The Korean researchers say that the new flu vaccines now do not need any needles.This new vaccine may simply be placed under tongue.They further add that  new vaccine worked avoiding pain and the discomfort that some people from the inhaled vaccine.    

In tuesday's online edition of Proceedings of the National Academy of Sciences,the team leader Dr. Mi-Na Kweon of the International Vaccine Institute reported their findings in  Seoul

    Now, Kweon and colleagues say, two doses of influenza vaccine under the tongue of mice primed the animals' immune system to fight off what would otherwise have been a deadly dose of flu.Placing a couple of drops of liquid under the tongue gets the vaccine directly to mucus membranes and prompts a response both in mucus tissues throughout the body as well as in the immune system itself, the researchers said.
    
    Kweon has reported that The under-the -tongue vaccine worked on both whether it was a live or inactivated virus.She further added,it could also be given a flavored form to make it more acceptable by general people.

    So,guys who are afraid vaccine needle's prick just relax and don't worry for the vaccines otherwise if you are suffering from flu.
