Are Flu Vaccinations a Good Route?

For children and people with compromised immune system, other illnesses, or generally unhealthy, Flu shots are probably a good idea, however, vaccination immunity is less vigorous and declines in effectiveness much faster than a natural immunity.  
Contracting a particular influenza virus imparts lifetime immunity, even to similar strains. For instance, during the 1918 pandemic, also known as the Spanish flu, many older adults likely had partial protection caused by exposure to the 1889–1890 flu pandemic, also known as the Russian flu. Even so, an immune compromised person could become susceptible though. 
Because vaccination responses are at low levels, immunity is less vigerous and they decline in effectiveness much faster than a natural immunity.
