Three new studies by US Centers for Disease Control and Prevention (CDC) showed that, who are not vaccinated against the novel coronavirus disease are 10 times more likely to die from the infection compared to those who have taken the shots.
The incidence of SARS-CoV-2 infection, hospitalization, and death is higher in unvaccinated than vaccinated persons, and the incidence rate ratios are related to vaccine effectiveness as per CDC.
Findings were consistent with a potential decline in vaccine protection against confirmed SARS-CoV-2 infection and continued strong protection against COVID-19–associated hospitalization and death.
Getting vaccinated protects against severe illness from COVID-19, including the Delta variant, and monitoring COVID-19 incidence by vaccination status might provide early signals of changes in vaccine-related protection that can be confirmed through well-controlled vaccine effectiveness (VE) studies, study said.

The studies appeared in the agency’s Morbidity and Mortality Weekly Report.
Higher hospitalization and death rates are observed in older age groups, regardless of vaccination status.
Vaccine effectiveness in preventing Covid-related hospitalisation dropped to 80 per cent among adults aged above 65 years compared with 95 per cent among those aged between 18 and 64 years.
