Flu Vaccination Campaign Expanded to Protect Vulnerable Populations

As respiratory virus cases rise and a new variant of the H3N2 influenza strain circulates, health officials are urging individuals in high-risk groups to get vaccinated against the flu. Vaccination is now readily available and free of charge for key populations, including healthcare workers, seniors, young children, and those with underlying health conditions.

Who Should Get Vaccinated?

The current flu vaccination campaign prioritizes several groups due to their increased vulnerability to severe illness:

• Adults 65 Years and Older: This age group is at significantly higher risk of developing serious flu complications, including hospitalization, and death. Between 70% and 85% of seasonal flu-related deaths occur in people 65 years and older . They do not require a medical order to receive the vaccine.
• Children 6 Months to 2 Years Old: Young children are particularly susceptible to influenza and its complications.
• Individuals with Risk Factors: People with chronic medical conditions such as COPD, chronic kidney failure, diabetes, transplant recipients, and those undergoing cancer treatment are also strongly encouraged to get vaccinated. A medical order is required to verify these conditions.
• Healthcare Personnel: Frontline healthcare workers are at high risk of exposure and transmission of the flu, making vaccination crucial for protecting both themselves and their patients.

Vaccine Recommendations for Seniors

The Centers for Disease Control and Prevention (CDC) and the Advisory Committee on Immunization Practices (ACIP) recommend that individuals 65 years and older receive a higher dose flu vaccine – either a high-dose inactivated vaccine, a recombinant vaccine, or an adjuvanted inactivated vaccine – over standard-dose options. These vaccines are designed to create a stronger immune response in older adults, whose immune systems may be weakened .

Current Influenza Landscape

Globally, seasonal influenza activity has been increasing, with a notable rise in influenza A(H3N2) viruses. A new subclade, A(H3N2) J.2.4.1 (alias K), has been detected in several countries, exhibiting genetic changes from related strains . Even as current data doesn’t indicate increased disease severity, this evolution highlights the importance of vaccination. Early estimates suggest the influenza vaccine continues to provide protection against hospitalization, even with the emergence of new strains .

Accessing the Vaccine

Flu vaccine doses are available at health centers and hospitals throughout the province. Individuals with reduced mobility or disabilities can request a home visit from a nurse by contacting their local health center. For those residing in nursing homes or elderly care facilities, vaccination will be administered on-site by healthcare personnel.

Increased Risk in Older Adults

Adults aged 65 years and older are at increased risk of severe influenza-related symptoms and complications due to both chronic comorbidities and a natural decline in immune function (immunosenescence) .

Key Takeaways

• Flu vaccination is crucial for protecting vulnerable populations from severe illness and complications.
• Individuals 65 years and older should consider receiving a higher-dose flu vaccine for optimal protection.
• The current influenza landscape includes a new H3N2 subclade, emphasizing the importance of vaccination.
• Vaccines are readily available and free of charge for prioritized groups.
