The mucosa forms special immunological memory—a breakthrough for vaccine research
If a vaccine is to protect the intestines and other mucous membranes in the body, it also needs to be given through the mucosa, for example as a nasal spray or a liquid that is drunk. The mucosa forms a unique immunological antibody memory that does not occur if the vaccine is given by injection. This has been shown by a new study from Sahlgrenska Academy, Sweden, published in the prestigious Nature Communications.Immunological memory is the secret to human protection against various diseases and the success of vaccines. It allows our immune system to quickly recognize and neutralize
