Since the COVID-19 pandemic in early 2020, a total of 9,000 COVID deaths and more than 1 million infections have been recorded in Hong Kong over two years. To combat pandemics, the government has coordinated pandemic countermeasure strategies. Recent studies have shown that different restrictions and measures have raised different opinions among the general public, some of which have made a difference in residents’ compliance with COVID prevention measures and their intentions to vaccinate.

The Hong Kong Polytechnic University (PolyU), with the support of the Food Health Department’s Health Medicine Research Fund, traverses to investigate Hong Kong residents’ compliance with various COVID precautions and their willingness to receive vaccines. We conducted a targeted survey. The study, which randomly sampled 1,225 people aged 18-85, consisted of a three-stage telephone interview between the 4th and 5th waves of the pandemic in Hong Kong.The survey results are published at International Journal of Environmental Research and Public Health When vaccination Each.Researchers have revealed that they tended to “rise and then fall.” vaccination Hesitating among the respondents. The team suggested that the government should further review its vaccination incentives and adopt two approaches (through policy and education) to raise people’s awareness and confidence in vaccines.

Stage 1 (December 19, 2020-January 6, 2021)

The first round of telephone interviews took place at the beginning of the fourth wave of the pandemic, where the public vaccination program had not yet begun. The majority of the 1,225 respondents reported compliance with the government’s proposed precautions, but also showed their reluctance to vaccinate with the COVID vaccine.

  • Wear a face mask in public (94%)
  • Avoid touching eyes, nose and mouth (88%)
  • Use alcohol-based hand sanitizers (82%) to maintain social distance (75%)
  • Show willingness to vaccinate (42%)
  • Indicates hesitation or refusal to vaccinate (58%)

Your intent to get vaccinated is influenced by multiple factors. High motivation to vaccinate means male gender, age, type of employment, past epidemic experiences such as SARS and swine flu, reduced concern about vaccine safety, awareness of risk of infection, self-efficacy It may be related to the improvement of the flu and the improvement of the acceptability.Disease prevention measures

Stage 2 (June 1, 2021-July 11, 2021)

Six months after the first interview, 1,003 respondents were contacted to track actual vaccination status. In this second round of interviews, three months after the start of the COVID-19 vaccination program (Note: the program officially started on February 26, 2021), one in four respondents. People (24%) reported having received at least one vaccination of the COVID-19 vaccine. The main reasons given are:

  • Ensuring personal health (68%) and family health (64%)
  • Meet workplace vaccination requirements (55%)
  • Answer government calls (42%)
  • Prepare for unquarantined travel and unrestricted social activities (28%)

The findings showed that the actual vaccination status was not related to the pre-vaccination intent. Instead, respondents’ vaccination decisions were influenced by confidence in the government and health system, acceptance of pandemic measures, current experience with COVID-19, and the vaccination status of those they know. ..

Stage 3 (December 21, 2021-January 21, 2022)

The third round of the interview took place early in the fifth wave of the pandemic, 12 months after the first round and almost a year after the start of the COVID-19 vaccination program. At that time, more than 80% of respondents had been vaccinated with the COVID vaccine at least once. The main reasons given are:

  • Meet workplace vaccination requirements (57%)
  • Ensuring personal health (55%) and family health (51%)
  • Respond to government calls (32%)
  • Travel without quarantine and preparation for unrestricted social activities (32%)

Changes in vaccination intent

The survey results are from the respondents intention Vaccinations have changed over time. The increased vaccine hesitation and rejection rate declined in the third round of the interview.

  • Stage 1: Vaccine hesitation or refusal (54%), Vaccine motivation (46%)
  • Stage 2: Vaccine hesitation or refusal (58%), vaccine motivation (42%), at least one dose of vaccine (24%)
  • Stage 3: Vaccine hesitation or refusal (42%), vaccine motivation (59%), at least one dose of vaccine (80%)

“The intention to vaccinate is related to the intensity of the pandemic wave and the severity of the pandemic countermeasures,” said Elsie Chau-wai Yan, Associate Head of the PolyU School of Applied Social Sciences, who leads the study. .. “For example, during the less serious fourth wave of the pandemic, residents were reluctant to receive jabs, but Omicron-led infections began to dominate Hong Kong and the government began implementing vaccination requirements. When both the intent of vaccination and the actual vaccination rate increased to higher levels. “

To further promote vaccination, the government should adopt a flexible strategy to encourage people to get vaccinated, Yang suggests. “It is important to develop timely pandemic measures and introduce compulsory vaccination into specific populations, but it is just as important for the government to step up the promotion of vaccination. A thorough description of the benefits and needs of individuals and their families can be the key to success. ”
