The threat of the current coronavirus disease pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is accelerating the development of potential vaccines. Candidate vaccines have been generated using existing technologies that have been applied for developing vaccines against other infectious diseases. ⋯ Updated information about immunological features from individuals who have or have not been exposed to SARS-CoV-2 continues to guide effective vaccine development strategies. This review highlights key strategies for generating candidate SARS-CoV-2 vaccines and considerations for vaccine development and clinical trials.

In France, 9-valent HPV vaccination is recommended routinely for 11-14-years-old girls and as catch-up for 15-19-years-old girls. Recently, recommendation for gender-neutral vaccination (GNV) has been approved. The objectives of the study were to assess the public health impact and cost-effectiveness of a 9-valent GNV compared with girls-only vaccination program (GOV). ⋯ In France, GNV has a significant impact in terms of public health benefits and may be considered cost-effective compared with GOV at low and high coverage rates.

Randomized Controlled Trial
Repeated exposure to an MF-59 adjuvanted quadrivalent subunit influenza vaccine (aQIV) in children: Results of two revaccination studies.
Pediatric adjuvanted seasonal influenza vaccines induce higher immune responses and have the potential to confer better protection against influenza among young vaccine-naïve children. Limited data describe benefits and risks of repeated administration of adjuvanted influenza vaccines in children. Two revaccination studies assess the safety and immunogenicity of repeated exposure to an MF59-adjuvanted quadrivalent influenza vaccine (aQIV; Fluad®) compared to routine non-adjuvanted quadrivalent influenza vaccine (QIV). ⋯ The safety and immunogenicity results from this study demonstrate benefit of aQIV for both priming and revaccination of children aged 12 months to 7 years.
