Intranasal vaccination

Intranasal administration of the vaccine is a method of delivering antibodies to the nasal mucosa, which provides a protective effect against respiratory tract infections. This method is used to prevent diseases such as influenza and coronavirus infection. Intranasal vaccination can be carried out with different vaccines against different infectious diseases, depending on the conditions and purposes of vaccination. Through intravaginal injection, antibodies are delivered directly to the tissue of the nasal mucosa and stimulate the body's immune system to produce protective responses, and then easily spread to other parts of the body. This vaccination method provides long-term protection against many pathogens. Intranasal vaccination is especially useful in areas with high infection rates
