...never ensure a vaccine is completely safe," says Hugh Pennington, an emeritus professor of virology at the University of Aberdeen in Scotland. "Clinical trials are on the magnitude of thousands and can screen out common and mild reactions for the vaccine - fever and sore arms mostly. But if a vaccine causes a severe reaction in one in a million people, there's no way to test for that." (See pictures of swine flu hitting Mexico...
...pandemic, they say, the spread of H1N1 is inevitable. "They are not effective at all in my opinion," says Dr. Lo Wing-lok, a Hong Kong?based infectious-disease expert. "By picking up these few cases, there isn't any real impact in control of the flu." Hugh Pennington, a microbiologist at the University of Aberdeen, puts it more bluntly: "We are already in a pandemic. There's no containment option now." (See the 5 things you need to know about swine...
...invented - may actually work better for us than the occasional bouts of exercise you get as a gym rat. "You cannot sit still all day long and then have 30 minutes of exercise without producing stress on the muscles," says Hans-Rudolf Berthoud, a neurobiologist at LSU's Pennington Biomedical Research Center who has studied nutrition for 20 years. "The muscles will ache, and you may not want to move after. But to burn calories, the muscle movements don't have to be extreme. It would be better to distribute the movements throughout...
...swine flu become resistant to these drugs? Yes, and that's another reason why health officials will want to limit their use to those who have become ill with the disease, according to Hugh Pennington, a virologist at the University of Aberdeen. Resistance occurs when a virus mutates in such a way as to render a drug ineffective. This is more likely to occur when an antiviral is widely used because resistant mutations are more likely to thrive and be passed on. A similar process has led to the widespread existence of antibiotic resistant bacteria such as MRSA...
...think 1976 provides an example of how not to handle a flu outbreak, but what's interesting is that it made a good deal of sense at the time," says Hugh Pennington, an emeritus professor of virology at Britain's University of Aberdeen. Pennington points out that conventional wisdom in 1976 held that the 1918 flu pandemic - which started among soldiers and eventually killed as many as 40 million - was the result of swine flu (scientists now know it was in fact a strain of bird flu). Despite modern advances in microbiology, today's health officials still make decisions...
