An mRNA vaccine is a nucleic acid vaccine capable of preventing viral infections.
The mRNA vaccine is mainly synthesized by synthesizing an antigen in vitro, which encodes a specific mRNA sequence, and injecting this viral mRNA into the human body as an antigen, which can activate the corresponding immune response in the body, enhance the body’s immunity to this kind of viruses, and achieve the purpose of preventing this kind of viral diseases. For example, it can prevent RNA viruses such as new coronavirus and DNA viruses such as cytomegalovirus.
The mRNA vaccine has the advantages of high safety and high immune efficiency. However, mRNA vaccines are also characterized by instability and easy degradation, so they need to be stored at lower temperatures and protected from light. Due to the strong immune response, some vaccinated patients may experience allergic reactions such as local tingling and skin itching. It is recommended that patients be vaccinated under the guidance of a doctor.
If serious discomfort occurs after vaccination, it is recommended to go to the hospital in time for treatment.
