The invention relates to the field of immunity against Coronaviruses. In this respect, the invention provides vectorized antigens derived from Coronaviruses that trigger an immune response against Coronaviruses. The invention accordingly relates to an active ingredient which is a live attenuated recombinant measles virus expressing Coronavirus antigen(s) and to its use in eliciting immunity, in particular protective immunity against SARS-CoV-2 strain and advantageously broad-spectrum protective immunity against various strains of Coronaviruses.

Disclosed are methods and compositions related to the use cannabinoids as adjuvants for the accelerated induction and production of an antibody based immune response.

An oral dissolving film containing nano- or micro-encapsulated bioactive material and methods of forming the film. The film may be prepared by dispensing a mixture of a film-forming agent, a crosslinking agent, a solution of nano- or micro-encapsulated bioactive material, and a photoinitiator into a plurality of wells in a tray using a 3D printer. The dispensed material is exposed to radiation in order to crosslink the material and form a film.
