It does not prevent the virus from spreading It does not protect against certain variations that we are seeing like in South Africa
This means that the pandemic will still be there next winter some how. Likely not as bad as it is now. But it won't be over yet as a thread for societies. Remember most emerging/developing countries are not expected to receive vaccinations any time soon.
They'll be able to update the vaccination but many people will lose trust in them unfortunately
Means that our economies & currencies will be in trouble
Remote work will break through. After 2 years nobody is used to anything else anymore
Many people will permanently lose their job/business, but software companies will continue to do extremely well (although there will be some regulatory crack down on the largest companies)
As I said, my contacts in the medical field have the same opinion as the article. It's "unknown" officially, but apparently people on HN don't know anyone in the field who is literally on the front lines researching this. The overwhelming opinion (articles aren't being written yet, expect some in a few weeks) is that the Pfizer vaccine does not actually prevent spread of the virus, only symptoms which decreases the probability of spread, but does not completely prevent spread.
