Vaccinations 

   Vaccination plays a key role to not only prevent infections among adults, but also for babies to acquire immunity. This is the reason why infants’ immunity naturally diminishes 3 to 6 months after birth.
 There are two types of vaccinations: ones that are legally required by citizens for the prevention of specified diseases on a designated schedule, and ones that are not. 
 Please ask for details at the municipal health care centers in your area.
