Background: A/H5N1 influenza virus spreads from birds to humans and cause influenza diseases with high mortality rate. Vaccination is the most effective way to protect communities from pandemic, reduce morbidity and mortality. The study of creating A/H5N1 influenza vaccines in conformity with Vietnam was the urgent need. Institute of Vaccine\u2019s Achievement (IVAC) studied production of inactivated influenza vaccine for human on egg-grown from reassortants NIBRG-14. Objectives: In order to produce experimentally A/H5N1 influenza vaccine for human in accordance with WHO requirements and set up a viable process for production of the vaccines. Subjects and method: 10 days embryonated eggs and NIBRG-14 strains were served to the study with LAL method to check endotoxin, Kijehdal method to test total protein. Results: IVAC had produced successfully 5 lots of absorbed vaccine A/H5N1 (FLUVAC) using NIBRG-14 strains and embryonated eggs. Initially, production and quality control processes had been set up at IVAC by applying the recommendations of WHO. Conclusion: The success of the study was a basis of the approval of the government to establish a influenza vaccine manufacturing facilities.

Numerous studies have also revealed that students with a high level of Nomophobia have an increased risk of depression. However, few researchers are interested in examining how the association between nomophobia and depressive symptoms mediates loneliness and self-control. This study aimed to investigate, among Vietnamese High School Students, the association between nomophobia and depressive symptoms, specifically focusing on the role that loneliness and self-control play as potential mediators of that relationship. The Nomophobia Scale (NMP-Q), Depression Anxiety Stress Scale 21 (DASS-21), The UCLA loneliness scale version 3 (UCLA III), and The Brief Self-Control Scale (BSCS) were completed by 556 Vietnamese high school students. Using the PROCESS macro, mediation analyses were conducted to investigate the relationship between variables. According to our findings, nomophobia was positively associated with symptoms of depression, and loneliness and self-control partially mediated this relationship. It is suggested that methods for preventing claustrophobia and depressive symptoms be taken seriously in order to increase self-control and decrease loneliness.
