Vaccination is the best protection against shingles and its complications. Shingles is a disease that appears only in people who have already had chickenpox. It is characterized by painful skin lesions, often in the form of blisters, on one part of the body.
Since May 1, 2023, the inactivated vaccine is free of charge to people aged 80 years and older as well as for people aged 18 years and older who are immunocompromised.
This vaccine is also recommended for people aged 50 to 79 years old, although it is not free for them.
The inactivated vaccine is made from pieces of the virus. It is 90% effective in preventing shingles. Its effectiveness is not reduced with age. However, if the disease develops in a person who has already been vaccinated, the risk of neuralgia, which is pain that lasts for several months after the lesions have disappeared, is reduced by 90%. The protection offered by this vaccine lasts at least 10 years after vaccination. Two doses, administered 2 to 12 months apart, are needed to ensure long-term protection.
Some symptoms may be caused by the vaccine, for example redness at the injection site. Other problems may occur by chance and are not related to the vaccine, for example a cold, gastroenteritis or a headache.
Shingles vaccine is safe.
Most reactions are benign and short-lived.
In 17% of cases, the reactions caused by the vaccine prevent the person from going about their daily activities for 1 to 2 days. These reactions, which are less common in older people, occur a little more frequently when the 2nd dose is given
