Russian medics inform that new domestic anti-flu vaccine, which causes no allergy in patients, will appear in two or three years.
      
      Existing domestic anti-flu vaccines, which are also used within annual immunization schedule, are prepared with egg proteins, which sometime cause allergy and complications, especially with children, who are often intolerant to such proteins.
      
      In two years Russian vaccine producers will introduce new technology for allergy-free vaccine, suiting both children and adults. Medics also warn that vaccination is a good way to prevent flu pandemics.
