Vaccines work by making us produce antibodies to fight disease without actually infecting us with the disease. and thn our immun system will regonise and produce some antibodies against the disease. 

and new born baby have alredy protected against the disease like 
 measlesmumps and rubella becoz antibodies passed in them through mother via placenta .its called passive immunity . and this is lasted up 1 month only
