简要总结

The study aims to investigate the safety and immunogenicity of one dose vs two doses of a T-cell priming next-generation vaccine against Coronavirus disease.

详细描述

The scale of the COVID-19 pandemic requires multiple vaccine candidates to ensure equitable and rapid access to protection by:

  • Providing a range of vaccine choices tailored to variations in immunological profiles across demographics as well as suited to environments with various levels of resources (cold chain etc).

  • Distributing and parallelizing manufacture, to speed up scale, avoid reagent stockouts and dilute monopolies

  • The ability for SARS -CoV-2 (Severe Acute Respiratory Syndrome Coronavirus-2) to mutate, requires multiple vaccine candidates to ensure robust and sustainable protection. Vaccines with a range of epitopes and immune targets provide immunological diversity and reduce vulnerability to mutant escape.

  • Nanotechnology fulfils the needs of a Universal Coronaviruses vaccine by being a rapidly scalable and modular platform

  • Humoral immunity may be transient and insufficient against emerging variants of SARS-CoV-2

  • Cellular immunity against SARS-CoV-2 is lasting and associated with recovery in COVID-19. A vaccine (prime or booster) inducing the right T cell response can be the solution against the need to develop new vaccines every time the virus mutates or a new variant persists.

This is a Phase I-II, double-blind, randomized, placebo-controlled study investigating the safety and immunogenicity of a T cell priming next-generation vaccine against Coronavirus disease in healthy adults.

The clinical study will enrol 110 participants (88 vaccine vera and 22 placebo, [split 50:50 between two groups one receiving one vaccination and the other two vaccinations]).
