VACCINES & PROPHYLAXIS
The flu is a highly contagious and common illness that is caused by the influenza virus. People of all ages can get the flu. However, children, the elderly, and people with weakened immune systems are most susceptible and more likely to develop serious complications.
Out of the four different types of Influenza virus, type A & B accounts for most of the serious cases and outbreaks that occur worldwide.
Pneumonia is an infection in your lungs that inflames the air sacs, sometimes filling them with fluid or pus. Pneumonia affects millions of people every year, particularly children under age 5 and adults over age 65, as well as people who are hospitalized or who have chronic illnesses or immunosuppression.
Bacterial pneumonia is the most common type of pneumonia. It often occurs secondary to an infection that weakens your immune system, like the flu, but can also occur without a preceding infection.
