So, if Mosquirix can potentially save lives or reduce illness now - even if only in one in three cases - then can we really justify holding off?
Given the vast scale of the number of people affected, we have a duty to fill these gaps in our knowledge Indeed, governments of malaria-affected countries are keen to see a malaria vaccine soon.For many countries malaria is a hugely important issue and a big drain on their economies.Not only does it kill 584,000 people every year, the vast majority being African children under the age of five, but through recurring sickness it takes many adults out of work for prolonged periods.All these factors conspire to make the WHO decision incredibly complex.The best way to get any clarity on these issues is to see how the vaccine performs in a real-life setting, in high and low transmission areas, with and without high coverage of other interventions.Normally this kind of post-market surveillance, or phase four trial, is used to gather additional long-term safety data.But for Mosquirix it now seems clear that this is the only way to find out definitively the role this vaccine has to play in reducing the disease burden of malaria.Currently, several phase four trials have been proposed for Mosquirix, some of which aim to shed more light on its effectiveness and the issues around the booster dose, yet none of these studies are fully-funded.That has to change. Most of the uncertainty surrounding this important vaccine concern questions that can be answered.Given the vast scale of the number of people affected, we have a duty to fill these gaps in our knowledge.
