In a number of projects at the UT, staff members and/or students work with human blood and/or blood products (blood cells). These projects involve a certain risk of accidental blood contact. This protocol is intended for the above staff members and students.
There may be blood contact if someone is injured by a contaminated needle or glassware. Splashes and aerosol formation may also cause contaminated material to enter the body via wounds, splits, eczema and via the mucous membrane of the eyes and mouth.
Based on Article 4.91 of the Working Conditions Decree, the working conditions policy rules provide that staff members in diagnostic and research laboratories who frequently come into contact with human blood or human blood products should be allowed by their employer to be vaccinated against hepatitis B (see Annex I).
Blood of (‘healthy’ or hospital) donors may contain viruses. The 'highest-risk' viruses are the hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV). A vaccination is only available against hepatitis B.
Hepatitis B is a serious form of liver infection. After an infection, 90% of infected people are able to overcome the disease with their own immune system; 10% of infected people are not able to do so. These persons will continue to be contagious (sometimes without them knowing) and later have an increased risk of liver cirrhosis (atrophy due to scarring) or liver cancer.
People are vaccinated against hepatitis B with a non-infectious vaccine containing HBV surface proteins obtained through genetic modification. The vaccine is administered through three injections at 0, 1 and 6-month intervals. A titre test (4 to 8 weeks after the final dose) should demonstrate if the vaccination has produced sufficient results. A vaccination offers protection for at least fifteen years.
The form contained in Annex II can be used to apply for this vaccination. The vaccination will be administered by HumanCapitalCare (the UT's Health and Safety department). Depending on the age of the person concerned and any previous vaccinations, the Health and Safety department will decide if a titre test should be performed first or if the 1st vaccination can be administered immediately. A vaccination card containing vaccination data will be issued afterwards. The faculty ensures that the registration card is registered. This card or a copy hereof must be stored for at least fifteen years.
