Nose Spray Vaccines Could Quash COVID Virus Variants

This is a news story from The Scientific American by Marla Broadfoot. With the effectiveness of vaccines waning due to new variants coming about, scientists have been coming up with new ways to combat the virus. Scientists are thinking of developing a nose spray vaccine that attacks the virus at the source. It is believed that a vaccine delivered this method could trigger mucosal immunity. Nasal vaccines have been shown in the past to be more effective than traditional administration of vaccines. There is risk in this, however, because there still needs to be more research done on mucosal immunity. The advantage is that this vaccine does not rely on syringes or needles, so it has the possibility of reaching more people.
