Fully vaccinated people can still catch COVID-19, but getting the vaccine dramatically lowers the risk percentage. The chief scientist of the World Health Organization said the vaccine injections had protected most people from serious illness or death from COVID-19.

“Reports indicate that vaccinated populations have cases of infection, particularly with the delta variant. The majority of these are mild or asymptomatic infections, ”said Dr Soumya Swaminathan, chief scientist of the World Health Organization, on Monday.

She added that hospitalizations are increasing in parts of the world where the Delta variant is spreading, but mainly in areas with low vaccination coverage. In the United States, almost all of the recent severe cases of COVID-19 resulting in hospitalization and death have been in unvaccinated people. Breakthrough infections in fully vaccinated people are rare, according to the Center for Disease Control and Prevention.

However, the WHO chief scientist has warned that vaccinated people can still contract the disease and also transmit the virus to others. The body urged people to continue to adhere to the mask and social distancing protocol.

Commenting on this, WHO Director-General Tedros Adhanom Ghebreyesus said: “The delta variant is tearing apart around the world at a breakneck rate, resulting in a new spike in cases and deaths. However, not all suffer the same blow. We are in the midst of a growing two-way pandemic where the haves and have-nots within and between countries increasingly divide in places with high immunization coverage. “

Recent studies suggest that people who are fully vaccinated, when infected with COVID-19, shed significantly less virus than those who are not vaccinated. According to WHO officials, more studies are needed to judge the impact of vaccination on transmissibility.
