The founder of Microsoft bill gates said that a vaccine for the coronavirus may not be very effective as a barrier to the spread of infection. It is reported by CNN.
According to him, when creating vaccines, the scientists focused on two factors – prevention of diseases of the vaccinated person and prevention of transmission of coronavirus from him to other people.
