Vaccinated people are just as contagious as unvaccinated a lot of media headlines recently on the basis of a study published in the renowned Lancet appeared. There is only one thing that can be said about this study.
The biggest problem is that the studied group of unvaccinated people consisted of only 23 people, mainly children. And children are much less contagious anyway. “If you want to measure the effectiveness of vaccines against infectiousness in 50-year-olds, you should not take an unvaccinated control group of under or around the age of 18,” says epidemiologist Brechje de Gier (RIVM), who discovered the statistical error. in the Volkskrant. “We also initially found no difference between vaccinated and unvaccinated. But when we split it up by age, we did see an effect of vaccination in our analysis.”
How big the difference is in the spread between vaccinated and unvaccinated. According to de Volkskrant, the latest figures show that vaccines 50 to 90 percent of infections, 95 percent of hospital admissions and 97 percent of ICU admissions. The chance that an infected vaccinated person will infect someone else is about half the chance that an unvaccinated person will pass on the virus, research by De Gier showed.
