Introduction: Malaria remains a significant burden, and a fully protective vaccine against is critical for reducing morbidity and mortality. Antibody responses against the blood-stage antigen Merozoite Surface Protein 2 (MSP2) are associated with protection from malaria, but its extensive polymorphism is a barrier to its development as a vaccine candidate. New tools, such as long-read sequencing and accurate protein structure modelling allow us to study the genetic diversity and immune responses towards antigens from clinical isolates with unprecedented detail.

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of tartrazine as sensory additive (functional group: (a) colourants: (i) substances that add or restore colour in feedingstuffs). Tartrazine is intended to be incorporated in fishing baits up to a maximum of 30 mg/kg in complementary feed in order to colour them and attract fish in freshwater (ponds, rivers), for both recreational and competitive fishing. The additive is not intended for use in aquaculture.

Propionic acid is currently authorised as a technological additive (functional group: silage additives) for all animal species. The applicants requested for the renewal of the authorisation of propionic acid when used as a feed additive for all terrestrial animal species. The applicants have provided evidence that the additive in the market complies with the conditions of the authorisation.

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of NCYC R618 as a zootechnical feed additive (functional group: gut flora stabiliser) for chickens for fattening and other poultry species for fattening and reared for laying. The additive has never been authorised. The strain under assessment (NCYC R618) qualifies for the qualified presumption of safety (QPS) and, consequently, the FEEDAP Panel concluded that the product is safe for the target species, the consumers and the environment.

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the assessment of the application for the renewal of the authorisation of fumaric acid as a technological and sensory additive (functional groups: preservative and flavouring compounds, respectively) and for a new use of the additive as a technological additive (functional group: acidity regulator) for all animal species. The applicant provided evidence that the additive currently in the market complies with the existing conditions of authorisation. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that fumaric acid remains safe under the authorised conditions of use for the terrestrial animals, consumers and the environment.
