The next leap in coronavirus vaccine development could be a nasal spray
Washington PostAPR 2022
Every development of a new, better vaccine is a step in the right direction. Three years into the pandemic, COVID is here to stay, which is why broader solutions like Blue Lake's are the way forward — chasing perpetual variants with targeted vaccines is no longer a viable option.
Broader solutions are certainly the goal, but nasal vaccines likely won't meet this. Immunity that comes from infection similarly enters the body through the respiratory tract but only offers a brief period of protection from infection, so nasal sprays would probably have the same impact. The antibodies created by nasal vaccines typically wane quicker than others.
