Agnirva Space Premier League - Expedition #31762: Fighting Superbugs in Space: The MRSA Vaccine Experiment

Methicillin-resistant Staphylococcus aureus (MRSA) is a notorious hospital superbug. But can space help us fight it? The National Laboratory Pathfinder Vaccine experiment investigated this by studying MRSA aboard the ISS.

Led by Dr. Timothy Hammond, the research aimed to understand how the bacteria grows and evolves in microgravity. Bacteria behave differently in space—often becoming more virulent. This makes the ISS a powerful lab for testing treatments.

Scientists exposed MRSA strains to space conditions and studied their gene expression, metabolism, and resistance profiles. The ultimate goal: develop a more effective vaccine.

Why space? Without gravity, stress responses in microbes become more pronounced, potentially revealing new vaccine targets or drug mechanisms.

This work could improve infection control in space missions and hospitals on Earth, offering new hope against antibiotic-resistant bacteria.
