Hello, Everybody! If you have been diagnosed with Chronic Bronchitis, Emphysema or COPD you will be wise to get a Pneumonia Vaccine and a Influenza Vaccine! It would be very dangerous not to! I just read an article in Huffington Post that says - Don't combine any Vaccine with your Flu shot! So get them separately but get them! A pneumonia shot is good for about 5 years and a flu shot is for only one season - the trick is when to get vaccinated! My doctor recommended that I get mine sometime between Halloween and Thanksgiving. Ask your doctor if you have any questions. Take care and have a safe winter!
