Soberana 02 is a combined vaccine in which the antigen of the virus, the receptor binding domain (RBD), is chemically linked to the tetanus toxoid.
According to Verez, the vaccine has two formulations and the second one achieved great effectiveness in animals, since it provoked a very powerful immune response from the first week of its first dose.
It also induces a long lasting memory in the immune response that, besides producing antibodies, makes them last.
Therefore, that formula is having a different expectation and it would only be necessary to confirm those results in humans, the scientist said
SOBERANA 01, is a two-dose vaccine based on an RBD amino-acid sequence that by design allows natural dimerization of two RBD molecules. This is combined with outer membrane vesicles of meningococcus B that act as an immunopotentiator. In short, the goal is to induce production of neutralizing antibodies against SARS-CoV-2.
