Any competent virologist will tell you that if you want to reduce the risk of infection of a respiratory virus, increasing the level of mucosal IgA antibodies is required. And you want to increase the receptor binding domain (RBD) antibodies especially because these antibodies prevent the virus from attaching to the entry point receptors (ACE2) on your cells.
So any vaccine that reduces your risk of infection has to increase the secretory IgA antibodies that target the RBD on the virus.
That’s right. This paper clearly and unambiguously showed that the COVID “vaccines” make you more susceptible to getting COVID, not less. It’s a disaster. And it was as clear as night vs. day 2.5 years ago when this paper came out. If anyone was paying attention that is.
It should have led to the CDC warning people that they lied to people about reducing the risk of infection. They should have warned the public that getting the COVID vaccine will increase your risk of getting COVID.
