Capvaxive was licensed based mostly on what is called immunogenicity testing, during which immune responses of people that acquired it had been in comparison with these of people that acquired a competitor vaccine. Separate trials had been carried out on individuals who had beforehand been vaccinated towards pneumococcal illness, and individuals who had not.
The corporate mentioned it is going to conduct a scientific trial to find out real-world effectiveness of the vaccine.
