The head of the immunization department of the World Health Organization (WHO) Kate O’Brien called the shortcomings of vaccines against coronavirus. Her interview is available at Twitter of the organization.
O’Brien warned that precautions must be followed after vaccination, since the world community does not yet know if vaccination can protect a person from infection and transmission. Currently, only that drugs have been proven to protect against disease. According to her, this is a “very important” aspect of understanding the effectiveness of vaccines.
Another weakness of vaccines is that there is no evidence on how to administer vaccines for certain age groups, in particular for children. These categories of citizens will remain at risk of infection and transmission of infection to other people, the WHO representative said.
In addition, there is not enough vaccine in the world to protect everyone from the coronavirus, so you should continue to wear masks, keep your distance and wash your hands. Many countries are still facing a very widespread spread of the coronavirus, and the duration of the precautions depends on what countries can do to defeat the infection, O’Brien concluded.
Earlier, the WHO said it had no information that vaccination reduces the risk of transmission of coronavirus. “Since there is no evidence yet of the effect of the vaccine on the transmission of the virus, it is necessary to continue to adhere to non-pharmaceutical measures [to contain the virus], including wearing masks, physical distancing, washing hands, and so on,” the organization explained.
