Hepatitis C Vaccine Hepatitis C virus is different from Hepatitis B virus, the former is an RNA virus, the latter is a DNA virus, the genome of the RNA virus is prone to mutation, which brings great difficulties to the development of the vaccine for Hepatitis C. At present, there is no effective vaccine for the prevention of Hepatitis C. Therefore, for the prevention of the transmission route of Hepatitis C, the vaccine is not available. There is no effective vaccine for the prevention of hepatitis C. Therefore, the prevention of the transmission route of hepatitis C is more important. Strict screening of blood donors: advocate free blood donation and strictly screen blood donors by testing serum hepatitis C antibody and ALT. This route has been effectively controlled since 1992 when blood donors were screened for hepatitis C antibodies. Transmission through broken skin and mucous membranes has become the main means of transmission, so more attention should be paid to the prevention of this pathway. For example, safe injection should be implemented, medical instruments should be strictly sterilized, and medical staff should wear gloves when contacting patients’ blood and body fluids. Educate and counsel intravenous drug users to quit. Do not share razors and dental tools, and strictly sterilize hair-cutting equipment, piercing and tattooing equipment. Sexually transmitted infections should be managed through regular check-ups for sexually promiscuous persons. People infected with hepatitis C virus are advised to use condom during sexual intercourse. Prevention of mother-to-child transmission For pregnant women who are RNA-positive for hepatitis C virus, amniocentesis should be avoided, delivery time should be shortened, integrity of the placenta should be ensured, and exposure of the newborn to maternal blood should be minimized.
