Seasonal Influenza Vaccination Program Begins September 26: Public Urged to Get Vaccinated

2024/25 Seasonal Influenza Vaccination Programmes to start on September 26

The Centre for Health Protection (CHP) of the Department of Health (DH) today (September 19) announced that the 2024/25 Seasonal Influenza Vaccination Programmes, including the Seasonal Influenza Vaccination School Outreach Programme and the Residential Care Home Vaccination Programme (RVP), will begin on September 26. The CHP urged the public to receive the seasonal influenza vaccination (SIV) to better protect themselves during the coming influenza season.

The local winter influenza season usually starts in January, while the summer surge occurs from July to August. For the influenza season which started in mid-January 2024, it ended in late July, lasting for 28 weeks. The predominant virus was initially influenza A (H3), which later shifted to A (H1) as the season progressed. The CHP believes that this prolonged influenza season was due to changes in the circulating influenza virus strains.

According to the latest surveillance data on the percentage of respiratory specimens testing positive for seasonal influenza viruses and the influenza-related admission rate in public hospitals, local seasonal influenza activity currently remains at a low level. However, with the weather expected to become cooler, the CHP expects that local seasonal influenza activity will increase by the end of this year.

"SIV is one of the most effective means to prevent seasonal influenza and its complications. All persons aged 6 months or above, except those with known contraindications, are recommended to receive the SIV for personal protection," a CHP spokesperson said.

In the 2023/24 season, about 1 870 000 doses of seasonal influenza vaccines, an increase of about 20 per cent compared with the 2022/23 season, were administered under various programmes. The number of doses administered was a historical high with the concerted efforts of all stakeholders and parties.

Seasonal Influenza Vaccination Programmes

Under the Seasonal Influenza Vaccination Programmes for the 2024/25 season, the eligibility criteria for receiving free or subsidised SIV remain largely the same as in the previous season (Annex I). Eligible members of the public can receive free SIV at the following public venues. The recommended vaccination venues are as follows:

- General persons: Vaccination by family doctors or District Health Centres

- Persons with chronic illness: Vaccination by public or private clinics providing regular follow-ups

-General children: Vaccination through the Seasonal Influenza Vaccination School Outreach Programme or by family doctors

-Children with chronic illness: Vaccination by public or private clinics providing regular follow-ups

To make vaccinations more accessible this year, the Government will introduce additional vaccination venues, including the DH's MCHCs for all children aged 6 months to under 2 years, and 16 District Health Centres/District Health Centre Expresses, providing more choices for the public. For a list of vaccination venues, please refer to the CHP's Vaccination Schemes page.

Starting from 9am on September 23, parents of children aged 6 months to under 2 years may book an appointment for their children to receive vaccinations at designated MCHCs via the online booking system: https://booking.covidvaccine.gov.hk/forms/sivfhs/index_en.jsp.

Over 1 600 doctors have enrolled in the Vaccination Subsidy Scheme (VSS). The Government will provide a subsidy of $260 per dose of vaccination. Over half of the enrolled VSS doctors will not charge extra in addition to the Government's subsidy. For the list of VSS doctors, please visit: https://apps.hcv.gov.hk/Public/en/SPS/Search.

Seasonal Influenza Vaccination School Outreach Programme

Under the Seasonal Influenza Vaccination School Outreach Programme, secondary schools, primary schools, kindergartens, and child-care centres can arrange outreach vaccination teams to provide SIVs to schoolchildren. Schools may choose to join the Seasonal Influenza Vaccination School Outreach Programme (SIVSOP) and/or the Vaccination Subsidy Scheme (VSS) School Outreach Programme. Under SIVSOP, the DH will arrange vaccination teams to provide free SIV for participating schoolchildren. The vaccines will be provided by the DH, and a subsidy of $105 per dose will be given to doctors.

Schools may also arrange outreach vaccinations under the VSS School Outreach Programme by selecting a doctor and making arrangements for the outreach activity, including the type of vaccine to be provided. The Government will provide a subsidy of $260 per dose to the doctor. In addition to schoolchildren, other individuals such as school staff and students' parents can also receive SIVs during the outreach vaccination activity.

To improve vaccine coverage among schoolchildren, the SIVSOP has implemented the following special arrangements for the 2024/25 season:

Currently, around 860 kindergartens and child-care centres (79 per cent), 610 primary schools (92 per cent), and 380 secondary schools (75 per cent) have arranged vaccination activities for their schoolchildren. Based on local experience, participation in outreach vaccination programmes can significantly increase the influenza vaccination rate among schoolchildren by more than double, reaching an average vaccination rate of 70 per cent, effectively strengthening the immunity barrier among schoolchildren. The Government encourages schools that have not yet enrolled to sign up for the outreach vaccination programme as soon as possible.

Residential Care Home Vaccination Programme

Under the Residential Care Home Vaccination Programme, the DH will deliver vaccines for free to care homes. Visiting medical officers enrolled in the programme are invited by institutions to provide vaccination services to eligible residents. The subsidy will be $105 per dose. Residents and staff of residential care homes for the elderly and persons with disabilities, non-institutionalised persons with intellectual disabilities (PID) receiving services, staff working in designated institutions serving PID, and residents and staff of residential child-care centres can receive vaccination services from outreach teams starting from September 26.

The Scientific Committee on Vaccine Preventable Diseases (SCVPD) under the CHP has recommended that the composition of vaccines for the 2024/25 influenza season should align with the World Health Organization's latest recommendations. For details on the trivalent or quadrivalent influenza vaccines to be used in the 2024/25 northern hemisphere influenza season, please refer to the SCVPD's recommendations.

Both IIVs and LAIV are recommended for use in Hong Kong by the SCVPD. Depending on the brand, most IIVs are recommended for use in people aged 6 months or older, including healthy individuals, pregnant women, and those with chronic medical conditions. LAIV can be used for people aged 2 to 49 (except those who are pregnant, immunocompromised, or have other contraindications).

The public, especially those in the eligible groups, may call the CHP's enquiry hotline (2125 2125) during office hours or visit the CHP's Vaccination Schemes page for more information on the above vaccination schemes.

CHP reminds public on precautions against cold weather

The Centre for Health Protection (CHP) of the Department of Health (DH) today (December 22) reminded the public, particularly the elderly and people with chronic illnesses, to adopt appropriate measures to protect their health in view of the cold weather.

A spokesman for the CHP said that cold weather can easily trigger or exacerbate diseases, especially among the elderly and persons suffering from heart disease, respiratory illnesses or other chronic illnesses.

"Elderly people have less insulating fat beneath their skin to keep them warm, and their body temperature control mechanisms may be weaker. Their body may not be able to appropriately respond to thecold weather," the spokesman said.

Some senior persons may have decreased mobility, which can impair their ability to generate and conserve body heat. Chronic illnesses, such as hypertension, diabetes and endocrine disorders, may undermine the health of elderly people and lower their metabolic rate, subsequently causing their body to generate less heat. Persons with chronic illnesses, such as chronic respiratory illnesses or heart disease, are vulnerable to disease aggravation due to cold weather.

The CHP reminded the public, in particular the elderly and persons with chronic illnesses, to adopt the following preventive measures:

Take note of the weather forecast. Wear warm clothing, including hats, scarves, gloves and socks, accordingly;

Consume sufficient food to ensure adequate calorie intake;

Perform regular exercise to facilitate blood circulation and heat production;

Stay in a warm environment and avoid prolonged outdoor exposure;

Use heaters with care and maintain adequate indoor ventilation; and

Seek medical advice if feeling unwell.

​In addition, the public should avoid alcoholic beverages.

"Drinking alcohol cannot keep you warm. Alcohol accelerates the loss of body heat through dilated blood vessels, resulting in chilling instead," the spokesman said.

"Parents should ensure that babies are sufficiently warm, but it is also important to keep babies relatively lightly clothed to avoid overheating them," the spokesman added.

Parents should observe the following safety measures when putting their children to bed:

Keep the room well ventilated and at a comfortable temperature;

Always place babies on their backs to sleep. Leave their heads, faces and arms uncovered during sleep;

Babies do not need pillows. Place babies on a firm and well-fitted mattress to sleep. Avoid soft objects, pillows and loose bedding;

Let babies sleep in a cot placed near their parents' bed; and

Maintain a smoke-free environment.

In addition, many respiratory pathogens, including influenza and SARS-CoV-2, may have increasing activity and community transmission during winter. Seasonal influenza vaccination is recommended for all persons aged 6 months or above, except those with known contraindications. Persons at higher risk of getting influenza and its complications, including the elderly and children, should receive seasonal influenza vaccinations early. Please see details of the vaccination schemes on theCHP's website.

A person who gets influenza and COVID-19 at the same time may be more seriously ill and would have a higher risk of death. It is important for elderly persons, especially those residing in residential care homes, to receive both a seasonal influenza vaccination and a COVID-19 vaccination. They should also receive an additional booster against COVID-19 according to recommendations as soon as possible. The public should also maintain good personal and environmental hygiene against respiratory illnesses and note the following:

Surgical masks can prevent transmission of respiratory viruses from ill persons. It is essential for persons who are symptomatic (even if having mild symptoms) to wear a surgical mask;

Wear a surgical mask when taking public transport or staying in crowded places. It is important to wear a mask properly, including performing hand hygiene before wearing and after removing a mask;

Avoid touching one's eyes, mouth and nose;

Wash hands with liquid soap and water properly whenever possibly contaminated;

When hands are not visibly soiled, clean them with 70 to 80 per cent alcohol-based handrub;

Cover the mouth and nose with tissue paper when sneezing or coughing. Dispose of soiled tissue paper properly into a lidded rubbish bin and wash hands thoroughly afterwards;

Maintain good indoor ventilation;

When having respiratory symptoms, wear a surgical mask, refrain from work or attending classes at school, avoid going to crowded places and seek medical advice promptly; and

Maintain a balanced diet, exercise regularly, take adequate rest, do not smoke and avoid overstress.

Food-borne diseases, particularly those linked to hotpot cuisine, are also common in cold weather. The following preventive measures should be taken:

Wash hands before handling and consuming food;

Do not patronise unlicensed vendors or those with poor hygienic standards while selecting food;

Wash and cook all food thoroughly;

Vegetables should be washed thoroughly in clean running water before cooking and consumption. When appropriate, scrub vegetables with hard surfaces with a clean brush to remove dirt and substances, including pesticide residues and contaminants, from surfaces and crevices;

Shrimps should be fully cooked until the shells turn red and the flesh turns white and opaque;

For shellfish such as scallops and geoduck, scrub the shells thoroughly and remove internal organs;

Do not eat any undercooked freshwater aquatic products. To ensure that the food is thoroughly cooked, the centre of the food should reach a temperature of at least 75 degrees Celsius so as to destroy pathogen;

Most hotpot ingredients should be stored in a refrigerator at 4 degrees C or below, while frozen food should be stored in a freezer at -18 degrees C or below;

Never use raw eggs as a dipping sauce for hotpot; and

Use different sets of chopsticks to handle raw and cooked food to avoid cross-contamination.

​In addition, when using fuel-burning appliances, especially in indoor areas, the public should ensure adequate ventilation to avoid harmful exposure to carbon monoxide (CO) and prevent CO poisoning.
