Why are studies on how effective antibodies attained from having covid 19 are at future immunity so much more inconclusive than studies on effectiveness of the vaccine?

Posted: 24 May 2021 07:40 AM PDT

It seems that there is consensus that having Covid gives an individual some sort of immunity going forward, but when looking up how effective that immunity is, every resource tends to state that the level of immunity is unknown and everyone should just get vaccinated. How is it that we've had much more time to study the effectiveness of antibodies attained from having covid than the time we've had to study the vaccine, but the studies on the effectiveness of the vaccine are presented to be much more conclusive?

Punctured Lung in ancient times?

Posted: 23 May 2021 05:17 PM PDT

How likely was it to survive a punctured, and collapsed lung back in the stone age or antiquity?

If someone got an arrow into the chest, and the lung was pierced, would it be possible for that person to survive if no serious infection occured?
And if someone survived something like that, how likely was it that the lungs would be left with some sort of damage?

When we recover from a viral infection, does the infected cells actually recover or do they get removed and replaced by new healthy cells?

Why does administering a vaccine to a sick person not cure an existing infection?

Posted: 23 May 2021 06:41 PM PDT

If a vaccine trains your body to make antibodies for a pathogen, why is it ineffective when administering to an already sick person?

For example, administering a vaccine to someone already sick with COVID-19 or to someone with a chronic infection like HSV-1/2?

EDIT question extension:

If the harmless antigens look the same as the real infection but are easier to take down, despite fighting on two front, would the body be able to produce effective antibodies faster from the easy to target vaccine antigens - reducing the sickness duration?

Additionally, if the person is infected with a chronic illness such as HSV-1/2 where viral load spikes occasionally, would administering a vaccine during the down time train the body to destroy the virus?

Is there anything scientists can do or observe to infer how long the COVID vaccines will last?

Posted: 23 May 2021 07:27 PM PDT

At the moment, it seems to be that scientists just keep checking antibodies after x amount of time and then say "so far, it seems good for x amount of time." Is there anything they can do to determine the longevity of the vaccines?

What is the most recent R0 (R-naught) value of covid?

Posted: 23 May 2021 10:16 AM PDT

All things being equal, how contagious is this virus? I haven't heard an update I several months.

Furthermore.... if someone wears a mask, how much lower does the R0 factor drop? And how much does social distancing drop it? If this thing is going to get beaten, information like this will go a long way in convincing people to do these things.

Why are common allergens common?

Posted: 23 May 2021 04:16 AM PDT

I had to learn the common allergens as part of a food safety course, but it's only now that I wonder what makes these allergies more common than others?

What is the exact mechanism by which acidosis/alkalosis causes a decrease/increase in neuronal excitability respectivly?

Posted: 23 May 2021 05:15 AM PDT

My lecture mentioned that acidosis causes a decrease in neuronal excitibility while alkalosis causes an increase in neuronal excitibilty, however the mechanism of how this happens was not explained.

I tried googling and discovered this answer

However this "answer" raises more questions than it answers. For example, what is the mechanism by which alkalosis cause hypokalemia? and if there's hypokalemia this will cause hyperpolarization which actually should decrease not increase excitibilty so how is this explained?

And if so: are some of the symptoms similar to those of humans (avoiding eye contact, etc.)?
