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...

Which is also one of the reasons that the vaccines against COVID were doomed to fail.
There are two coronaviruses that cause the common cold. Another one caused bronchitis and a fourth caused pneumonia.
So I was right - I saw the doctor that did the study on YouTube. The T cells attack the inner protein of the Corona Virus, not the Spike Protein. Spike proteins constantly mutate, but the inner protein stays constant. So it is possible to create a vaccine that will be sufficient against all varieties of the Corona virus, since the inner protein is nearly identical in all variants.
