Message: [QUOTE="FGfrom50, post: 3120705, member: 8867"] Correct. There are literally thousands of viruses that cause a similar type of illness; cough/cold/sneezing/muscle aches. The flu jab protects against usually 3-4 of them. From what I understand, clever people analyse data from the Northern Hemisphere's flu season and try to predict which 4 are the most worth covering with the vaccine. Some years they do a better job than others. It doesn't protect you from every possible cold, it does protect you against 4 of the nastier ones that are likely to be the most common. [/QUOTE]
