`Social media' has become `hot cake' these days, as every passing day gifts a new use of it to the world, and thinking it to be the same way, Penn State University's Assistant Professor of biology, Marcel Salathe chose social media to conduct her research.

His aim was to use the twitter as a base for study and to analyze the spread of H1NI virus and view of the users in relation to its vaccination. Initially, he started with correlation in which he took two measures, users' thinking and vaccination rates. And, after knowing the co relation between both of them, his second step was to know perception of users after they read micro-bloggers about H1N1 virus.

The study that got published in the `journal Public Library of Science Computational Biology' revealed that social media is one of the effective and economic way to reach to wide audience without getting tensed about geographical boundaries. The article that accompanied the research said that Marcel chose `Twitter' over ` Facebook' for two simple reasons, and those were that in Twitter one could use tweets as source of data, which is not possible in Facebook, and the second reason was that tweets represents true sentiment in precise words.

He collected views about the virus, then perception about its vaccine, and found that New England had `had the highest H1N1 vaccination rate and people like to tweet with those, whom they think would have same thinking.
