Yes. i believe i covered this in my first post on the topic. Covaxin is an inactivated viral vaccine. They take longer to develop, as the entire virus given to the human body takes longer study. Hence it came out much later, despite coming from the largest vaccine producer's market. Same with Sinopharm one. different types of vaccines have their pros and cons. As with different types of tech for the same outcome. The main attraction of the IVC types is that it sees far less efficacy drop over time ( again, the reason is obvious) and is cheaper to transport. The main drawback is, it takes longer to produce, has lower overall efficacy and slightly higher risk of vaccine injury.
The main advantage of the mRNA is that it is quickest to develop and hit the market and a higher initial efficacy. The main drawback is, it drops off efficacy the worst over time, while being the most expensive to transport. The attenuated viral vector vaccine ( sputnik, AZ) sit between these two in terms of development cycle time and transportation cost, their efficacy rate has too big a spread ( AZ is at low 70s percent initially, Sputnik is at low 90s) to effectively classify it relative to the other two tech types. These are the pros and cons of the various types in a nutshell. Hence i think we should approve more, with a greater flexibility for the canadians to take it in the future - as if this becomes an epidemic and not a pandemic ( ie, not iradicated completely), then the question of vaccine for people not born yet becomes the next factor to consider.
