Children under 6 and people older than 65 are groups at a high risk for contracting influenza and should receive QIV for better protection against the flu, doctors said.
There are two types of human flu, A and B, each with two subtypes. Vaccination for one type of flu does not provide protection against the other, doctors said.
The most commonly used trivalent influenza vaccines (TIV) usually protect against both strains in Type A, but only one in Type B.
When flu season comes, medical personnel will have to predict which of the two strains in Type B will be active, the doctors said.
But the predictions, which dictate what kind of TIV will be produced for the flu season, are sometimes wrong, the doctors said, adding that Taiwanese health authorities have guessed wrong four times over the past eight years.
