The importance of flu shots and other vaccines

The influenza virus tends to be most active in North America between the months of October to March.  Approximately 3 to 11 percent of the population is affected every year.   

Flu symptoms usually come on very suddenly.  

Flu shots are recommended for everyone over 6 months of age, especially those at higher risk of severe illness. This includes those with weaker immune systems, cancer, heart or lung disorders, pregnant women, and those under age 2 or over 65. Babies younger than 6 months and people with a history of severe allergic reaction to the vaccine or one of its ingredients should not get the flu vaccine. It is now safe for those with an egg allergy to get any appropriate flu vaccine.   

There are two types of flu vaccines available: injectable and intranasal. There are some injectable vaccines made from inactivated influenza virus and some made without the virus. Some vaccines are only approved for adults, and the high-dose version is only for those who are at least 65 years old. You should discuss the best option for you with your pharmacist or primary care provider.  

In addition, other vaccines are available for certain adults for illnesses caused by RSV (respiratory syncytial virus), COVID-19, and pneumococcal infection, which can cause severe pneumonia. These infections can cause significant respiratory symptoms, leading to serious complications and even death in high-risk groups. Talk with your healthcare provider to see if you meet the criteria for these vaccinations.
