A significant amount of the hospitalizations and deaths associated
with an initial influenza infections are due to secondary pneumonias
that develop during the course or an individual attempting to fight
the flu. One way to protect against a common cause of secondary
pneumonia, Streptococcus pneumoniae is with a the PPSV23 a pneumonia
vaccine. It specifically protects against Sthe bacteria Streptococcus
pneumoniae. The only companies that I am aware of that market this
particular type of vaccine is the US is Wyeth and Merck. Apparantly
cases are increasing and public health officials are urging that at a
minimum high risk individuals be vaccinated.

As the article attached reads "All children under 5 should receive the
pneumococcal conjugate vaccine and people at high risk of pnemonia
between the ages of 2 and 64 and those older than 65 should receive
another pneumonia vaccine known as PPSV23, CDC officials said."
Children already get at birth so can subtract them out but all the
other high risk individuals would constiture millions of doses of
vaccine. Also, would suspect that if the cases of pneumonia increase
that there will be many more who develop pnemonia who were otherwise
considered not to be at risk, so there is the potential for greater
demand for the vaccine by others as well, not to mention global demand
in countries where they do not curretly immunize against Streptococcus
pneumoniae.
This vaccine is not cheap so would be impactful on revenue.

Streptoccocus pneumoniae is not the on culprit that can cause
secondary pneumonias.  Haemophilus influenzae, Staphylococcus aureus
and group A Streptococcus, which causes rheumatic fever and "strep
throat" can also all cause it. But, most people get vaccinated
against  Haemophilus influenzae as kids. There isn't a vaccine for
Staphlococcus aureus or Group A Strep. they're both reated with
antibiotics.
