A Finnish hospital has come up with a new approach to the prevention of acute otitis media in children between one and three years the flu vaccine! The study showed that incidence of acute otitis media associated with flu was reduced by 83 per cent.
Meanwhile, the PRP conjugate vaccine against the Haemophilus influenzae type b (Hib), the most common cause of bacterial meningitis in the US and Europe, has only been found to be 74 per cent effective. (The Lancet, 17 August 1991)
Another study showed that the higher the dose of Hib vaccine, the lower the immunity to the disease.
