“What If a Covid-19 Vaccine Is Never Developed?” by the Inforgraphics Show, June 18.
Actually, it should say “never found to be effective”.
There are reasons to throw cold water on the vaccine hopes. We never have developed an effective vaccine against a coronavirus, and this video reports that the antibodies produced by an original SARS virus were not very effective. NBC News has a more balanced and detailed story on this attempt, which lost funding.
Also, with short term antibodies, the risk of ADE, or antibody dependent enhancement, might exist with a vaccine, as what caused a catastrophe with a dengue vaccine in the Philippines (NPR story. Rachel Martin). (The NBC story above mentions that this problem happened with the SARS vaccine).
The video says that it is possible that effective anti-virals and PrEP, like what was developed for AIDS and homosexual men, might be more likely.
Otherwise, society would have to settle down to a “new normal” with rolling lockdowns and quarantines when infection rates reached a certain level.
It becomes much harder for people to leave their communities of origin and branch out and create their own lives, and society becomes more authoritarian and locally communitarian when there are serious public health problems. That is one reason for the intensity of the tribalism being seen today (as with the Black Lives Matter movement. It also provides an ideological reason for activists recruiting people into identarianism and intersectionality as the only way to save the space and rights for minority groups – they much accept the integrity of their own groups as such.
Vox reports on Dr. Fauci's confidence level (reasonable) in a vaccine by the end if 2020, even if this breaks world records for vaccine development by 400%.
