Breakthrough Covid cases: How big is the risk?
July 22, 2021 - Most hospitalisations and deaths from coronavirus have occurred among unvaccinated people, yet there have also been so-called breakthrough infections of fully vaccinated people.
With Covid-19 shots reaching billions of people, reports have grown more common of people being infected with the coronavirus despite being vaccinated. Just as a natural infection does not guarantee protection from reinfection with the virus, neither does immunisation provide a perfect shield, according to Bloomberg.
Still, those who have immunity – either from vaccination or infection – carry a fraction of the risk of those who have none. Breakthrough cases among the immunised are a reminder that as long as the pandemic virus is prevalent in the world, it remains a threat to everyone, Bloomberg said.
