Should you have two flu jabs this winter? Injection 'wears off faster than we think'

Earlier this year, Professor Stanley Plotkin, a pioneer of vaccines, revealed that he has two flu jabs. The 87-year-old, from the University of Pennsylvania, has one in early autumn, followed by another in December each year. The reason? The trusted flu jab, it seems, wears off far faster than we think. British experts agree that Prof Plotkin may be on to something. Also, over-65s will receive extra protection this winter because of a new type of ‘turbo-jab’: it is a new vaccine which protects against three or four strains of flu and also features an adjuvant. This bolsters the immune system’s response so that it releases a greater number of infection-fighting antibodies.
