This voluntary vaccination method can lead to periodic outbreaks, but ultimately settle into a stable state due to the majority of individuals choosing vaccination.
Researchers at NIST found that standard-sized refrigerators without freezers outperform smaller, dormitory-style refrigerators in storing vaccines. The study identified several best practices for vaccine storage, including keeping vaccines away from the door shelves and walls to prevent temperature drifts.
A recent study found that refusing immunizations increases the risk of varicella illness in children, with unvaccinated kids nine times more at risk. The study analyzed electronic health records of over 86,000 children and confirmed that vaccine refusal significantly raises the risk of infection.
A new study found that pneumococcal vaccines for otitis media in children have not curbed the rate of complications, with lateral sinus thrombosis and epidural abscesses being common issues. The research, presented at the AAO-HNSF Annual Meeting, suggests a shift in focus from treating complications to understanding what may arise.
Researchers suggest vaccinating children could be an effective way to support pandemic control measures. Vaccination programs for children would offer protection not only to those at greatest risk but also to unvaccinated adults, reducing the need for vaccines in the general population.
Researchers suggest targeting children for flu vaccination to support control measures and reduce pandemic spread. Vaccinating key individuals in households provides sufficient protection to others, potentially reducing the need for widespread vaccination.
