2-dose varicella vaccination has been available in Ningbo city, China since 2014 in the private sector. This study aimed to evaluate the breakthrough varicella infection rate, and to examine overall and incremental effectiveness of 2-dose varicella vaccination among Chinese children.A retrospective investigation was done among native children born from 2008 to 2013 in active surveillance area in Ningbo,...
Few measles outbreaks among adults are reported in China, and outbreak response costs are seldom documented. We report an adult measles outbreak and response in 4 linked office buildings in Beijing and its associated costs.The World Health Organization measles case definitions were used to determine suspected and confirmed measles cases. Surveillance data were used to describe the outbreak, and records...
Age-appropriate receipt of ≥2 measles-containing vaccine (MCV) doses has been considered evidence of immunity against measles. Transmission of measles is rarely reported among such persons.We report a measles outbreak in a middle school in Beijing that has high coverage with≥2 documented MCV doses. History of previous measles and documentation of MCV receipt were collected for all individuals. Cases...
An outbreak of measles occurred in early 2014 among individuals not targeted for vaccination—adults, and infants too young to vaccinate, in Xiangshan County, Zhejiang Province, in eastern China.We conducted an investigation to identify risk factors responsible for this outbreak and to provide evidence-based recommendations for measles elimination strategies in China.Measles was diagnosed using national...
110 children who were given the complete course of the inactivated hepatitis A vaccine (Havrix™) were followed up 10 years later. Age-matched healthy children who were not inoculated served as controls. One month after two primary injections, all children were positive for serum antibody. After 10 years, 99.09% of inoculated children remained positive for serum anti-HAV antibody, with a geometric...
To properly evaluate the immunization status and determine risk factors of migrant children in 23 densely populated towns and townships in Beijing.A household cluster sampling survey was implemented and standard face-to-face interviews were conducted with 1820 migrant children aged 12–35 months. Demographic characteristics of the child and primary caregiver, the child's migrant characteristics, the...
Cellular immune response plays an important role in antiviral immunity. In our previous study, immunization of mice with severe acute respiratory syndrome coronavirus (SARS CoV) spike (S) DNA vaccine could induce both humoral and cellular immunity in response to a pool of entire overlapping S peptides. Identification of functional dominant epitopes in SARS CoV S protein for T cells is crucial for...
An effective vaccine for severe acute respiratory syndrome (SARS) will probably require the generation and maintenance of both humoral and cellular immune responses. It has been reported that after natural infection in humans and immunization in animals with SARS-CoV vaccine, antibody is produced and persistent for a long period of time. In the present study, mice were immunized i.m. with SARS-CoV...
