Dr Cristina Vilaplana is a medical doctor passionate about helping patients with tuberculosis (TB). Her research could make a difference to a lot of people.

July marks the 100-year anniversary of the Bacille Calmette-Guérin vaccine (BCG), still the only approved vaccine against TB. More than a dozen vaccines for TB are currently being tested in clinical trials: some use whole bacteria as BCG does, while others deliver protein subunits or genetic material carried by viral vectors. 

Studies are underway to test whether giving a shot of BCG vaccine could protect doctors and nurses against COVID-19.
