Vaccines
Hepatitis A
The CDC recommends the hepatitis A vaccine for all children beginning at age one, as well as for those who have not been previously immunized and are at high risk for contracting the disease.For children 12 months of age or older, the vaccination is given as a shot into the muscle in two doses 6–18 months apart and should be started before the age 24 months. The dosing is slightly different for adults depending on the type of the vaccine. If the vaccine is for hepatitis A only, two doses are given 6–18 months apart depending on the manufacturer. If the vaccine is combined hepatitis A and hepatitis B, up to 4 doses may be required. Hepatitis B
The CDC recommends the routine vaccination of all children under the age of 19 with the hepatitis B vaccine. They also recommend it for those who desire it or are at high risk.Routine vaccination for hepatitis B starts with the first dose administered as  a shot into the muscle before the newborn is discharged from the hospital. An additional two doses should be administered before the child is 18 months.For babies born to a mother with hepatitis B surface antigen positivity, the first dose is unique – in addition to the vaccine, the hepatitis immune globulin should also be administered, both within 12 hours of birth.
Bitlis has hot, dry summers and cold, very snowy winters. Economy
Historically, Bitlis produced wheat, which the British, in 1920, described as being "particularly excellent." However, poor trade routes in the area during the early 20th century meant that the wheat was mainly produced and used by locals. During this time, the British stated that the people of Bitlis were unable to use all of the wheat they produced, and most was "left to rot in the underground storehouses." Notable individuals
