Summary: The 2009 swine flu pandemic exposed the limitations of egg-based vaccines in terms of global supply, prompting the urgent need for efficient new vaccine platforms; DNA vaccines have since been developed as a temperature stable, cost-effective option for pandemic responses, capable of inducing rapid protective immune responses without the need for adjuvants.

Summary: Individuals living with HIV often show poor responses to influenza vaccination despite viral suppression through antiretroviral therapy. This study focused on identifying immune correlates of vaccine response in HIV-infected pediatric and adolescent individuals, with differences in gene expression patterns and pathways observed between high and low antibody responders. Age was also found to play a role in the immune responses, with older individuals exhibiting enriched gene pathways associated with T follicular helper cells following vaccination. These findings provide valuable insights for the development of improved vaccine strategies in HIV-infected children across different age groups.

Summary: The study investigated the association between parental socioeconomic and psychosocial factors and the uptake of the 2009 pandemic influenza vaccine in children. It found that children of younger and less educated mothers had a lower rate of vaccine uptake. However, the individual or relational psychosocial well-being of parents was not associated with children's vaccination.

Summary: The COVID-19 pandemic has led to rapid investigation and deployment of vaccine platforms never used before. Both new and existing vaccine platforms are likely to play a crucial role in combating future pandemics, especially influenza. The field of influenza vaccine manufacturing has a long history of successes and advancements in the past decade.

Summary: A meta-analysis was conducted on the immunogenicity of H5N1 influenza vaccines in elderly adults. The results showed that two doses of vaccines resulted in higher antibody responses, and the use of Oil-in-water emulsion (OE)-adjuvanted 7.5 μg vaccine was more effective than 3.75 μg vaccine.

Summary: Controlling avian influenza viruses (AIVs) is mainly done through culling infected bird flocks or using inactivated vaccines. New avian influenza virus subtypes have been reported in Egypt, calling for an updated vaccine. In this study, three H5Nx vaccines were generated using reverse genetic system, and their immunogenicity and cross-reactivity were assessed. The results showed that rgH5N1_2.3.4.4 vaccine induced high immunogenicity and provided efficient protection against different H5Nx HPAIVs.

Summary: H5N1, a highly pathogenic avian influenza virus, circulates in many Asian countries and a safe and effective vaccine is needed to prevent outbreaks in humans. JPV, a nonsegmented negative-strand RNA virus, has been explored as a promising vaccine vector and has shown efficacy in inducing immune responses in animals. NNSVs like JPV can stably express foreign genes and replicate efficiently in the respiratory tract.
