Why Do Breakthrough Infections Happen?

Vaccines are designed to train the immune system to recognize and fight the virus quickly. However, no vaccine offers 100% protection. Several factors contribute to breakthrough infections:

• Virus Variants: New variants of the virus may partially evade immune protection.
• Waning Immunity: Protection can decrease over time, especially without booster doses.
• Individual Differences: Age, underlying health conditions, and immune system strength all influence how well a vaccine works.
