Delta Variant Rise and Decreased Immunity Fuel Breakthrough Infections

As reported by The Washington Post : “A growing number of studies suggest that coronavirus vaccines continue to provide strong protection against severe disease and hospitalization, but their ability to prevent mild illness is less robust today than the original clinical trial studies demonstrated a year ago. The virus has mutated. The delta variant is rampant. Some elements of immunity may be gradually waning for people who got shots many months ago. New research studies in the United States, Israel, Britain and Qatar have shown a partial erosion in the effectiveness of vaccines against mild to moderate infections. Immunocompromised people are winding up hospitalized despite being vaccinated.”
