Enabling the evaluation of COVID-19 vaccines with correlates of protection.

In February 2023, a meeting about correlates of protection (CoPs) against COVID-19 was organized by the International Alliance for Biological Standardization, the European Plotkin Institute for Vaccinology, and Vaccinopolis. The meeting aimed at reviewing the evidence, drawing conclusions, and identifying knowledge gaps. Collection of evidence is not straightforward.

Establishment of an HLA-A*0201 human papillomavirus type 16 tumor model to determine the efficacy of vaccination strategies in HLA-A*0201 transgenic mice.

With the increasing generation of new cancer vaccine strategies, there is also an increasing demand for preclinical models that can carefully predict the efficacy of these vaccines in humans. However, the only tumor models available to study vaccines against human papillomavirus (HPV) 16 have been developed in C57BL/6 mice. To test the HLA-restricted capabilities of vaccination strategies, it is important to establish a tumor model in HLA-A*0201 transgenic mice.
