Does routine pneumococcal vaccination of children provoke new patterns of serotypes causing invasive pneumococcal disease in adults and children?
Routine PCV7 decreased IPD in children but not in adults. Predominant STs changed--children exhibited fewer PCV7 STs and adults exhibited fewer PCV7 and PPV23 STs--reducing vaccine coverage and increasing the risk of replacement STs causing IPD in adults.
This study suggests that there was potential unmet mental health need in New York City 6 months after the September 11 attacks on the WTC, but these findings should be tempered by research showing an apparent decrease in population-rates of PTSD. In the aftermath of a disaster, interventions should target persons with mental health needs who were not previously seeking help from a professional for a mental health problem.
