WHO representative: We do not know date when vaccines will stop virus spread


January 19, Fineko/abc.az. Margaret Harris, a spokeswoman for the World Health Organization, has held a briefing today in connection with the vaccination in a range of countries.

ABC.AZ reports that according to the WHO spokeswoman, it would take several months for the vaccination to develop collective immunity.

She also noted that it is not yet known when vaccines will be able to prevent the spread of infections:

"Vaccines will help, but not immediately. The formation of mass immunity to the virus will take months. We also don't know when vaccines will stop the spread of the virus. We know that only vaccines will stop the disease."
