4-valent Influenza Vaccine

HKD $400

Safe and effective

Introduction

Fall and winter are coming and so is the Flu season. People might think getting flu shots after receiving COVID-19 jabs is unnecessary, but this is not the case. Anyone, including normal and healthy adults, can experience severe sequelae from the flu. Emerging evidence suggests that co-infection with COVID-19 and influenza viruses can increase severe clinical implications and mortality rates. In contrast, influenza vaccination can reduce the likelihood of hospitalization and shorten hospital stays. Therefore, the public should get vaccinated as soon as possible before the peak flu season, especially the elderly, children and pregnant women. It is recommended that the public be vaccinated with a new season of flu shots in October or November every year to obtain adequate protection before the flu season begins. According to the latest guidelines from the government, members of the public are encouraged to receive the COVID-19 vaccine and seasonal flu vaccine simultaneously (including inactivated influenza vaccines, live attenuated influenza vaccines and recombinant influenza vaccine).

Prevention

The WHO recommends that quadrivalent vaccines for use in the 2023-2024 northern hemisphere influenza season contain the following:

Egg-based vaccines
an A/Victoria/4897/2022 (H1N1)pdm09-like virus;
an A/Darwin/9/2021 (H3N2)-like virus; and
a B/Austria/1359417/2021 (B/Victoria lineage)-like virus; and
a B/Phuket/3073/2013 (B/Yamagata lineage)-like virus.

Cell culture- or recombinant-based vaccines
an A/Wisconsin/67/2022 (H1N1)pdm09-like virus;
an A/Darwin/6/2021 (H3N2)-like virus;
a B/Austria/1359417/2021 (B/Victoria lineage)-like virus; and
a B/Phuket/3073/2013 (B/Yamagata lineage)-like virus.

Details

Why should I get the flu shot?

Influenza vaccination is one of the effective means of preventing influenza and its complications together with a reduction in influenza-associated hospitalisation and death.

When should I get the flu shot?

The most effective period to receive seasonal influenza vaccination is between October and November every year, or at least two weeks before the flu peak season arrives, to ensure the body develops sufficient antibodies.

What is the recommended dosage for the flu shot?

Persons aged 9 years or above: Single dose per year.

Children below 9 years of age: For those who have not received the influenza vaccine, 2 doses with an interval of at least 4 weeks and single for each year after.

What are the common side effects of the flu shot?

The most common adverse events following administration are local reactions, including pain, redness and swelling at the injection site.
Non-specific systemic symptoms including fever, chills, malaise and myalgia are uncommon and reported in less than 1%.

Do I need to get vaccinated for influenza every year?

Yes. The strains of influenza viruses change from year to year and the acquired immunity declines over time. We should receive the flu shot every year as recommended by the World Health Organization.
