Three decades of attempts to create a vaccine against hiv, the virus that causes aids, have proved fruitless. Moderna, a firm based in Massachusetts that has recently found fame by quickly coming up with a viable covid-19 jab, is planning to start human trials of a novel vaccine against hiv. Its researchers hope that the mrna technology used to produce its covid-19 jab will succeed against hiv too, by creating a vaccine which the virus cannot easily dodge. Is this the turning point for fighting the HIV AIDS Vaccine ?
