Safety Profile

Adverse Events: Serious side effects remain rare, with most reactions mild (fever, fatigue, injection-site pain).
Long-term Data: Evidence shows sustained safety, though more research is needed for children, cancer patients, and immunocompromised groups.

WHO Guidance (2026)

Routine Vaccination: Recommended for high-risk groups (elderly, immunocompromised, healthcare workers).
Coadministration: COVID-19 vaccines can be safely given alongside influenza and other routine immunizations.
Future Research: Focus on durability of protection, variant-specific boosters, and equity in global distribution.

Risks and Trade-offs

Breakthrough Infections: Vaccinated individuals may still contract COVID-19, especially with immune-evading variants.
Waning Immunity: Protection decreases over time, making boosters essential.
