Very small study, but seems like common cold caused by other corona virus,

can create T- cells that protect against SARS-COV-2

 

Not bad if we can get some ekstra protection caused by a common cold.

 

 

Seasonal flu shot, as well as all vaxes related to lungs will protect from coinfection. 

Its not flu or covid viruses which kill directly, but complications after them. Some bacterial or fungal infection of breathing system. 

Viruses stay in body short time, around a week (like a flu), but patients experience serious problems later on, for weeks and months

Likely, yes.

 

A significant proportion of people don't even get covid or are asymptomatic.  Luck of the draw really.  I think I've had 150 or more significant colds in my life- can't believe that wouldn't add up to some form of durable t cell protection against the worst.

 

But the state of your immune system now is important.

There is some reason why so many people are asymptomatic, whereas others die. Same for some people who never get infected. 

 

No one seems to understand this.

Some of it is due to luck.  The first line of defense is the innate immune system -- we are born with that and it is on guard for any foreign pathogen 24/7.  I suspect a fair number of people have been lucky enough to have an immune system that clears it out without ever getting us sick.  A part of this probably has to do with how big a dose of virus we get and how viable it is.  

 

If the innate system doesn't get it, it calls up the adaptive immune system and that's the point where we start getting sick.  It takes anywhere from a matter of days to a week for the immune system to kick in and produce antibodies.   The adaptive immune system has to identify the exact protein to target and that is done by trial and error.  For some, this happens quickly, for others a little less quickly.  

 

The adaptive immune system sends out cytokines and starts an inflammatory response.  Inflammation is caused by blood and fluid leaking around the area of infection.  Inflammation helps to secure the 'battlefield' and provides fluids for the immune cells to move around in. 

The immune cells start killing the virus and also signal the infected cells to die -- our immune cells can't actually enter an infected cell, so when a cell is infected it has to be killed. 

 

A lot of inflammation becomes dangerous and the larger the area of infection, the more inflammation and the more cells that have to be killed. 

 

If the immune system over reacts, it goes nuclear and we end up with all kinds of problems.  

 

If all goes well and our adaptive immune system captures it early and while the virus is limited, we get a little inflammation, a little fever from a specific cytokine cell, pyrogens.  Heat can interfere with reproduction, and we lose our appetite and feel tired.  Our body does not want to waste energy while fighting the virus and digestion takes a lot of energy, so it slows down and tiredness sort of forces us to rest.  

 

That's a lot of stuff that has to work and everything has to work when and how it is supposed to.

The key part is "common cold caused by other corona virus".  There are many, many virus types that cause the common cold.  Only about 20% of colds are caused by coronaviruses.  

To my knowledge there are no or few vaccinations for common colds....but we do have some very effective vaccinations that can greatly minimize serious illness, hospitalizations and deaths from covid....if only everyone would get the shots we would have had significantly fewer disruptions to lives, economies, healthcare systems. travel. etc....but sadly many prefer to argue ad nauseum against getting the covid vax rather than take 20 mins to get the shots.

The common cold is caused by a number of different viruses, most commonly by a Rhinoviruses.  Coronaviruses cause about 20% of colds.  Perhaps you happen to be lucky enough to have had a recent cold and it was caused by a coronavirus, you will have some immunity to other coronaviruses including Covid.

or just get the covid shots?

It's not about getting a cold and then you're protected.

It's about that a common cold from a Corona virus, could give you some extra protection.

 

So if you had 2 or 3 shots, and then a few months later get a common cold from a Corona virus, then your anti bodies will rise again, which can't be a bad thing, when we're talking about protection against covid.

 

Of course the people who do not get the vaccines, can get some protection too from a cold, but that's not the most viable solution.
