【Thankful Promotion】GSK Zoster Vaccine 2 doses (Service deadline: 30 November 2025)

“ZOSTER” is caused by the varicella-zoster virus which stays latent in the cells of the dorsal root ganglia after primary inflection (chickenpox) and upon reactivation. Therefore, people who had had chickenpox before are prone to zoster. Areas, where nerves connect with skin, are also vulnerable to zoster. 95% of adults are at risk for zoster because they have been exposed to chickenpox. Zoster can stay up to 30 days, the pain caused is greater than what you expect.

The severity of zoster varies among different people, acute pain is the most common symptom of zoster but many people describe the pain caused by zoster as acute, intense, and throbbing. Even if the rash subsided, you still feel unwell. Even a soft touch can also appear unusual sensitivity.
