At the age of 2–6 months, 30% of premature and 46% of children with congenital heart defects were vaccinated with the PCV7/PCV13 vaccine; at the age of 7–11 months, 52 and 40%, respectively. In 65% of cases, the PCV7/PCV13 vaccine was administered together with other vaccines in the national preventive vaccination schedule. The frequency of general post-vaccination reactions (increase in body temperature from 37.6 to 38.0°C) was 4%; no local reactions were recorded. No other adverse events were noted in the post-vaccination period.</p> Salomov Shoxabbos Nozimjon o’g’li Bustonov Sherzod Copyright (c) 2024 https://creativecommons.org/licenses/by-nc/4.0 2024-02-20 2024-02-20 21 37 39 SYNTHESIS OF SOME FERROCENE DERIVATIVES https://americanjournal.org/index.php/ajtas/article/view/1877 <p>The article provides information on the production of ferrocene and its derivatives, their physical and chemical properties, and their practical importance.
