2. Attenuated Vaccine
Attenuated vaccine is a live virus or bacteria with very low virulence administered. What they do is basically, they slowly replicate around themselves slowly. This vaccine requires less boosters because they tend to reproduce and continues to present antigen. However, there is a small chance of risk of reversion to virulence, which is smaller in vaccines with deletions. This type of vaccines can't also be used by those whose immunity is already compromised.
This type of vaccine sounds super cool to me but at the same time quite intimidating. What are your thoughts on it? Leave a comment and we shall discuss more about it!
Till then.
