About the Novavax vaccine
The serum contains the spike protein of the SARS-CoV-2 virus, which causes COVID-19and an adjuvant, which is a substance that helps enhance the immune response to an antigen.
In these types of vaccines, when a person receives an injection, their immune system identifies the inactivated virus as “foreign” and produces antibodies against it, preparing them for future exposure to the coronavirus.
In the case of Novavax, the adjuvant Matrix-M was used, containing saponin extracts from the bark of the Soapbark tree native to Chile.
To evaluate the vaccine, a clinical trial was conducted in the United States and Mexico prior to the availability of the delta and omicron variants, in which the serum was shown to be effective in preventing COVID-19 90.4%.
Prior to Novavax, the US had already approved COVID-19 vaccines from Pfizer/BioNTec, Moderna, and Johnson & Johnson. (EFE)
