Crippled fungus acts as vaccine

Even if your immune system can fend off harmful bacteria, viruses, and parasites, you still

have fungi to fear. Worldwide, millions of people suffer debilitating and even fatal fungal infections.

People with weakened immune systems, such as the elderly and AIDS patients, are particularly

susceptible.

Despite this threat, there’s not a single fungal vaccine available for human use, and microbiologists

were for a long time pessimistic that there ever would be.
