The Novavax vaccine uses a version of the spike protein made in the lab. The spike proteins are assembled into tiny particles called "nanoparticles" which aim to resemble the structure of the coronavirus, however they cannot replicate once injected and the vaccine cannot cause you to get COVID-19.
In order for these subunit vaccines to generate strong protective responses, they need to include molecules that boost your immune system, called "adjuvants." The goal of these adjuvants is to mimic the way the real virus would activate the immune system, to generate maximum protective immunity.
Novavax includes an adjuvant based on a natural product known as saponin, an extract from the bark of the Chilean soapbark tree.
Plant-based foods are rich in phytochemicals that cannot be found in meat and dairy. Saponins, for instance, occur naturally in soybeans, peas, horse chestnut, yams, quinoa and grains. These plant steroids have the ability to foam when mixed with water and boast various health benefits. They exhibit anti-inflammatory and immune-boosting properties as well as antibacterial effects. Their name comes from the Latin word "sapo," which means soap.
You're a dumb fuck. Use your brain and think about why they are actually stopping these vaccines.
Look at which vaccine they happen to be allowing.
meanwhile Novavax, which is just the spike protein is no closer to approval.
