In the early stage of the COVID-19 epidemic, the infection rate among children was relatively low. However, with the global pandemic of COVID-19 infection, overseas data show that the infection rate of children and adolescents is constantly rising. Under the spreading threat posed by mutant virus strains, children and adolescents who are yet to receive vaccination should get vaccinated as early as possible for self-protection. Vaccination is crucial to protect children and adolescents against COVID-19 disease to effectively decrease the rates of serious illness and death. Vaccination enables adolescents to resume normal school and daily life as soon as possible.
Since 16 February 2022, Comirnaty(BioNTech) vaccine has been made available to children and adolescents aged 5 and above, this age group can also choose to receive CoronaVac(Sinovac).
From 4 August 2022 onwards, children and adolescents aged 6 months to 17 years can receive Sinovac vaccine. From 16 February 2022 onwards, they can also receive BioNTech vaccine according to the recommendation of the Joint Scientific Committees joined by the Chief Executive’s expert advisory panel (JSC-EAP).
Starting from 4 August 2022, the minimum age for receiving the CoronaVac vaccine (Sinovac vaccine) will be lowered to 6 months starting. Having regard to the advice of the Advisory Panel on COVID-19 Vaccines, and considering the risks posed by the COVID-19 epidemic to the local community, as well as the benefits of lowering the eligibility of receiving the Sinovac vaccine to cover children aged 6 months to 17 outweigh the risks, the Secretary for Food and Health has earlier approved the eligibility of receiving the Sinovac vaccine to cover individuals aged three and above.

How many doses of COVID-19 vaccination do children and adolescents need?
Hong Kong currently provides two types of COVID-19 vaccines, primary immunization as three doses:
Sinovac vaccine (aged 6 months -17 years): Two doses at 28 days intervals (First two doses at 28 days intervals; second and third dose at 90 days intervals.)
BioNTech vaccine (aged 5 to 17): Two doses at 12 weeks intervals. Emerging data suggest that two doses of the Comirnaty vaccine with a longer interval would result in better immune response, and the risk of myocarditis and/or pericarditis would be lowered. For adolescents with special needs (e.g. study aboard) who choose to advance the second dose to after 21 days from their first dose, they need to bring along a signed parent consent form and must be accompanied by their parent or guardian in person.
Children and Adolescents receiving BioNTech will be arranged for thigh injection. They can wear loose-fitting, easy to roll-up or other suitable clothing for ease of vaccination.
Besides, experts recommend a third dose of COVID-19 vaccine for certain individuals such as immunocompromised patients^. The third dose can be given at least 28 days after the second dose.
For details of the specific group of immunocompromised patients, please refer to the government's thematic website FAQ 34 (https://www.covidvaccine.gov.hk/en/faq).
Are there any differences in the COVID-19 vaccine for adolescents and adults?
Answer: Yes, there is no difference in the ingredients and they are essentially identical.
However, for BioNTech, the dosage for children aged 5 to 11 years is one-third of a dose for adults.
Is the vaccine safe for children and adolescents?
SinoVac: There are trials (Phase I and II) on the use of the Sinovac vaccine in children and adolescents aged 6 months to 17 years that showed that the Sinovac vaccine is immunogenic, safe and well-tolerated. The ongoing phase II trials also showed that the Sinovac vaccine was well-tolerated in this age group.
Information from mass vaccination campaigns in Mainland China indicated that among aged 3 to 17 years old has not shown major safety issues. (over 210 million doses of Sinovac vaccine administered)
The vaccine has high efficacy against symptomatic COVID-19 disease. Vaccination is crucial to protect adolescents again symptomatic COVID-19 disease.
