![]() ![]() Mucosal vaccines are different from traditional vaccine types because they enter through our mucus membranes, either in the mucosa that lines our nose (as in the much-discussed nasal COVID-19 vaccine) in our gut (as in an orally suspended vaccine, like QYNDRs) or in the lining of our respiratory tract, such as China's inhalable booster vaccine from CanSino Biologics which was authorized in China in September. However, they'll need a body of evidence behind them, which requires attention and money.Ī vaccine you swallow, and ones you can inhale Scientists hope mucosal vaccines will not only protect against severe disease and death, like the revolutionary mRNA vaccines and boosters have proven to do time and time again, but ward off infections as well. ![]() This means that for most people, a positive COVID-19 test result doesn't mean the same thing today as it did in August 2020 or winter 2021. Some treatments, including the antiviral Paxlovid, are still available for preventing people at high risk of getting really sick, from getting really sick. Vaccines and booster doses remain available and protective against severe disease for those willing to take them. But if they outcompete on the infection front, they could be the new generation of COVID-19 vaccination.ĬOVID-19 is still here and deadly - though it's causing far less damage (roughly 400 deaths per day) compared to the peak in January 2021, when thousands were dying per day according to data from the US Centers for Disease Control and Prevention. But researchers are still waiting on data to confirm whether mucosal vaccines "deliver" on their promise to stop infections. But around the world, researchers are nudging their way in with new names and new vaccine forms, like the nasal or inhaled vaccines that have recently been rolled out in China and India. When we talk about COVID-19 vaccines, we tend to talk about the same big names: Pfizer, Moderna, Johnson & Johnson, AstraZeneca. Algi Febri Sugita/SOPA Images/LightRocket via Getty Images
