The Gauteng Department of Health in South Africa has urged parents who might have missed their children’s immunisation dates due to the onset of Covid-19, to ensure that their children are immunised in order to protect them against diseases. “Young children from birth until the age of five are vulnerable to many infectious diseases such as polio, tuberculosis, hepatitis, measles, and meningitis. Immunisation helps prevent these diseases, as well as stimulate a child’s immune system to fight against infectious diseases later in life,” the department said in a statement to coincide with the African Vaccination Week which kicked off on Sunday, 24 April.
