In Hong Kong, where seasonal flu outbreaks are a recurring concern, understanding flu vaccines is crucial for maintaining public health. At OT&P clinic, you can access a range of flu vaccines, including the “Fluarix Tetra”, “Influvac Tetra ”, and “Vaxigrip Tetra” options, all classified as inactivated influenza vaccines (IIV). We will also be prescribing intranasal flu vaccines (administered as nasal spray or mist) classified as live attenuated influenza vaccines (LAIV), a pain-free option for children, which will be available soon. This blog post will explore their effectiveness, the recommended vaccination groups, and essential considerations for individuals in Hong Kong who are considering flu vaccination.
According to the World Health Organization (WHO), influenza activity has been reported globally, with influenza A viruses being the most common. Specifically, A(H1N1) and A(H3N2) strains have been prevalent. In Hong Kong, the 2023-2024 winter influenza season saw a notable increase in cases starting from the second week of January, with a peak in early February. Although the activity decreased slightly in late February, it remained elevated in early March.
OT&P currently offers Fluarix Tetra vaccines, Influvac Tetra vaccines, and Vaxigrip Tetra vaccines:
The Scientific Committee on Vaccine Preventable Diseases (SCVPD) recommends the following for the 2024-2025 season:
The flu vaccine helps protect against the four influenza viruses that research indicates are most common during the upcoming season. It can help prevent you from getting sick with the flu. If you get sick, getting the vaccine reduces the severity of illness and lowers the risk of flu-associated hospitalisation. A 2021 study showed that among vaccinated patients who were admitted to the hospital with influenza, 26% had lower risk of intensive care admissions and 31% had low risk of death from flu compared to the unvaccinated.
The flu shot is a beneficial preventive tool for people with chronic health conditions. Even if you are healthy, getting the vaccine is an important way of protecting yourself and your loved ones who may be more vulnerable. During pregnancy, it helps protect pregnant women and after pregnancy it confers protection to the infants from flu in their first few months of life.
As we enter the peak of seasonal influenza, the risk of transmission will get higher and appropriate prevention is important. The Centers for Disease Control and Prevention (CDC) recommends that in the absence of contraindications, all persons aged 6 months and above should receive the influenza vaccine annually.
