>>13519879Here's a shitty answer, because a very well rafted answer would take too long.
The influenza genome is made up of multiple strands of DNA, each carrying part of the genome.
The coronavirus is a single strand of DNA, which contains all its genes.
It's easier for multiple strains of influenza to develop because of reassortment, and the strains have a wider range of variation. Coronavirus cant do reassortment.
Because different viruses work in different ways, an appropriate response to one is not an appropriate response to another. In this case, a coronavirus booster may be adequate, even if it isnt delta specific. Whereas an influenza booster may be worthless
