TB is a nasty disease that can only be transferred by close contact with people. The policy of the health service has been to only offer vaccination to people who have family contacts with areas with high levels of TB. That is because the vaccination itself is not something people would like. I have for some time argued that there is a risk of a disease vector at school and that schools which have a high proportion of children who qualify for the vaccination should offer it to all of the children at that school. The sad death of Alina Sarag (who was at a school which is (just) in my constituency, but who lived outside the constituency) makes it clear that there is a risk of a disease vector at school. That is why we need to consider this particular category. I argued this before she was infected.
