...vary, and quite significantly. The Rochester study, for example, happened to look at the effectiveness of a vaccine during two seasons in which the flu strain included in the vaccine was not well matched to the predominant circulating strain that was making people sick. That could explain the lack of protection among the vaccinees - the shot may have been protecting against the wrong flu proteins. Targeting the correct strain is a always a bit of a guessing game, however; researchers make their best scientifically based prediction as to which flu virus will be making the rounds in a coming season...
Finally, notes Weinberg, who was not involved in the new study but is familiar with its design and results, the lack of effectiveness could have been due in part to the trial's small sample size. "The bigger numbers you have, the better," he says. "Five hundred subjects may sound like a lot, but once you start stratifying them by age, by whether they received all of their shots, or which year they were immunized, your total number gets smaller...
...lead in shots on goal over Yale, an advantage not seen in the final score. However, the margin did help to close the offensive gap between the Crimson and its opponents, as Harvard entered the contest with a 69-79 shot deficit for its season. The lack of scoring may have been slightly affected by external factors. Forceful winds plagued the Crimson during the first half of play, frequently sending the ball off course, and the general nature of the rival matchup aggravated aggressive tendencies. “It wasn’t the best performance...

Bailey said that one of the distinguishing features of Native American art is its lack of duplication. She said that the artists she works with do not even usually like to make earrings because it forces them to create two identical pieces. Bailey said that many Native Americans believe that nothing in nature is perfect, a sentiment that is reflected in their heterogeneous art. Bailey...
...people. We acknowledge, as Washington’s critics often point out, that American foreign policy is not perfect, but we believe that a healthy respect for the national interest can coexist with a policy of engagement and progress in the future.In particular, we are concerned about the lack of democracy and transparency in China’s nascent civil society. Recently, we were devastated by reports that infant formula tainted by melanine was responsible for the poisoning of thousands of Chinese infants, and that candy contaminated by the same chemical had reached American shores. We urge policymakers on both...
