In-depth: Use of urine test for TB increasing

In 2015, the World Health Organization recommended a urine test that helps with the detection of tuberculosis (TB) in people living with HIV who are hospitalised or who have compromised immune systems. While uptake of this test in South Africa was initially quite slow, numbers presented at the recent South African TB Conference suggest that the use of the test is now increasing.

COVID-19: The role of next-generation vaccines in immunity

The results of a recent scientific trial have answered this question: Yes, using broadly neutralising antibodies. But what are broadly neutralising antibodies? How do they work? And when will the average person get access to them? Amy Green breaks down the science.
