Researchers have developed an innovative method of administering vaccines without using needles: through the gum.
In a new proof-of-concept study, scientists successfully vaccinated mice against the flu using dental floss treated with inactive flu viruses.
Most vaccines are administered with a needle, and this method has its drawbacks. For example, fear of injection pain and needle phobia can cause people to refuse vaccination. Injections also require more complex medical skills than needle-free methods such as mouth drops or nasal sprays, and are more difficult to store and distribute.
