"Since the outbreak of COVID-19, scientists have been exploring the development
of mucosal vaccines that can be delivered through the nasal route. Recently,
researchers in Berlin have successfully created a live attenuated vaccine for
the nose. In a recent study, they detail the unique immune response it elicits.
The spread of coronaviruses primarily occurs through the air when infected
individuals expel droplets of saliva containing the virus through speaking,
coughing, sneezing, or laughing. These airborne pathogens are then inhaled by
others, leading to infection. In an effort to combat the virus that causes
COVID-19, a research team in Berlin has decided to target the initial point of
entry, the mucous membranes of the nose, mouth, throat, and lungs.
To do so, the scientists developed a live attenuated SARS-CoV-2 vaccine that is
administered through the nose. In the latest issue of the journal
Nature
Microbiology, the interdisciplinary team describes how this live attenuated
vaccine confers better immunity than vaccines injected into muscle.
Already in the fall of last year, two nasal vaccination formulations were
approved for use in India and China. These contain modified adenoviruses –
which typically cause respiratory or gastrointestinal illnesses – that are
self-attenuating, meaning they either replicate poorly or stop replicating
altogether, and therefore never trigger disease. Other live nasal vaccines are
currently undergoing development and testing around the world."

could let people immune-compromised go out without fear."
