I really want to see a vaccine appear soon, since it’s our only hope for ending this pandemic in the long run. I’m also realistic and know that it would be really unusual to develop one this quickly. AstraZeneca is testing one, and already the trial is on hold, after bad but unspecified adverse effects appeared in the test population.
This is not surprising, and it’s to be expected that the development will not be smooth and linear. It’s still disappointing.
Next, of course, we don’t even know how effective the vaccine will be. You shouldn’t have been partying yet anyhow.
