Active clinical trials for "Measles"

The purpose of this study is to see if the MMR and chickenpox vaccines work as well in premature infants as in children that were carried to full term. A group of children who were carried full-term will be matched for age, sex, and race and will be used for comparison.

This study will collect data on the safety of the MMRV vaccine (Priorix-Tetra™) used in routine practice in children aged 12 months to 12 years living in the Philippines.

On a previous study conducted in Brazil. The MMR vaccine from 2 different producers had a mumps seroconversion much lower (71%) than the expected 95%, according to the package insert. This could indicate that a substantial proportion of children was not protected after MMR dose.

Mortality rates caused by SARS CoV-2 differ between countries and this difference might be explained by several reasons. Childhood vaccination rate is thought to be one of them. Therefore present study aimed to examine the possible relationship between DTaP (diphtheria, tetanus, pertussis) and measles vaccination rates of Organization for Economic Co-operation and Development (OECD) countries and case fatality rate (CFR) caused by SARS CoV-2.

Prevalence of participants who have protective immunity to measles virus is less than ninety percent. Predictor of adequate measles antibody levels include the following : History of measles infection History of complete measles primary immunization( 2 doses with at least 1 month interval after age of 9 months) History of measles exposure Predictor of inadequate measles antibody levels include the following : Born outside Thailand History of staying outside Thailand for long time in childhood Living in the rural area for a long period in childhood Fail to participate school system on time

The question that this project seeks to answer, is whether mobile phones can be used to increase the measles vaccination coverage and timeliness in Guinea-Bissau. The intervention will be evaluated in terms of direct health outcomes and cost/benefit analysis, generating evidence that could help policy makers making informed decisions about implementing mHealth interventions at a national level. The intervention takes the form of a randomized controlled trial in which text messages (SMS) as well as voice calls are scheduled and delivered to mo thers to remind and encourage them to have their children timely vaccinated against measles. In addition, the messages will include relevant information about opening hours and availability of the measles vaccine at the mothers' local health facilities thus improving coordination. The trial will include three different randomization groups with approx. 350 participants in each group. The first group will receive SMS messages, the second group will receive a voice call in addition to the SMS messages, and the third group is a control group that does not receive any intervention. Study participants will be enrolled following birth at one of three health centers in different rural regions of Guinea-Bissau. Before the measles vaccine is scheduled to be given, at 9 months of age, mothers will receive the intervention message depending on their assigned randomization group. When the measles vaccine is administered, the child will be registered as having received the measles vaccination. A follow-up phone interview will be conducted at 12 months of age for all children participating regardless of randomization group and whether or not they received the measles vaccine. All participating children, who at that time still have not received the measles vaccine, will be offered the vaccine at the expense of the project.

Healthy children who received two doses of GlaxoSmithKline (GSK) Biologicals' live attenuated measles-mumps-rubella vaccine (MMR) or measles-mumps-rubella-varicella vaccine (MMRV) in their second year of life.The purpose of this study is to assess the effect of the age at administration of the first dose on the reactogenicity and immunogenicity of the measles component of these vaccines. In addition, this study will evaluate if the effect of the age at first dose is modified by the type of vaccine administered.

This is a randomized cross-sectional study of the Swedish population. Blood samples will be collected from a subpopulation in order to estimate the age specific sero-prevalence of the Swedish population for diseases included in the National Immunization Program (NIP), and to affirm the population's protection against polio. To be able to recommend complementary immunizations to immigrated children, a sub study focusing on foreign born teenagers will also be done and compared to children of the same age born in Sweden.

Maternal antibodies (measles and meningitis C) may wane in the first six months after birth. Geometric mean titers(GMTs) of measles and meningitis C. Follow-up on 0 month, 3rd month,5th month and 7th month after birth.
