You're right. The devastating effects of the COVID‑19 pandemic on AIDS, tuberculosis and malaria have been well-documented. In fact, we have lost ground in the fight against the three diseases, which we have invested so heavily in over the past two decades.
It is true, however, that some positive things came of the COVID‑19 pandemic. As just mentioned, the investments required led to innovation, so the momentum generated by the pandemic sped up the development of vaccine technologies and other breakthroughs. Obviously, that gives us tremendous hope, since vaccines have yet to be found for all three of the diseases we target, even though they have been around for decades.
The potential for new technologies to be deployed—like mRNA vaccines, as you mentioned—and the fact that a number of labs are now exploring those possibilities are very positive developments. As you know, clinical trials are complex undertakings that often take many years, so we will have to wait and see, but we are cautiously optimistic.
One piece of positive news, however, is the World Health Organization's recent recommendation of the first-ever malaria vaccine. That is one more tool in our malaria toolkit. Of course, it has to be used in conjunction with other tools because it doesn't have a high enough efficacy rate to allow for indiscriminate use. In any case, there is progress in the fight against malaria, and it could help us step up efforts in the next few years.
