The common cold can provide some protection from COVID-19, according to new research led by Imperial College London, which says the findings provide a blueprint for future vaccines that could offer immunity to all variants of the coronavirus.
Since the start of the pandemic, scientists have questioned why some people are able to resist coronavirus infection despite prolonged exposure, while others are easily infected. The researchers set out to test a theory that a type of white blood cells called T cells, produced by the human body to fight the cold, could offer some protection.
"Previous infection with common cold coronaviruses — these are distantly related cousins of SARS-CoV-2 which causes COVID-19 — infection with those might induce T cells that would be able to cross-recognize and then attack the SARS-CoV-2 virus. That was the theory that we set about to test," report co-author Ajit Lalvani, chair in infectious diseases at Imperial College London, said in an interview with VOA.
The study began in September 2020 before any mass vaccination programs and before most people had been infected with COVID-19.
Scientists sampled the blood of 52 people who lived in the same household as someone infected with the SARS-CoV-2 virus. The sampling took place immediately after the COVID-19 diagnosis was confirmed.
Exactly half of those sampled contracted COVID-19, while the others did not.
"Those contacts who had preexisting T cells that were induced by common cold coronavirus (and which could) cross-recognize and attack SARS-CoV-2 people with such T cells didn't get infected," Lalvani said...

Not really, they haven’t been able to make a vaccine for the common cold for decades.
My T-cells are tired.
They can’t make a SINGLE common cold vaccine - but they could make one for the Corona Virus I believe … based on my high school education - someone correct if I’m wrong
There are apparently hundreds of types of “common cold virus,” some rhino- and some corona-virus.
... and also adeno- and entero-viruses.
Thanks, although this is not new news but confirmatory of past reports:
[November 23, 2021] Exposure to Harmless Coronaviruses Boosts COVID-19 Immunity
No kidding…..
And they went to medical school to figure this out?
So, the lockdowns were to keep people from getting colds?
A cold is in the family of coronavirus.
Not in the sense of a vaccine.
They should have just let things run their course. The hyper-cleaning everything wiped out others, that could have been beneficial.
something is missing here. Who hasn’t had a cold? Do they mean someone who recently had a cold? I usually have 1 or 2 colds a year, and with me they are rough. Since wearing a mask and sanitizers .. zero colds
“We could just made a vaccine from the cold virus ?”
No, we have never made a successful vaccine using/against the cold virus (really the coronavirus strains of “common cold” type), because we just can’t do it. By the time you could manufacture a potential vaccine, the coronavirus would have already mutated into a different form and your vaccine would be ineffective.
Which is also one of the reasons that the vaccines against COVID were doomed to fail.
Not all cold viruses are coronaviruses. So you could have gotten 2 or 3 colds in 2019, and it could be that none of them were the “right kind” of cold to give you this protection.
so I might have had "it" but otherwise, I worked on a hospital floor with covid patients, even though I didn't take direct care of them, I'm overweight, diabetic, and have high blood pressure supposedly....
except for that 2019 illness, I've been well...so has this household...no vaxx...no covid.
I’m reading that folks are hoarding all the cold medicines now because they can help ward off Covid.
An occasional beer has worked for me for the last 2+ years.
I credit my immunity to my Celtic and West Germanic Neanderthal haplotype. And that really bad flu I had in 1967. I have been in multiple COVID spreader events, air travel a lot, in households with people with COVID, and if I had it, it was so mild I didn’t notice.
Guess it didn’t work for me.
I’ve had many colds over my life. Surely one of them was a coronavirus.
Got COVID-19 last year.
