Sabinâs live-virus, oral polio vaccine (administered in drops or on a sugar cube) soon replaced Salkâs killed-virus, injectable vaccine in many parts of the world.
Every time another dose of the vaccine is given, your baby's immune response increases. The vaccine is injected into your baby's thigh. The 5-in-1 vaccine works well. It produces very good immunity to diphtheria, tetanus, whooping cough, Hib and polio infections. The 5-in-1 vaccine is very safe. It's inactivated, which means it doesn't contain any live organisms, so there is no risk of your baby getting the diseases it protects against.
