Vaccines are powerful shields, training our immune system to fight. But no shield is perfect—it’s possible to get sick after vaccination, often with milder symptoms. Understanding this helps us stay informed and safe.
Booster shots are follow-up vaccine doses designed to refresh our immune defenses. They strengthen protection against diseases, helping us stay one step ahead of evolving viruses and keeping communities healthier.
Vaccines spark our immune system’s memory, but sometimes that memory fades. Boosters serve as gentle reminders, reigniting protection to keep us safe from evolving germs and prolonged threats.
World Immunization Week shines a light on vaccines, celebrating their power to protect millions. It exists to remind us that immunization saves lives, strengthens communities, and builds a healthier future for all.
