2015-2016 Influenza (Flu) Information

Influenza, often called “the flu,” is an upper respiratory infection (nose throat and lungs) caused by an influenza virus. It spreads easily from person to person through coughing, sneezing, or face-to face contact. People often use the term “flu” to describe other illnesses such as the "stomach flu" or the common cold which are different illnesses, caused by other pathogens. 

Influenza symptoms can include fever, headache, muscle pain, runny nose, sore throat, extreme tiredness, and cough. Children may also experience nausea, vomiting, or diarrhea. Although these symptoms are similar to the common cold, symptoms caused by influenza tend to be more severe and last longer (7-10 days).

Influenza is not always a harmless illness. It can cause serious health risks including death. A person with influenza is also at risk of other infections, such as bacterial or viral pneumonia (an infection of the lungs). Every year, about 1,400 people in B.C. die from influenza and complications of influenza, such as pneumonia. The peak of the influenza season is traditionally November to April. Your best protection from getting and transmitting influenza is the influenza vaccine.

During the influenza season, residents who are at risk are advised to get their free influenza vaccine. Influenza vaccine (available through your local health unit, pharmacist, and your family doctor), along with good personal hygiene, including effective hand washing, provides the best defense against contracting and spreading the influenza virus. If you do find yourself sick with influenza, you can help protect others from getting ill by observing safe cough etiquette, staying home and resting, drinking plenty of fluids and managing your symptoms.

About the vaccine:

The 2015/16 seasonal trivalent influenza vaccines contain the following strains:

  • A/California/7/2009 (H1N1)pdm09-like virus
  • A/Switzerland/9715293/2013(H3N2)-like virus
  • B/Phuket/3073/2013-like virus
  • B/Brisbane/60/2008-like virus(quadrivalent vaccines only)

The A/Switzerland/9715293/2013 and B/Phuket/3073/2013 strains were not contained in the 2014/15 season vaccine; the B/Brisbane/60/2008-like strain was contained in the quadrivalent but not trivalent vaccines in the 2014/15 season.


Beginning the week of November 2, 2015, seasonal influenza vaccine will be available at Public Health clinics.  It is free of charge for the following groups of people:

  • People 65 years and older and their caregivers/household contacts 
  • People of any age in residential care facilities 
  • Children and adults with chronic health conditions and their household contacts 
  • Children & adolescents (6 months to 18 years) with conditions treated for long periods of time with  Acetylsalicylic Acid (ASA) and their household contacts. 
  • Children & adults who are morbidly obese (adult BMI>40; child BMI assessed as >95th percentile adjusted for age and sex). 
  • Aboriginal people (on and off reserve). 
  • All healthy children 6-59 months of age. 
  • Household contacts and caregivers of infants and children 0-59 months of age. 
  • Pregnant women at any stage of pregnancy during the influenza season and their household contacts . 
  • Inmates of provincial correctional institutions. 
  • People who work with live poultry. 
  • Health care and other care providers in facilities and community settings who are capable of transmitting influenza disease to those at high risk of influenza complications. 
  • Visitors to health care facilities and other patient care locations. 
  • Individuals who provide care or service in potential outbreak settings housing high risk persons (e.g., crew on ships). 
  • People who provide essential community services (first responders, corrections officers). 
  • Visitors to health care facilities and other patient care locations. 

Pneumococcal vaccine is also available to high-risk individuals (seniors and those with chronic medical conditions) to prevent pneumococcal disease- one of the most common complications of seasonal influenza.  Unlike influenza vaccine, pneumococcal vaccine is generally given only one time with a one-time booster for those at higher risk. Please ask your health care provider if you also need this vaccine; if required, influenza and pneumococcal vaccines can be given at the same time.
