In light of encephalopathy presenting as autistic regression (autistic encephalopathy, AE) closely following measles-mumps-rubella (MMR) vaccination, three children underwent cerebrospinal fluid (CSF) assessments including studies for measles virus (MV). All three children had concomitant onset of gastrointestinal (GI) symptoms and had already had MV genomic RNA detected in biopsies of ileal lymphoid nodular hyperplasia (LNH).

Acellular vaccines against Bordetella pertussis were introduced in Australia in 1997. By 2000, these vaccines had replaced whole-cell vaccines. During 2008–2012, a large outbreak of pertussis occurred. During this period, 30% (96/320) of B. pertussis isolates did not express the vaccine antigen pertactin (prn). Multiple mechanisms of prn inactivation were documented, including IS481 and IS1002 disruptions, a variation within a homopolymeric tract, and deletion of the prn gene.

Doctors from the Cleveland Clinic Foundation and the Metro Hospital in Cleveland have found that children who have milk allergies may have an allergic reaction to DTaP containing vaccinations (diphtheria, acellular pertussis and tetanus). The vaccine is cultured on casamino acids derived from cow’s milk that could cause anaphylactic shock in children who are allergic to milk products.

iffering time schedules for childhood immunizations may explain the discrepant findings of an association with asthma reported in observational studies. This research was undertaken to determine whether timing of diphtheria, pertussis, tetanus (DPT) immunization has an effect on the development of childhood asthma by age 7 years.

Using the self-controlled case series design we examined 271,495 12 month vaccinations and 184,312 18 month vaccinations to examine the relative incidence of the composite endpoint of emergency room visits or hospital admissions in consecutive one day intervals following vaccination. These were compared to a control period 20 to 28 days later. In a post-hoc analysis we examined the reasons for emergency room visits and the average acuity score at presentation for children during the at-risk period following the 12 month vaccine.

Findings from animal and human studies confirm that diphtheria and tetanus toxoids and pertussis (DTP) and tetanus vaccinations induce allergic responses; associations between childhood vaccinations and subsequent allergies have been reported recently. The odds of having a history of asthma was twice as great among vaccinated subjects than among unvaccinated subjects

Influenza is known to be associated with asthma exacerbation but the effectiveness of the trivalent inactivated flu vaccine (TIV) in children, especially children with asthma, in preventing hospitalization is unknown. We assessed the effectiveness of the TIV in all children and especially children with asthma to prevent hospitalization with influenza. We conducted a nested case control study of all pediatric subjects (6 months to 18 years old) who were evaluated at the Mayo Clinic, Rochester, MN, who had laboratory-confirmed influenza during each flu season from 1999 to 2006 to evaluate the efficacy of TIV in preventing hospitalization.

We sought to determine whether there is an association between childhood vaccination and atopic diseases, and we assessed the self-reported prevalence of atopic diseases in a population that included a large number of families not vaccinating their children.
