What is Shingles?

Shingles is a viral infection caused by the same virus that causes chickenpox, known as the varicella-zoster virus. After a person recovers from chickenpox, the virus remains dormant in the nervous system and can reactivate later in life as shingles. It typically causes a painful rash, often in a band-like pattern on one side of the body, and is accompanied by itching, burning, or tingling sensations.

Shingles is more common in older adults and those with weakened immune systems, though anyone who has had chickenpox can develop it. The pain from shingles can sometimes persist even after the rash heals, a condition known as postherpetic neuralgia.

Shingles can occur anywhere in the world, but its prevalence tends to be higher in certain populations, particularly in older adults and individuals with weakened immune systems. The infection is common even in devolving countries such as the uk, especially as our population ages.

Overall, shingles is most prevalent in older adults, with the risk increasing significantly after the age of 50, and it affects both men and women equally. The availability of vaccines has also helped reduce the incidence in countries with widespread vaccination programs.

How to prevent Shingles?

Shingles can be prevented by vaccination, marinating a healthy immune system and avoiding contact with infected people. Vaccination is the most effective preventive measure, the vaccination is recommended for anyone over 50 even if they have had shingles or chickenpox in the past. The vaccination (typically shingrex) requires two doses and is typically given 2 to 6 months apart. Another type of vaccination, Zostavax, does exist but it is being used less as it is less effective in comparison to shingrex.  Maintaining a healthy immune system is also a good prevention method, patients should be aware of existing medical conditions they have, especially if they weaken the immune system as this puts them at higher risk of developing the infection as the immune system will have a harder time fighting it off. Having a balanced diet, getting a lot of exercise and adequate sleep will all help prevent the infection.

Are there side effects of the shingles vaccine?

The shingles vaccination is generally safe. However like most vaccinations there are some side effects. Common side effects include; Headaches, muscle pain, fatigue and redness at the injection site. Some rarer side effects are allergic reactions, which happens if you are allergic to any component of the vaccine and GBS which is when a person’s immune system attacks the peripheral nerves, this is rare and the vast majority of people recover even from the most severe cases. It is also important to realise that the benefits of vaccination far outweigh the risks.

If you experience these or any other side effects after taking the vaccine you should report it to your GP even if you are not certain that the vaccine caused it.
