Live, Attenuated Vaccines

Live, attenuated vaccines are a type of vaccine that use a weakened version of a virus in order to create an immunity to the virus in the vaccinated person. These weakened viruses are not able to cause the disease, however they can still induce an immune response in the body, which then remembers the virus and should be able to fight off the actual virus if it is encountered in the future. This type of vaccine is particularly effective against certain viruses, such as influenza and measles, providing an effective and long-lasting immunity. Not only does this protect the individual from the disease, but it also reduces the spread of the virus in the population, helping to keep everyone safe.
