Covid 19 Question
 

If someone has had Covid 19 and is now testing negative are the immune? Would they still need the vaccine?

Should I get vaccinated if I have already had COVID-19?

Getting COVID-19 might offer some natural protection or immunity from reinfection with the virus that causes COVID-19. But it's not clear how long this protection lasts. Because reinfection is possible and COVID-19 can cause severe medical complications, it's recommended that people who have already had COVID-19 get a COVID-19 vaccine. If you’ve had COVID-19, wait until 90 days after your diagnosis to get a COVID-19 vaccine.

So that's about 25 million people who should be toward the end fo the line.

No one knows with certainty. For starters, the tests for covid disease have both false negatives and false positives, thus having been diagnosed as having Covid is not 100% accurate. Some tests are better than others. There is likely, but not proven, differences in the immunity conferred by clinical illness. In many diseases the sicker you are, the more vigorous your immune response. So a mild or asymptomatic case of Covid may not give as good protection against further attack. Again however, this is NOT yet established. Covid has only been around for a year so nobody can tell you what happens 18 months after the disease much less 5 years.

In the absence of excellent data, the prudent and recommended approach, at this time, is that regardless of a person's history of Covid disease, they should still receive vaccination. It may be that at some time in the future that recommendation may change.

Can you get the flu again? Why not the COVID? IMO it will be just like flu with many strands which vac will have to altered to different strand?

Bet it’s been in the lab lot longer than year. IMO it just got released year or more go? Intentionally or in-intentionally?

I suspect that, in the near future, there will be some activities that will require you to have had a Covid-19 vaccination - flying, cruising, overseas travel? - so it would make sense to be vaccinated anyway if you intend to do any of those things.
