Note the long disclaimer, though, clarifying among many other things: "Possible Risks and Uncertain Benefits - Immediate allergic or other serious reaction - Unforeseen long-term effects - Instillation/administration of the vaccine in an inappropriate way or in an infected area might increase the risk of infection by enhancing viral entry into the body - Benefits are uncertain. There are extensive published histories of the materials and procedures described on this site, but every novel vaccine should be considered experimental, with the possibility there will be no benefit. - Even if there are signs of immune response there is no guarantee this response is indicative of protection from SARS-CoV-2 infection, or if protection is achieved, how long it will last. - Even if the vaccine confers protection from the virus, certain methods for assessing protection–such as measuring antibodies due to previous infection–might not capture vaccine-induced immunity. In such cases, infection, and thus a positive test result, are unlikely to occur. Immunity passports and other privileges given to convalescents might be difficult to obtain for those with vaccine-induced immunity. - Use of this vaccine may change the efficacy of any future vaccines you may take or that are administered to you, in unknown ways."
