RESUMO
We conducted a cohort study to assess vaccine effectiveness (VE) of coronavirus disease 2019 vaccine combinations on severe acute respirator y syndrome coronavirus 2 critical infection and death among elderly population in Korea. From Januar y to August 2022, VE against death for 4 doses mRNA recipients was 96.1%, whereas 1-dose viral vector + 3-dose mRNA recipients had VE of 90.8%.
RESUMO
In June 2022, the first monkeypox case was reported as imported into Korea. The general public asked whether they should get vaccinated against monkeypox because of the recent COVID-19 vaccination experience. As of the current monkeypox outbreak situation, a ring vaccination strategy for the high-risk group is more appropriate than the mass population vaccination with smallpox vaccines. Therefore, identifying the proper target group by available vaccines based on the risk and benefit analysis is a key issue of the vaccination program. In addition, the target group should be reviewed by the epidemiological situation of the jurisdiction along with the updated evidence of the monkeypox virus on transmission dynamics, severity, and fatality.
RESUMO
In an effort to improve the blood safety management system, Korea Centers for Disease Control and Prevention visited the national agencies and blood centers of foreign countries. In Japan, the management system for Human T-lymphotropic virus positive donors is operated. In Germany, Red Cross Blood Centers provide 75~80% of national blood consumption, and hospital blood centers provided 15~20%. In addition, the Paul Ehrlich Institut is engaged in blood center management and blood product safety, and the Robert Koch Institut manages transfusion-transmitted infection. The standard temperature of RBC transport is 1~10degrees C. In Austria, haemovigilance is operated by the National Blood Authority and adverse reactions following transfusion are investigated by Blood Centers. In Britain, blood is provided by National Health Service Blood and Transplant, and the Serious Hazards of Transfusion, haemovigilance system is operated. Universal leukoreduction has been performed since 1999 in order to prevent transmission of variant Creutzfeldt-Jakob disease.
