COVID-19: From Pandemic to Endemic – Why Staying Vigilant Matters
Six years after the onset of the COVID-19 pandemic and three years into the endemic phase, public attention and concern have significantly waned. Although, the World Health Organization (WHO) continues to emphasize the ongoing risks posed by COVID-19 and recommends sustained efforts to increase vaccination rates, particularly among high-risk groups.
The Evolving Threat of COVID-19
While the risk of COVID-19 infection has decreased compared to the peak of the pandemic, the virus continues to mutate and has established itself as a recurring seasonal illness, similar to influenza. This ongoing presence leads to a continuous stream of cases.
Data from the Disease Management and Prevention Agency’s hospital-level surveillance shows that in 2023, 8,632 patients were hospitalized with COVID-19, ranking it as the third most common acute respiratory infection, following rhinovirus (13,535) and influenza virus (11,773).
Protecting Vulnerable Populations
COVID-19 remains a significant threat to high-risk groups, including the elderly and individuals with underlying health conditions, increasing their risk of hospitalization and death. Older adults experience immune senescence, leading to diminished immune function and chronic systemic inflammation, hindering their ability to clear the virus effectively.
Individuals with pre-existing conditions like hypertension and diabetes similarly face a substantially increased risk of severe outcomes from COVID-19 infection. The virus’s continuous evolution and the waning immunity from vaccines further underscore the require for ongoing protection.
The Importance of Updated Vaccination
Vaccination remains a crucial preventative measure, even for those previously vaccinated. Annual vaccination with the latest vaccine formulations, designed to target current variants, is recommended.
Recognizing this ongoing need, governments are integrating COVID-19 vaccination into national immunization programs. Starting with the 2025-2026 season, individuals aged 65 and older, those with compromised immune systems, and residents of long-term care facilities will receive free COVID-19 vaccines.
Those eligible for vaccination during the winter respiratory season can receive a free vaccine until April of the current year. Unlike influenza, which primarily circulates during the winter months, COVID-19 has demonstrated the ability to spread year-round, making continued vigilance essential.
New Vaccine Technology: Prefilled Syringes
The latest COVID-19 vaccine, Comirnaty, from Pfizer, is now available in a prefilled syringe format. This simplifies the administration process, reducing the potential for errors and saving time for healthcare professionals. Previously, vaccines were supplied in vials requiring manual preparation.
This new format offers increased convenience for both healthcare providers and patients, streamlining the vaccination process.
Expert Perspectives on Continued Protection
“For individuals 65 years and older, those with weakened immune systems, and other high-risk groups, the risk of severe illness from COVID-19 remains substantial, making vaccination a vital preventative measure,” says Kim Tae-hyung, Professor of Infectious Diseases at Soonchunhyang University Seoul Hospital. “This proves crucial that these individuals complete their vaccination as soon as possible.”
Professor Kim also emphasizes that, “While many may perceive COVID-19 as a disease of the past, respiratory infections are unpredictable. Continued preparedness and a proactive approach are essential, even with relatively low current infection rates. A shift in public perception and increased vaccination rates are necessary.”
Frequently Asked Questions
- Is COVID-19 still a threat? Yes, COVID-19 continues to circulate and mutate, posing a risk, especially to vulnerable populations.
- Who should obtain vaccinated? Individuals aged 65 and older, those with weakened immune systems, and residents of long-term care facilities are strongly recommended to get vaccinated.
- When is the best time to get vaccinated? While fall/winter is common, vaccination is beneficial year-round due to the virus’s continued circulation.
- What type of vaccine is available? Comirnaty, a Pfizer vaccine, is now available in a convenient prefilled syringe format.
Pro Tip: Don’t wait for a surge in cases to get vaccinated. Proactive protection is the best defense against severe illness.
