The great reduction of measles incidence is directly attributed to a good routine coverage with measles vaccine in Northern Viet Nam from 1986 to 1997. We have some remarks on measles in 1996-1997: Measles has been reported in all provinces in the North of Viet Nam. Measles has occurred in all seasons but the peak has been in spring and the lowest incidence has been in summer and fall. Measles distribution by age has been changed. Most of the reported cases were from 5 to 14 years old. 69% of cases were not immunized

Analysis of measles data of the Northern region in 2000 indicated that the disease spread widely in all provinces and all the year round. However, it mostly occurred in spring, and in this season measles outbreaks were also often recorded, 36 out of 48 measles outbreaks were confirmed by serological diagnosis. Most of the measles cases were recorded in age group 5-15 years old. Most of the measles cases in immunized children were in the age group 5-9 years. The results: the confirmed measles cases appeared in big cities, delta provinces as well as in midland and mountainous provinces. There was no significant difference regarding sex. The symptoms usually observed in the measles cases were fever, cough, coryza, rash and conjunctivitis

Background: Measles vaccine was the only vaccine in the expanded vaccination program still must be imported. Center for research and production of vaccines and biologicals \ufffd?Ha Noi was conducting the first stages of measles vaccine manufacturing technology transfer from the Kitasato Institute in Japan. The Center received semi-finished vaccine to set up finished vaccine production process as well as the testing process. Potency test and its consistency is very essential in quality control. Objectives: In order to identify standard potency assessment methods and potency of 13 lots of finished measles vaccine produced in Viet Nam from imported semi-finished products. Subjects and method: 13 lots of the finished vaccine were determined potency by plaque method based on 13 samples of semi-finished vaccine and the standard sample M16-6 had potency from 4.2 to 4.6 lg PFU/0.5 ml provided by the Kitasato Institute. Results: The result of 13 lots show that the reduction of potency during freeze-drying is within the range (0-0.76 lg); and 4 last consecutive lots are met WHO criteria on heat stability. Conclusion: This shows that the measles vaccine freeze-drying process in Vietnam was officially set up to use for the measles vaccine production in 2007.
Measles Vaccine/ diagnostic use

The study included 890 children from 2 to 10 years of age in Thanh Hoa province. The seroconversion rate to measles vaccine increased from 61% to 83% after the booster dose of measles vaccine. Antibody mean titer significantly increased from 14.9+/-10 PANBIO units to 18.6+/-7.6 PANBIO units. The increase was high significant in negative sera. Antibody mean titer varied by districts. However, antibody response to measles vaccine signigicantly increased after the 2nd dose of measles vaccine in all the districs

Introduction: Children who develop any hypersensitivity reaction to eggs are routinely referred to hospital for Measles-Mumps-Rubella (MMR) vaccination as inpatients to prevent anaphylaxis. We aimed to study the association between hypersensitivity reactions after egg exposure and similar reactions after MMR immunisation; and examine the necessity of hospital admission for vaccination. Methods: A prospective observational study was conducted in Paediatric Department in Bukit Mertajam Hospital, Penang, between March and December 2014. Children referred from local polyclinics for inpatient MMR vaccination because of a history of egg allergy were recruited. The children were observed in the ward for post vaccination allergic reactions. Concurrently, a group of children without egg allergy was recruited from those admitted for other illnesses but had recent MMR vaccination at polyclinics. Parents of these children were interviewed and asked if they had observed any reactions post vaccination. In both groups, sociodemographics, medical history and family history of atopy were collected. Results: Eighty-seven subjects were recruited in this study. Fifty-four infants with egg allergy had previous mild allergic reactions after exposure to eggs or egg-related products. They were associated with a family history of egg hypersensitivity, personal history of acute gastroenteritis and upper respiratory tract infections. Two of them developed cutaneous rashes post vaccination during observation, but none developed anaphylactic or anaphylactoid reactions. Two infants among those without egg allergy had post vaccination fever. There was no association between egg allergy and hypersensitivity reactions to MMR vaccine (p=0.632). Conclusions: MMR vaccine can be safely administered to children with mild egg allergy, hence admission for vaccination in the hospital is not warranted. Risk stratification is required to ensure only infants with severe reactions will be admitted for vaccination.
Measles-Mumps-Rubella Vaccine

A study on 99 cases of measles at the beginning of the year 2000 in Dong Thap province (52 male, 47 female, the average age of 5,5). 38 cases had complications. The distribution by age: there were 5 cases under 4 months old, 4 cases from 9-11 months old, 29 cases over 1 year old. 59 cases had been vaccinated, in which 34 cases had vaccinated with day identified on card or number of vaccination and 25 cases of vaccination, but the vaccinated day was not determined.

Measles has been declared eliminated from the Korea since 2006. In April 2014, a measles outbreak occurred at a University in Seoul. A total of 85 measles cases were identified. In order to estimate vaccine effectiveness of measles vaccine, we reviewed the vaccination records of the university students. The vaccine effectiveness of two doses of measles containing vaccine was 60.0% (95% CI, 38.2–74.1; P < 0.05). Transmission was interrupted after the introduction of outbreak-response immunization. The outbreak shows that pockets of under-immunity among college students may have facilitated the disease transmission despite the high 2-dose vaccination coverage in the community.
