Abstract  

Interferon has broad-spectrum antiviral, immunomodulatory and antitumor effects. Recombinant human interferon α1b is the first class I genetic engineering new drug with independent intellectual property rights in China. After years of research, a variety of dosage forms such as recombinant human interferon α1b injections and sprays for children and adults have been developed. A series of pharmacological, toxicological, pharmacokinetic and clinical studies on interferon α1b for the treatment of pneumonia such as coronavirus have been completed, becoming clinical consensus and guidance documents. According to these results, interferon α aerosol inhalation was recommended as the first anti-viral treatment of novel coronavirus caused pneumonia in multi-version of "National diagnosis and treatment of novel coronavirus caused pneumonia" released by National Health Commission of the People's Republic of China, and achieved good medical effects. Recombinant human interferon α1b spray, as a drug that can prevent viral infections, is widely used in the biological protection of high-exposure populations such as medical personnel, which plays an important role in the prevention and control of the epidemic, and will make contributions to national health and biosafety.
