Flu Vaccines

摘要

Winter is almost upon us and with it comes the usual influx of customers with colds and flu. Influenza or the ‘flu’ is not a disease to be taken lightly. Symptoms of flu range from mild and nonspecific upper respiratory tract infections to severe disease with complications such as pneumonia, respiratory failure, secondary bacterial infections and worsening of chronic conditions like asthma and congestive heart failure. Deaths from influenza are reported every year. Our best defense against flu is an annual influenza vaccine.
