However, sequencing efforts did detect antibody-producing cells (B cells) that could produce potent neutralizing antibodies to SARS-CoV-2. The World Health Organization has specific criteria for when an epidemic becomes a pandemic. Passive immunity refers to the transfer of active humoral immunity of pre made antibodies. Strategies for Enhancement in Food Production. Passive immunity gives temporary protection by transfer of certain immune substances from resistant individuals. We acquire passive immunity by receiving antibodies that were not made by our own bodies. This passive immunity could eventually take place naturally, as soon as the maternal antibody is getting transferred to foetus by means of placenta.
