If the Delta variant of the coronavirus is indeed so strong that vaccinated people can spread it relatively easily, it is important not to hold festivals for the time being, “no large groups close together, so no nightclubs and no events,” says Frits Rosendaal. , professor of epidemiology at the Leiden University Medical Center.
Vaccines reduce the chance that someone will become seriously ill after being infected or die from the corona virus. But if the number of infections rises, the number of deaths can also rise slightly.
That is why, according to Rosendaal, it is important to continue to vaccinate to protect people. “Contagiousness is a big problem for countries with a low vaccination coverage. That’s why you also have to vaccinate in poor countries, otherwise the virus will continue to mutate.”
