains of the virus.
Despite these shortcomings, the live vaccine remains one of the most effective ways to combat viral infections and continues to be used in many countries around the world.
