In this paper, we explore an evolutionary vaccination game in the modified activity driven network by considering the closeness. We set a closeness parameter which is used to describe the way of connection between two individuals. The simulation results show that the closeness may have an active role in weakening both the spreading of epidemic and the vaccination. Besides, when vaccination is not allowed, the final recovered density increases with the value of the ratio of the infection rate to the recovery rate . However, when vaccination is allowed the final density of recovered individual first increases and then decreases with the value of . Two variables are designed to identify the relation between the individuals' activities and their states. The results draw that both recovered and vaccinated frequency increase with the increase of the individuals' activities. Meanwhile, the immune fee has less impact on the individuals' vaccination than the closeness. While the is in a certain range, with the increase of the value of , the recovered frequency of the whole crowds reduces. Our results, therefore, reveal the fact that the best of intentions may lead to backfire.

Pertussis (or whooping cough) has experienced a global resurgence despite widespread vaccine efforts. In China, the incidence of pertussis has rapidly increased, particularly following the COVID-19 pandemic. Whole-genome sequencing analysis was performed on 60 strains isolated in Beijing from 2020 to 2023, and the sequences were compared with those of 635 strains from China and 943 strains from other countries.

Background: Pertussis is a highly contagious respiratory disease caused by (BP). Despite global control of pertussis cases through the Expanded Programme on Immunization (EPI), there has been a significant increase in the incidence of pertussis in recent years, characterized by a "resurgence" in developed countries with high immunization rates as well as a comparable reemergence in certain areas of China. We aim to explore the genotypes and antimicrobial susceptibility of circulating BP from children in Hebei.

Introduction: This study, conducted in China prior to RotaTeq's launch, examined the epidemiological, molecular, and evolutionary features of the G1P[8] genotype RVA in children admitted with diarrhea, to aid in evaluating its efficacy and impact on G1P[8] RVA in China.
Methods: Data from the Chinese viral diarrhea surveillance network were collected from January 2016 to December 2018. RVA strains identified as the G1P[8] genotype were subjected to whole-genome sequencing.

Monkeypox (MPOX) is a zoonotic disease caused by Orthopoxvirus monkeypox (MPXV), belonging to the Orthopoxvirus genus, and exhibits symptoms similar to smallpox. In 2024, the monkeypox outbreak in the Democratic Republic of the Congo continued to develop, raising widespread global public health concerns. In September 2023, the first local monkeypox outbreak was reported in Nantong, Jiangsu Province, China.

Preventive vaccination is a crucial strategy for controlling and preventing infectious diseases, offering both effectiveness and cost-efficiency. However, despite the widespread success of vaccination programs, there are still certain population groups who struggle to mount adequate responses to immunization. These at-risk groups include but are not restricted to the elderly, overweight individuals, individuals with chronic infections and cancer patients.
