In response to the looming threat of an immune deficit post-COVID-19 lockdown and the surge of influenza,Li-Zhi high school emphasizes the importance of flu vaccination and hygiene practices. Failure to get vaccinated increases susceptibility to infections, potentially leading to severe outcomes, including death. To confirm the health of our students and staff, we've implemented both paper and online sign-up options for flu vaccination. Partnering with the Health Bureau, our school hosted an on-campus vaccination event on November 1, 2023, with 281 doses administered, achieving an impressive student vaccination rate of 85.5%. This proactive approach effectively enhances individual and collective protection.
