They are produced in biotechnological eukaryotic yeast-based systems and contain the S-protein domain of HBsAg particle in the complete absence of pre-S1 and pre-S2 domains. At the same time, these antigens were proved to significantly influence immunogenicity, which makes the development and use of third-generation vaccines containing all antigenic determinants a long-range objective. A randomized, double-blind clinical study was conducted to compare immunogenicity of second- and third-generation vaccines Engerix-B™ and Sci-B-Vac™, respectively. Healthy subjects of both sexes aged 18 to 45 years (n = 94) who are seronegative for HBsAg, HBsAb, HBcAb at screening and who previously had not received immunobiological agents for hepatitis B prophylaxis were included in the study. Group I (n = 47) received the second-generation vaccine Engerix-B™, Group II (n = 47) — the third-generation vaccine Sci-B-Vac™. Subjects received vaccines three times — on days 1, 28 and 180 of the study. HBsAb levels, rates of seroconversion (the proportion of subjects with HBsAb levels &gt; 2.1 mIU/mL) and seroprotection (the proportion of subjects with HBsAb levels ≥ 10 mIU/mL) were assessed on days 28, 90, 180 and 210 of the study. Early seroconversion rate assessed on Day 28 was 76.60% in Group I and 93.88% in Group II (p &lt; 0.05); seroprotection rate was 51.06 and 61.22%, respectively. These differences in the proportion of subjects who achieved seroconversion on Day 28 may indicate a faster immunological response to Sci-B-Vac™ vaccine. Statistically significant differences between the level of antibodies on days 90 and 180 (p &lt; 0.05) were observed when analyzing the average values of HBsAb concentration in Groups I and II. The concentration of HBsAb on Day 90 was 378.68±60.95 mIU/mL in Group I, and 618.31±58.34 mIU/mL in Group II. On Day 180, the concentration of HBsAb reached 441.34±63.83 mIU/mL in Group I, and 757.72±55.14 mIU/mL in Group II. The significance of dependence of antibody level on sex, age and body weight was analyzed. It was revealed that the age of a vaccinated subject affects antibody level after administration of Engerix-B™ (p &lt; 0.05). The results obtained suggest that there is a rapid and strong immune response to the third-generation vaccine Sci-B-Vac™. This may indicate advantage of the vaccine containing all three recombinant proteins of hepatitis B virus envelope, which, in turn, can play a key role in clinical practice for urgent prophylaxis of hepatitis B, as well as for treatment of immunocompromised conditions.</p></abstract><trans-abstract xml:lang="ru"><p>В настоящее время широко используются вакцины против гепатита В второго поколения, получаемые в биотехнологических эукариотических системах на основе дрожжей и содержащие S-белковый домен частицы HBsAg при полном отсутствии доменов pre-S1 и pre-S2. Вместе с тем доказано, что именно эти антигены могут значительно влиять на иммуногенность, что делает разработку и использование вакцин третьего поколения, содержащих все антигенные детерминанты, перспективной задачей. Для сравнительного изучения иммуногенности вакцин второго и третьего поколений Engerix-B™ и Sci-B-Vac™ было проведено рандомизированное двойное слепое клиническое исследование. В исследование были включены здоровые лица обоих полов в возрасте от 18 до 45 лет (n = 94), cеронегативные в отношении HBsAg, HBsAb, HBcAb при скрининге и ранее не получавшие иммунобиологические средства профилактики гепатита В. В группу I (n = 47) вошли лица, получившие вакцину второго поколения Engerix-B™, в группу II (n = 47) — вакцину третьего поколения Sci-B-Vac™. Вакцинация осуществлялась трехкратно — в 1, 28 и 180 дни исследования. Концентрация HBsAb, показатели сероконверсии (доля лиц с концентрацией HBsAb &gt; 2,1 мМЕ/мл) и серопротекции (доля лиц с концентрацией HBsAb ≥ 10 мМЕ/мл) оценивались на 28, 90, 180 и 210 день исследования. При оценке показателя ранней сероконверсии на 28 день исследования установлено, что он составил 76,60% в группе I и 93,88% в группе II (p &lt; 0,05); показатель серопротекции составил 51,06 и 61,22% соответственно. Данные различия в отношении доли лиц, достигших сероконверсии на 28 день исследования, могут свидетельствовать о наступлении более быстрого иммунологического ответа на введение вакцины Sci-B-Vac™. При анализе средних значений концентрации HBsAb в группах I и II были получены данные о наличии статистически значимых различий между уровнем антител на 90 и 180 день исследования (p &lt; 0,05). На 90 день исследования в группе I концентрация HBsAb составила 378,68±60,95 мМЕ/мл, в группе II — 618,31±58,34 мМЕ/мл. На 180 день исследования в группе I концентрация HBsAb достигла 441,34±63,83 мМЕ/мл, в группе II — 757,72±55,14 мМЕ/мл. Проведенный анализ значимости зависимости уровня антител от пола, возраста и массы тела выявил, что возраст вакцинированного влияет на концентрацию антител после вакцинации Engerix-B™ (р &lt; 0,05). Таким образом, полученные результаты позволяют сделать вывод о наличии быстрого и сильного иммунного ответа на введение вакцины третьего поколения Sci-B-Vac™, что может свидетельствовать о преимуществе вакцины, содержащей все три рекомбинантных белка оболочки вируса гепатита В, что, в свою очередь, может сыграть решающую роль в клинической практике при экстренной профилактике гепатита В, а также при использовании у пациентов с иммунокомпроментированными состояниями.</p></trans-abstract><kwd-group xml:lang="en"><kwd>hepatitis B</kwd><kwd>vaccine</kwd><kwd>Sci-B-Vac™</kwd><kwd>immunogenicity</kwd><kwd>seroconversion</kwd><kwd>seroprotection</kwd><kwd>pre-S1/pre-S2/S</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>вакцина</kwd><kwd>гепатит В</kwd><kwd>Sci-B-Vac™</kwd><kwd>иммуногенность</kwd><kwd>сероконверсия</kwd><kwd>серопротекция</kwd><kwd>pre-S1/pre-S2/S</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
