Researchers found that biological differences between men and women can impact vaccine efficacy, with women typically generating a more robust protective immune response. This knowledge could inform strategies for optimizing vaccination programs, including the timing and dose of vaccines.
Researchers analyzed vaccination data and found only 35 reports of GBS following 2009 H1N1 vaccination, a rate of 3.5 per 10 million people vaccinated. In contrast, the seasonal flu vaccination in 2009 reported 57 cases, an estimated rate of 7.3 per 10 million vaccinations.
Researchers found that individuals with multiple social connections, or hub nodes, are more likely to vaccinate themselves and contain the spread of epidemics. 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 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.

A recent study suggests that prompt surveillance and containment of victims would be sufficient to thwart an epidemic in the event of a large bioterrorist US smallpox attack. Researchers found that mass pre-vaccination of the general population may not be necessary, as the benefits of vaccination are outweighed by potential side effects.
Researchers at Rockefeller University developed a modified HIV virus that can infect both human and monkey cells, paving the way for more effective vaccine testing. By manipulating key proteins, they created a 'simian tropic HIV' (stHIV) that replicates vigorously in primate cells.
