The death of 84-year-old former U.S. Secretary of State Colin Powell, who was fully vaccinated, has highlighted how older, immunized adults are still at risk for severe COVID-19 breakthrough infections.The U.S.
Centers for Disease Control and Prevention has said that vaccine breakthrough cases are expected as no vaccine is 100% effective.
But health officials maintain that the COVID-19 vaccine is still the best protection against serious illness and death from a coronavirus infection.
According to the AARP, older adults are already susceptible to COVID-19 complications due to underlying health conditions, which affect about 80% of older Americans.
