The invention discloses a bat-derived coronavirus vaccine for preventing COVID-19. The bat-derived coronavirus Bat / CovRaTG13 is adopted to produce the vaccine so as to control and prevent the ongoingCOVID-19 pandemic and the future epidemic of the disease. The genetic fingerprint of the Bat / CovRaTG13 is closest to the genetic fingerprint of the 2019 new coronavirus (SARS-CoV-2). Homology of all amino acid sequences not only determines the genetic relationship, but also determines the similarity of biological characteristics, and antigenicity is one of main factors for determining specificityand effectiveness of the vaccine. The vaccine strain comes from a Bat / CovRaTG13 family member, and has sequence homology. The bat coronavirus-derived vaccine can be prepared into three types of vaccines, namely a live vaccine, an inactivated vaccine and / or a recombinant vaccine, through corresponding construction and manufacturing method procedures so as to prevent COVID-19 pandemic.

The invention discloses a bovine A-type foot-and-mouth disease broad-spectrum multi-epitope recombinant vaccine, and a preparation method and an application thereof, and belongs to the field of veterinary vaccine research. The preparation method comprises the following steps: carrying out reasonable serial connection on the major antigen epitopes of pandemic in China and bovine A-type foot-and-mouth disease virus representative strains recently pandemic in countries bordering China by adopting a brand new reverse vaccinology idea and strategy, coupling with a bovine IgG heavy chain constant region, cloning into a prokaryotic expression vector to construct a recombinant expression vector, transforming Escherichia coli cells to express a recombinant antigen, purifying by adopting Ni-NAT column chromatography, quantifying by a Bio-Rad protein quantification kit, and preparing the vaccine individually or combining with a recombinant foot-and-mouth disease virus 3D protein. A result of animal immune experiments shows that the multi-epitope antigen or 3D protein combined vaccine can stimulate the body to produce a protective antibody with high titer and also can protect immune animals against a virus attack, so the bovine A-type foot-and-mouth disease broad-spectrum multi-epitope recombinant vaccine has a good application prospect.

The present invention provides a composition for treating and / or preventing influenza, a method and an application thereof. The composition contains protein treated with acid anhydride and another drug for treating and / or preventing influenza. The acid anhydride-treated protein prepared by the invention is acid anhydride-treated lactoglobulin. An in vitro experiment shows that the protein can broadly inhibit influenza virus infected cells of various subtypes. In animal in vivo experiments, the protein has a significant prevention and treatment effect on influenza virus infection. Influenza viruses have many subtypes and high mutation rates, so that the development of broad-spectrum anti-influenza preparations is very important. The acid anhydride-treated protein can not only inhibits the infection of many seasonal influenza viruses, but also significantly inhibits the highly pathogenic avian influenza virus H7N9, and the influenza virus H1N1 (2009) which caused a pandemic, suggesting that the protein can be developed as a highly effective and broad-spectrum biological preparation for the prevention and treatment of influenza viruses.

With respect to pandemics, restaurants, stadiums, cafeterias, and bars are among the most dangerous places to socialize due to the form of interaction. Exchange of bacteria and viruses are facilitated intensively from the mouth and nose via air transport in droplets of saliva and bodily fluids being deposited on surfaces, foods, and in the air. The present development creates a comfortable environment where the air-space of each customer is separated by invisible cold-hot air and vis-UV barriers, which take away bacteria and viruses, destroying them and preventing recirculation while offering pleasant, clean, and sanitized ambient conditions for a face to face meeting. An immersive experience can be provided with surrounding screens and gas therapy that may be customized according to the customer's preferences. Food distribution is performed with a robotic shuttle system and when the customer departs, an extensive cleanup is performed using chemicals and UV irradiation through robotic systems.

Unlike the existing powered air-purifying respirators (PAPR) that are bulky, heavy, and expensive the invention offers a light-weighted inexpensive portable PAPR consisted of a single piece secured on user's head. The respirator is for use in contaminated environment including one with highly contagious viruses such as SARS-CoV-2 that causes COVID-19. A clear visor of the respirator protects eyes, nose, and mouth. The rest of the user's head protected with a soft airtight cover. A small fan or fans pump air through the filters. Because the fan capacity exceeds airflow required for breathing, air pressure under the cover is slightly higher than ambient pressure. It protects the visor and user glasses from fogging and prevents leaks through any looseness. A special port allows use of equipment and devices as a stethoscope for medics or oxygen supply for patients. Despite the respirator primarily targeted for medical personnel and patients, its convenience, l lightness and affordability allow usage by general population especially at the time of an epidemic or a pandemic.
