Experts from Novosibirsk have developed a new vaccine against tick-borne encephalitis.

      The new medicine based on humanized antibody is several times more efficient than the popular immunoglobulin serum.

      According to scientists, present drugs are made of blood plasma taken from donors living in the areas of tick-borne encephalitis. Thus the patient receives not only the antibodies needed but a number of others, which may be harmful. Besides serum is potent only in big doses and therefore a human body may react negatively to high quantity of alien protein. Thereof specialists decided to invent a new medicine.

      They have developed the vaccine Encemab based on a chimeric antibody. While donor blood is required for getting immunoglobulin, the new medicine does not need it.
