Other immunisations are available but are not given routinely. For example, influenza vaccine should be offered to children with serious chronic lung diseases. Influenza vaccine must not be confused with Hib vaccine.
Pneumococcal, varicella (chicken pox) and hepatitis A vaccines may be included in the immunisation schedule in future. Yellow fever vaccine is needed for international travel while rabies vaccine is given to children exposed to a bite from a rabid animal. To protect children, who have been exposed to serious infections, specific immunoglobulin is sometimes used. For example, hyperimmune immunoglobulin can be offered to children exposed to hepatitis B virus. The use of immunoglobulin is not as effective as immunisation as the protection is short-lived.
