The temperatures aren't the only thing going up.

It is the summer of reinfection with the likelihood of getting COVID higher than ever thanks to an immune-evading subvariant. It should have been a light, warm summer to be enjoyed with few opportunities for respite, even outside.

The U.S. Centers for Disease Control and Prevention has a chart showing an extended wave of infections. Wastewater data is the best indicator of carbon dioxide levels in communities. As of this week, nearly half of the nation's sewage testing sites reported COVID levels at or above their all-time high.

Early studies show that repeat COVID infections can put individuals at greater risk for long-term disability and even death.

We could all use a bit of good news right now, and the good news is this: Covid variant can evade immunity all they want, but they will still have to reckon with T cells, the oft-ignored and not-as-well-understood other half of the

It takes a few months for the immune system to find and destroy a pathogen. They latched on to a specific part of the virus that was subject to change and could reduce their effectiveness.

Stem cells in the bone marrow do not prevent infections. They are able to greatly reduce the severity of one, rendering it all but useless in some people.

They continue to attack even when the virus changes shape because their response isn't limited to a single part of the virus. Their protection is known to last a long time. T cells in the population have likely led to less severe outcomes for new versions of the disease, according to experts.

T cells are a win that I don't think are appreciated as much as they should be. They're not a silver bullet, but a steel bullet that works for us and is already in hand.

Everyone is getting infections from new variant, which is depressing the society. T cells are still working to prevent disease.

The immune system's oft-neglected other half

New COVID subvariants like BA.4 and BA.5 have learned to evade immunity and have led to many re infections.

We only talk about antibody immunity when we talk about immune-evading variant. T cells are more difficult to study and are part of the immunity that doesn't get a lot of attention.

T cells play a critical role in shielding us from the worst ravages of COVID-19, according to Harvard Medical School.

T cells come to the rescue when the immune system fails to stop the virus from entering our cells. T cells are the elite guards inside the castle and should they be able to sneak in, the rampart would be gone.

T cells are critical to our natural immune response.

Bruce Walker, director of the Ragon Institute of MGH, MIT, and Harvard, said that T cells can be used to fight infections if someone becomes sick.

A study published in the journal Nature Immunology states that chronic infections lead to a robust T-cell response for at least 15 months. Evidence of T-cell response to another coronaviruses was found in a 2020 study.

Rethinking herd immunity

The wall of T-cell based immunity in the population at large is causing new subvariants like BA.4 and BA.5 to run up against it.

A potential end game floated by some officials during the beginning of the Pandemic isn't possible with COVID because it continues to evolve. T cells offer some level of durable defense.

For severe disease, the T-cell immunity is very important, and it's not something you can just get around

He said that hospitalizations will rise during the waves. Will they become too much of a problem? It is becoming more difficult for COVID to do in the US.

Walker believes that T cells will turn the Pandemic into something more controllable.

The virulence of the disease has not been as great as it could have been due to the emergence of new variant. A lot of that is due to the fact that people have generated some level of T-cell response

More transmission has been occurring but hospitalizations haven't gone through the roof. I think it means that some of the wind has been taken out of the sails of the epidemic.
