Why the flu vaccine will never work: Experts reveal how the virus “mutates annually” into something new

The deadliest pandemic in recorded history was known as the Spanish flu, and took place between 1918 and 1919. About 500 million people – a third of the Earth’s population at the time – were infected with the disease, and it proved fatal for between 20 and 50 million of them. The outbreak started in Europe, but quickly spread to the U.S., Asia and the rest of the world. Over 675,000 Americans died, and surprisingly, the majority of them were young and healthy. Researchers later discovered that the reason it was so deadly was because that particular flu strain – the A H1N1 strain – quickly invaded victims’ lungs, causing pneumonia.
