The head of the Department of Immunology at the World Health Organization, Dr Catherine O’Brien, explained why some people are infected with the Corona virus, despite having received a vaccine against the virus.
Dr O’Brien said not all existing vaccines offer 100% protection against disease, but protection ranges from 80 to 90%, noting that the vaccines available against the virus work remarkably and effectively. .
She added that the severity of the virus infection and its complications are few in vaccinated cases, compared to people who have not been vaccinated, indicating that cases who contract the virus after receiving the vaccine are rare, such as the elderly, those with weak immune systems, and those who do not meet health requirements.
She stressed that vaccines work to protect those vaccinated against infection with the virus and protect others around them, calling on everyone to adhere to precautionary measures approved by relevant authorities in order to eliminate the virus and its variants.
