Takeaway: This is the first human study of its kind, and illustrates the key role our gut bugs play in determining our immune response, as well as how our microbiome can impact the success – or failure – of medication. If you plan to receive the flu vaccine (and even if you don’t!), avoiding antibiotics is an important step in cultivating a strong, responsive immune system.
