The annoying common cold may yet turn out to be a blessing if researchers with the Imperial College London are correct. Since the pandemic started, researchers have speculated that coronaviruses could offer some cross-reactive immunity against the Wuhan coronavirus (COVID-19), and growing evidence points to that direction.
Recent studies show that recovery from the common flu can also prevent infection from the coronavirus because of higher levels of T cells, now recognized as a layer of protection against COVID-19, present in the body of the recovered person.
Scientists involved in a recent study assessed close contacts of those newly diagnosed with COVID-19 to pinpoint when they were first exposed. They found that those who tested negative for COVID-19 had higher cross-reactive T cell levels.
Dr. Rhia Kundu, the lead author of the study, said that being exposed to the virus does not always result in infection, and they want to understand why.
The team took blood samples from volunteers within days of being exposed to SARS-CoV-2 to allow researchers to determine their T cell levels. Household contacts who did not test positive showed that they had significantly higher levels of pre-existing coronavirus-fighting T cells.
Further, the team found out that the high levels of pre-existing T cells created by the body when infected with other human coronaviruses like the common cold can protect people against the COVID-19 infection. (Related: The common cold can protect people against coronavirus, study finds.)
T cells induced by common cold can protect against infections
Another author, Ajir Lalvani, said that the study provides the clearest evidence that T cells induced by the common cold can play a protective role against infections, adding that the T cells provide protection by attacking proteins within the virus instead of the spike protein on its surface.
Lalvani said that the spike protein is under intense immune pressure from vaccine-induced antibodies, which could drive the evolution of vaccine mutants. In contrast, by targeting proteins internally with the protective T cells, the virus mutates less. Lalvani, however, added that “they are highly less conserved between the various SARS-CoV-2 variants, including omicron.”
Further, Lalvani noted that new vaccines that include conserved, internal proteins would induce broadly protective T cell responses that should protect against current and future variants. (Related: Professor says covid is becoming “just another cause of the common cold.”)
The available vaccines have proven to be less effective against the omicron strain, including against severe diseases. While booster shots restore some of the lost protection, early data shows that the boost drops its effectiveness against infection after it is administered into the body, and it is not yet clear whether or not the booster shots could maintain its protection longer.
Academics not fully sold on colds against COVID
Some academics not involved in the study warn that it could be a mistake to think that anyone who has had a cold caused by a coronavirus is protected against COVID.
An associate professor in cellular microbiology at the University of Reading, Dr. Simone Clarke, noted that while the study adds to findings on how the immune system can help fight the virus, it should not be “overinterpreted.”
He noted that it is “unlikely” that the 150,000 people who have died within a month of testing positive for COVID never had a cold caused by a coronavirus. He said that coronaviruses only account for 10 to 15 percent of colds, and it is a grave mistake for anyone to think that they are protected once they develop a cold.
“There is no measurement of how much protection the reported effect gives people,” he said. “A link is only hinted at, it has not been proven conclusively.”

ABC’s Hostin: Republicans Are Treating Biden Like a Black President
ABC legal analyst Sunny Hostin said Thursday on ABC’s “The View” that Republicans treated President Joe Biden like a black president.
Hostin said, “There are things that he has not gotten credit for, like he’s inherited this pandemic from the Trump administration. It was badly handled. He was able to pass a 1.9 trillion dollar relief package which a majority of Republicans voted against. That’s something that he gets credit for. I think he also gets credit for his incredibly diverse judicial nominations. I think there has been about 41 federal judges. Those are lifetime appointments.”
She continued, “I think where he hasn’t done well is basically delivering federal policy in favor of the people who put him in the White House, and that is communities of color. We didn’t see any movement on voting rights. We didn’t see any movement in police reform.”
Hostin added, “The infrastructure was a leaning-into white independence, and I think it was a leaning into white moderates, but the bottom line is, those aren’t the folks who really took him over the finish line. That is not the Democratic base. No Democratic president has made it into the White House without the support of the black community. The black community now, voters 50 and over that are registered, there’s been a 36-point drop in the net approval. What I took away was he said something like I had no idea that my Republican friends would do this. Well, he’s governing like it’s the 1990s. It’s 2022. He sat for eight years next to a black president yet didn’t think he would be treated like one, and that is what he is being treated like.”

Behar: ‘Dense’ Biden Thought Other White Privileged Senators Would Work with Him
Joy Behar told her co-hosts Thursday on ABC’s “The View” that President Joe Biden was “dense” for thinking his fellow “white privileged” senators would work with him.
Whoopi Goldberg said, “Part of the problem for Joe is none of us, none of us ever anticipated we would be sitting in front of senators and congresspeople who are denying the fact that someone won an election. I never saw that before. I don’t think it occurred to him that would ever be Republicans who would go that far to say this was a lie. I think a lot of this, he thought, you know, we’ll beat each other up as we have in the past. This is a whole new group.”
Behar said, “But, Whoopi n the ’90s Newt Gingrich, had a contract on America.”
Ana Navarro said, “With America.”
Behar shot back, “I like to say it was on America. Then you have Mitch McConnell say that his whole idea going forward with Obama was to make sure he was a one-term president. Then he said about Biden, we’re going to obstruct, and we’re not going to let him do anything he wants to do. So I mean, how dense was Biden really in these instances? You’re a white privilege senator in the United States Congress, so you believe other white privilege guys will work with you, but they won’t, and they don’t.”
