Abstract

The invention discloses an influenza new coronary combined vaccine. The influenza new coronary combined vaccine is prepared from the following raw materials in mass concentration: 1 to 100 micrograms/mL of recombinant new coronary vaccine containing RBD-Fc fusion protein, 1 to 50 micrograms/mL of influenza subunit vaccine containing H1N1 type influenza virus, 1 to 50 micrograms/mL of influenza subunit vaccine containing H3N2 type influenza virus, 1 to 50 micrograms/mL of influenza subunit vaccine containing B type influenza virus, an aluminum hydroxide solution and the balance of PBS phosphate buffer, wherein the final concentration of aluminum ions in the influenza new coronary combined vaccine is 0.5 to 2.0mg/mL. A preparation method comprises the following steps of: weighing all the raw materials; diluting the four vaccines with the PBS phosphate buffer respectively and then mixing with the aluminum hydroxide solution; and mixing according to an equal volume ratio to obtain the influenza new coronary combined vaccine. The influenza new coronary combined vaccine disclosed by the invention is a combined vaccine of a novel coronavirus vaccine containing an aluminum adjuvant and the influenza subunit vaccine containing the aluminum adjuvant; and after combination, the two antigen component vaccines are not mutually inhibited and can be very well compatible.

Description

technical field [0001] The invention relates to the technical field of biological products, and more specifically relates to a combined influenza and new crown vaccine and a preparation method thereof. Background technique [0002] COVID-19 spreads rapidly and has a high case fatality rate, and an effective vaccine is urgently needed to control the pandemic. [0003] As of December 2020, there are 60 vaccines based on six different technical routes, including inactivated vaccines, nucleic acid vaccines (including DNA vaccines and mRNA vaccines), vector vaccines, protein subunit vaccines, live attenuated vaccines, and virus-like particle vaccines. 3 candidate vaccines have been approved to enter clinical trials, and 7 vaccines (3 inactivated vaccines, 2 mRNA nucleic acid vaccines, and 2 vector vaccines) have been approved for emergency use or qualified for marketing. [0004] At present, a total of 18 new coronavirus protein subunit vaccines have entered clinical trials, acc...
