[Immunisation against influenza with a new subunit vaccine tested on children at risk (author's transl)]

Abstract

The efficacy and tolerance of Sandovac, a new subunit vaccine, was tested in 104 children and juveniles aged 2 1/4 to 17 years, at five children's clinics. Sandovac 1000 was given to 39 children, Sandovac 2000 to 65. The vaccine was well tolerated, no appreciable side effects--local or systemic--having been recorded. The efficacy of Sandovac was checked by determining the antibody titre against haemagglutinin and neuraminidase in 36 children before and 28 days after vaccination with SAndovac 1000. The conversion rate with haemagglutination-inhibiting antibody titres type A strain Victoria was 100% and type B strain Hong Kong 86%. The geometric mean values rose by a factor of 29 for type A and 7.4 for type B. For the neuraminidase-inhibiting antibodies the factors were 3.15 with type A and 5.83 with type B. Titre increases by a factor of at least 1.5 occurred in 75 and 84%, respectively of vaccinated children.
