Influenza Virus
Evolution
Influenza A persistent public health
challenge .
Naturally vaccines were used to attack Influenza virus.
But the problem was not over yet
Due to
The rapid evolution of influenza viruses.
Has led for marginal vaccine efficacy.
As the influenza virus evolves marginal vaccine
Efficacy remains .
,Anti viral resistance and annual emergence
Of novel strains .
This evolvability is driven in part by the
Virus's capacity to generate diversity through
mutation and reassortment .
This requires new vaccines to suit against
Newer strain
Ultimate result is survival of the fittest.
Mutations play an important role
In influenza virus evaluation.
