Some recent studies have claimed that vaccinated people have a similar high viral load to unvaccinated people who get COVID-19. In other words, vaccinated people were said to be as effective at transmitting the virus as unvaccinated people. These results did not fail to raise concerns about the efficacy of vaccines in preventing transmission.
However, these results apparently do not support claims that the vaccine does not actually play a role in preventing transmission. Because the virus load in vaccinated people is cleared faster than unvaccinated people. That is, they live for less time with a high viral load. From this, it turns out that, according to experts, the risk of vaccinated people transmitting COVID-19 is less.
In a study conducted on 471 people with COVID-19, it was revealed that there was no great difference in the ceiling virus load rates between vaccinated and unvaccinated individuals. In addition, it has been claimed that an individual has the same potential to transmit COVID-19 even if vaccinated, since the rates of transmission to people living in the same household are at the same levels. However, this analysis only considers the ceiling viral load. It does not show the amount of virus load distributed over time. The viral load indicates how long the COVID-19 virus has been circulating in a person’s bodily fluids. Vaccinated people are less likely to be infected than unvaccinated people, because the virus lives less in their bodies and clears more quickly. So, looking over time, it turns out that vaccinated individuals are less contagious. The same results apply to the more contagious Delta variant.
