The hope would be that the new vaccines are drastically more effective. The problem with assessing flu vaccine efficacy is that the uptake of the vaccine is so low because the flu vaccine often has significant side effects (it knocks me out for a day each time), and often doesn't even prevent you from getting the flu. At best, the flu vaccine as it is today, just reduces the severity of the disease (which is worthwhile for some populations).
