The present invention is directed to a nucleic acid suitable for use in treatment or prophylaxis of an infection with a coronavirus, preferably with a Coronavirus SARS-CoV-2, or a disorder related to such an infection, preferably COVID-19. The present invention is also directed to compositions, polypeptides, and vaccines. The compositions and vaccines preferably comprise at least one of said nucleic acid sequences, preferably nucleic acid sequences in association a lipid nanoparticle (LNP). The invention is also directed to first and second medical uses of the nucleic acid, the composition, the polypeptide, the combination, the vaccine, and the kit, and to methods of treating or preventing a coronavirus infection, preferably a Coronavirus infection.

A method for detecting MERS-CoV at high sensitivity and specificity using IgY antibodies that bind to MERS-CoV N protein, its fragments and domains. Isolated or purified IgY monospecific antibodies to MERS-CoV N protein.

The present invention relates to mRNAs suitable for use as mRNA-based vaccines against infections with MERS coronaviruses. Additionally, the present invention relates to a composition comprising the mRNAs and the use of the mRNAs or the composition for the preparation of a pharmaceutical composition, especially a vaccine, e.g. for use in the prophylaxis or treatment of MERS coronavirus infections. The present invention further describes a method of treatment or prophylaxis of infections with MERS coronavirus using the mRNA sequences.

Provided are devices, systems and methods for determining whether a patient is immune to an infection or a disease caused by a coronavirus, such as severe acute respiratory coronavirus 2 (SARS-CoV-2). Devices and systems described herein are cost effective, scalable, and may be used at the point of need or point of care without a specialized training. The systems and devices described herein are useful for vaccine development, screening convalescent plasma therapies, and for identifying individuals who are eligible for reintegration following a period of quarantine.

Described herein are systems and methods for detecting and quantifying analytes. Also described herein are systems and methods for detecting and quantifying analytes stemmed from infections.
