As everyone knows that Swine Flu viruses that is Type A influenza viruses are very old, still no vaccines were ready to protect against flu pandemic as it takes longer duration to be manufactured. Current Swine flu has already spread in more than half countries in Asia, America and Europe region. To prevent this flu pandemic from rest of the world, Vaccine is the only solution. Considering the situation, some of the manufacturers already started manufacturing the vaccines last year itself.

While almost every American country is suffering by flu pandemic, US health officials declared on Friday, 25th September that the very first swine flu vaccine to arrive as early as October 5 in some doctors offices. This vaccine will be known as FluMist and it will be in the form of a nasal spray which is made from live weakened viruses and hence FluMist can’t be given to some groups like pregnant women, asthmatic and diabetic people etc. It can only be given to people ages 6 months to 24 years.

Since this first vaccines stock is arriving in relatively small numbers, and the cases of swine flu are soaring day by day, US health officials are trying to sort out who should be the first in the line to receive the vaccine. They analyzed this in order to get the best use of FluMist stock and get it to public. Based on this analysis, they have decided that the priority group is of health care workers and people who live with or care for children less than 6 months as they are too young to vaccinate.
