Special Issue Information

Dear Colleagues,

The COVID-19 pandemic has revealed the need for an advanced vaccine pipeline to better deal with emerging diseases. Beyond the current situation and the approved vaccines, the necessities ahead, derived from human population diversity, virus evolution and the epidemiological situation, are uncertain. Fortunately, expanded technological possibilities in the field of vaccine generation are available, including established and new strategies. Vaccine qualities such as speed of generation, coding capacity, potency and safety must be considered when science is challenged with the task of developing new vaccines. Even though basic vaccination needs can be met with current COVID-19 vaccines, it is clear that the emergence of new variants, changes in virus pathogenicity or transmissibility and diversity in immunization scenarios and social constraints may require additional vaccine formulations. Of particular importance is the breadth of protection in light of virus diversity and the duration of such protection. In light of the considerable amount of work carried out in the field of vaccine technologies over the last years, much is to be learnt from the recent experiences of many research groups in vaccine design and testing, which may constitute a valuable resource for the future.

We are pleased to invite you to contribute to this Special Issue of Vaccines, entitled “COVID-19 vaccine candidate development”.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following: COVID-19 candidate vaccine design, construction and trials, and refinements or innovations regarding vaccine testing, both in animal models and in human clinical trials.

The Bacille Calmette-Guérin or BCG vaccine, the only vaccine available against Mycobacterium tuberculosis can induce a marked Th1 polarization of T-cells, characterized by the antigen-specific secretion of IFN-γ and enhanced antiviral response. A number of studies have supported the concept of protection by non-specific boosting of immunity by BCG and other microbes. BCG is a well-known example of a trained immunity inducer since it imparts ‘non-specific heterologous’ immunity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for the recent pandemic. SARS-CoV-2 continues to inflict an unabated surge in morbidity and mortality around the world. There is an urgent need to devise and develop alternate strategies to bolster host immunity against the coronavirus disease of 2019 (COVID-19) and its continuously emerging variants. Several vaccines have been developed recently against COVID-19, but the data on their protective efficacy remains doubtful. Therefore, urgent strategies are required to enhance system immunity to adequately defend against newly emerging infections. The concept of trained immunity may play a cardinal role in protection against COVID-19. The ability of trained immunity-based vaccines is to promote heterologous immune responses beyond their specific antigens, which may notably help in defending against an emergency situation such as COVID-19 when the protective ability of vaccines is suspicious. A growing body of evidence points towards the beneficial non-specific boosting of immune responses by BCG or other microbes, which may protect against COVID-19. Clinical trials are underway to consider the efficacy of BCG vaccination against SARS-CoV-2 on healthcare workers and the elderly population. In this review, we will discuss the role of BCG in eliciting trained immunity and the possible limitations and challenges in controlling COVID-19 and future pandemics. Full article
