I just took a booster dose of a vaccine concoction to help prevent traveler's diarrhea caused by E.coli during my trip to Mexico. Luckily, I only needed a single dose this time, as opposed to the usual two doses of Dukoral, which definitely made the process a bit easier. I've shared the preparation method in this video for anyone interested in seeing how it's done. It was a bit of a challenge; it took me three attempts to successfully get it all down, but I managed it. Go me!
