By April 30, 2021, the CDC reported approximately 101 million fully vaccinated individuals in the United States. According to the data, among this fully vaccinated cohort, only 10,262 cases of reinfection with coronavirus have been officially reported. Thus, the CDC report showed that the chance of contracting coronavirus after vaccination is 0.01%.
About a quarter of infections are classified as asymptomatic. A total of 995 of the infections resulted in hospitalization, of which only 160 deaths were recorded. The median age of patients who died was 82, and nearly 20% of deaths were reported as potentially unrelated to COVID-19.
The CDC notes that the total number of infections after vaccination may be underestimated. The US National Surveillance System relies on passive and voluntary reporting, and data may be incomplete or representative. Many people who are infected after vaccination, especially those who are asymptomatic or who have mild illness, may not be tested.
The Centers for Disease Control and Prevention (CDC) is a federal agency of the US Department of Health, established in 1946. Its role is in health and safety by providing information to improve health care solutions.
