Risk Factors for Shingles 

Almost 1 in 3 Canadians will experience shingles in their lifetime. The risk and severity of shingles increase significantly after age 50. Older adults and individuals with weakened immune systems are more likely to develop shingles and its complications. 

While anyone who has had chickenpox can get shingles, it is more common in those over 50 or in people with compromised immune systems due to conditions like cancer, HIV/AIDS, or certain medications. 

Shingles and Asthma 

Chronic respiratory diseases, including asthma, can increase the risk of developing shingles and its complications. Individuals with asthma may have a higher likelihood of experiencing shingles, especially if they are using inhaled corticosteroids, which can weaken the immune system. 

Shingles can lead to serious complications, including postherpetic neuralgia (PHN), which is a type of nerve pain that persists after the rash has healed. For people living with asthma, managing both conditions effectively is essential to minimize complications. 

Vaccination against shingles is particularly important for individuals with asthma, as it helps protect against both the infection and its potential complications. 

Why Get Vaccinated for Shingles? 

Vaccination is the best way to protect yourself from shingles. Although you can still get shingles after receiving the varicella vaccine, vaccinated individuals are 4 to 12 times less likely to develop shingles compared to those who are unvaccinated. The vaccine is recommended for most people aged 60 and older. 

How Does the Shingles Vaccine Work? 

The Shingrix vaccine, the primary vaccine available in Canada, contains a protein called glycoprotein E (gE) from the varicella zoster virus. When vaccinated, your immune system recognizes this protein and produces antibodies to help protect against shingles. 

Available Shingles Vaccine in Canada 

The Shingrix® vaccine (Recombinant Zoster Vaccine, RZV) is the only shingles vaccine available in Canada. It is given as two doses, with the second dose administered 2 to 6 months after the first. Shingrix is safe and effective at reducing the incidence of shingles and postherpetic neuralgia (PHN), a type of nerve pain that can occur after shingles. 

Recommendations for Vaccination: 

• Recommended for individuals 50 years and older without contraindications. 

• Those who have previously received the live-attenuated zoster vaccine (LZV) or had shingles should get RZV at least one year later. 

• Immunocompromised adults 50 years and older may be considered for RZV on a case-by-case basis. 

Some individuals should not receive the vaccine, such as those with specific allergies or those taking certain medications. Always consult with a healthcare provider to determine the best options for you.
