Background: Since 1990, most US schoolchildren have received a second dose of measles-mumps-rubella vaccine (MMR2) at kindergarten entry. The objective of the present study was to evaluate the short- and long-term mumps immunogenicity of MMR2.
Methods: At enrollment in 1994-1995, children (n=308) in a rural Wisconsin health maintenance organization received MMR2 at age 4-6 years. A comparison group of older children (n=308) was vaccinated at age 9-11 years. Serum samples were collected over 12 years. Mumps antibody levels were evaluated by plaque-reduction neutralization (lowest detectable titer, 10).
Results: Before MMR2, the geometric mean titer (GMT) for the younger group was 33; no subject was seronegative, but 16% had the lowest detectable titer. In response to MMR2, the GMT tripled to 97, and the proportion with low titers diminished to 3%. Four-fold boosts occurred among 54%, but only 3% were positive for immunoglobulin M. Twelve years after MMR2, the GMT declined to 46, the proportion with titers
Conclusions: The mumps antibody response to MMR2 was vigorous, but over a 12-year period titers declined to levels similar to pre-MMR2 titers. No advantage was apparent in delaying MMR2 from kindergarten to middle school.

Background: Vaccine granulomas are a common (0.3-1%) adverse event (AE) of (accidentally) subcutaneously administered vaccines and specific immunotherapies containing aluminum conjugates. The clinical symptoms with persistent itching subcutaneous nodules, predominantly affect infants and young children on the lateral thigh.

The AEP 2025 Vaccination and Immunization Schedule recommended for children, adolescents and pregnant women residing in Spain features the following novelties: Due to the increase in measles cases and outbreaks in recent years, we recommend advancing the second dose of measles, mumps and rubella (MMR) vaccine to 2 years of age. As a consequence of the above, since many autonomous communities (ACs) use the quadrivalent vaccine for the second dose of MMR and varicella vaccines, we recommend, for all ACs, advancing the second dose of varicella vaccine to 2 years of age. Due to the very significant increase in cases of pertussis since late 2023 and especially in 2024, we recommend advancing the dose of Tdap given in adolescence to 10-12 years of age.

Anogenital warts (AGW) including multiple types of human papillomavirus (HPV) are prevalent. In this context, oncogenic HPV infection leads to anogenital cancers and the lesion is more persistent. Several research on AGW therapy with measles, mumps, and rubella (MMR) vaccine injections have been successful without adverse effects.

To determine the association between parental characteristics and MMR (measles-mumps- rubella) vaccination status of children in the United States. We conducted a cross-sectional study from July 2023 to April 2024 using a digital health survey via OutbreaksNearMe, weighted to target national population characteristics. We analyzed the responses of 19 892 parents of children younger than 5 years to examine the association between self-reported parental characteristics (i.

Objective: To estimate measles-mumps-rubella vaccination coverage, delay and loss to follow-up in children up to 24 months old living in Brazilian cities.
Methods: Surveys and questionnaires with a retrospective cohort of live births in 2017-2018, analyzing vaccination coverage and sociodemographic data of children and families, based on vaccination card records and interviews.
Results: Valid coverage of first dose was 90.
