    Area of Science:

    • Immunology
    • Microbiology
    • Vaccinology

    Background:

    • Nonspecific defense reactions, termed paramunity, are crucial for overall immunity.
    • Intestinal defense mechanisms protect against enteric pathogens and viruses.
    • Interferon plays a role in antiviral and antibacterial responses.

    Purpose of the Study:

    • To experimentally demonstrate the importance of an oral polybacterial vaccine.
    • To evaluate the vaccine's role in local intestinal defense.
    • To discuss the involvement of interferon in immune responses.

    Main Methods:

    • Administration of an oral polybacterial vaccine.
    • Experimental challenge with Salmonella and an enterovirus.
    • Assessment of local intestinal defense mechanisms.

    Main Results:

    • The oral polybacterial vaccine significantly enhanced local intestinal defense.
    • The vaccine conferred protection against both Salmonella and enterovirus challenges.
    • Evidence supports the role of paramunity in vaccine-induced protection.

    Conclusions:

    • Oral polybacterial vaccines are effective in bolstering intestinal immunity.
    • Paramunity is a key factor in the efficacy of nonspecific defense.
    • Interferon likely contributes to the protective effects of the vaccine.
