In the development of vaccines, people are mostly worried about the occurrence of ADE (antibody dependence enhancement).
If ADE occurs, it means that after some people are vaccinated, their own immune response will cause the disease to worsen.
An expert from the Shanghai Public Health Clinical Center recently revealed to a reporter from China Business News: “Our latest research has found that the novel coronavirus’ ADE phenomenon does exist, and the proportion is not low. The relevant research results are waiting to be released.” However, he did not yet know whether the results will be published in a peer-reviewed journal.
According to Dr. Li-Meng Yan, having an effective vaccine for the CCP-virus might be hard to achieve due to ADE phenomenon.

CCP-Virus Reinfection & Immunity
The first documented COVID 19 reinfection has been reported in Hong Kong verified by genetic sequencing.
Dr. Seheult of https://www.medcram.com explains the importance of this patient’s symptoms (he was asymptomatic with the second infection) and how immunity to viruses typically builds over time with subsequent exposures or vaccines.
Dr. Seheult also discusses comparisons to previous viruses such as smallpox that have caused large numbers of deaths among populations without any prior exposure.
