📋 Summary:
Respiratory Syncytial Virus (RSV) is a leading cause of severe respiratory illness in infants and older adults. We provide two high-quality, licensed vaccines — Abrysvo (Pfizer) and Arexvy (GSK). Abrysvo is the only option for pregnant individuals to protect their newborns. Both vaccines are available for older adults and high-risk individuals. Contact our clinical team to determine the best option for you or your family.
Respiratory Syncytial Virus (RSV) is a common and highly contagious virus that infects the respiratory tract. While most healthy adults experience mild cold-like symptoms, RSV can cause severe lower respiratory tract disease (LRTD) — including pneumonia and bronchiolitis — in infants, older adults, and individuals with underlying health conditions.
Vaccination is a safe and effective way to protect against severe RSV disease. At our clinic, we offer two lcensed RSV vaccines manufactured by Pfizer and GSK. Both are approved by the Hong Kong Department of Health and are available for eligible individuals.
💡 Our Commitment:
We offer both Abrysvo and Arexvy to give patients choice. Our clinical team follows the latest guidelines and Hong Kong's immunisation standards to ensure safe, effective vaccination for every eligible individual.

Frequently Asked Questions
Q: What is the difference between Abrysvo and Arexvy?
Abrysvo (Pfizer) is a bivalent recombinant vaccine that targets both RSV A and B subtypes[reference:32]. It is licensed for pregnant individuals (32–36 weeks), adults 60+, and adults 18–59 at increased risk. Arexvy (GSK) is an adjuvanted recombinant vaccine that contains a substance to boost immune response. It is licensed for adults 60+ and adults 50–59 at increased risk, but not for use in pregnancy.
Q: Which RSV vaccine should I choose?
For pregnant individuals (32–36 weeks), only Abrysvo is licensed. For adults 60 and older, both are options — Abrysvo is a bivalent vaccine without adjuvant, while Arexvy contains an adjuvant to enhance immune response. For adults at increased risk, Abrysvo is approved for 18-59 years old, Arexvy is approved for 50-59 years old. Discuss with our clinical team for personalised advice.
