If you have received the New Crown vaccine, you will have a vaccination card with all the information about the New Crown vaccine that you received, and you can check the vaccine you received. The staff will print the information related to the vaccine on the vaccination record page directly after the vaccination, including the name of the vaccine, the manufacturer, the vaccine lot number, the expiration date, as well as the place, date and site of vaccination. If it is not convenient to inquire about the vaccination certificate, you can also do so through your cell phone. The inquiry system may vary from place to place, but generally inquiries can be made through the health code, which will show all the information about the vaccination of New Crown vaccine. With the outbreak of the New Crown epidemic, there is more and more research and development of New Crown vaccines worldwide, and the technical routes of New Crown vaccines now include inactivated vaccines, virus vector vaccines, subunit vaccines and nucleic acid vaccines. The safety and efficacy of vaccines that can be administered have definitely been confirmed, so there is no need to worry too much. Inactivated vaccines are vaccines made by a series of processes such as culturing, harvesting, concentration, inactivation and purification of pathogens, which are used earlier and show a high level of safety. Viral vector vaccines include adenovirus vectors, poxvirus vectors, and influenza virus vectors, which require only a single dose of vaccination and are more efficient, allowing the population to develop sufficient immunity relatively quickly. Recombinant subunit vaccines include different forms such as simple recombinant protein or nanoparticles. Nucleic acid vaccines include DNA vaccines, non-replicating mRNA vaccines and replicating mRNA vaccines. Regardless of the type of vaccine, they can currently be useful for the prevention and control of the new coronavirus. Actively responding to the call for vaccination can effectively reduce the rate of disease infection and, if infected, can also maximize control of the disease from progressing to severe disease.
