NEW YORK (CBSNewYork) — As you’ve heard, members of the New York Yankees organization, including infielder Gleyber Torres, have tested positive for COVID-19 even though they were reportedly vaccinated.
How, why, and to whom does this so-called “breakthrough” COVID happen?READ MORE: CDC Announces New Mask Guidance For People Fully Vaccinated Against COVID-19

As CBS2’s Dr. Max Gomez reported Thursday, the first thing to know is that no vaccine is 100% effective and while all three COVID vaccines have proven to be extremely effective at preventing serious disease, hospitalization and especially death from the coronavirus, some breakthroughs can and have happened.

There are so many possible variables that can contribute to a vaccine breakthrough. The individual’s own immune system may not respond well enough. He or she may have been exposed to a COVID variant that wasn’t fully prevented by the vaccine, or they may have tested positive before the vaccine had a chance to fully rev up immunity.
That said, Dr. Thomas Balcezak, the chief clinical officer for the Yale New Haven Health System, says you also have to understand how vaccines work.
“They either prevent the virus from entering the body or put a stop to it once it begins replicating. So with all vaccines for COVID-19, it’s possible that the virus can enter your cells, begin replicating and then be stopped after they begin replicating, therefore presenting a period of time when you may test positive and may be asymptomatic,” Balcezak said.

In other words, test three times a day as the Yankees do, and you’re likely to find a positive test in someone who isn’t sick. That’s all but one of the positive Yankees coaches, and who may never get sick thanks to the vaccine. Not to mention that the shots dramatically reduce an infected person’s ability to spread the virus to others.MORE NEWS: Long Island Resident Zachary Honig Accused Of Stealing And Forging COVID-19 Vaccination Cards
There have been a few thousand so-called breakthrough cases, but it’s hard to tell how many of those got truly sick and that’s compared to nearly 120 million Americans fully vaccinated. That works out to less than a thousandth of 1%.

COVID-19: There Could Be Some Long-Term Loss Of Brain Tissue From Virus, New Study Says
There could be some long-term loss of brain tissue from COVID-19 that would have some lingering consequences, according to a brand-new study.
That loss of brain tissue may explain why COVID patients lost their sense of smell, according to the study, which was conducted in the United Kingdom.
"They looked at people who had had MRI scans of their brains in the past three years and they looked at how many developed COVID and about 300 people, a little over 300 people developed COVID," said former Food and Drug Administration Director Dr. Scott Gottlieb on CBS-TV's "Face the Nation" on Sunday, June 20. "And when they compared those individuals who developed COVID against matched controls, people who were similar, who didn't develop COVID, they saw a pretty persistent decline in certain brain tissue matter."
That decline in brain tissue could explain why some COVID patients lost their sense of smell.
"It's very concerning because it does suggest that the virus could be having a direct effect on certain portions of the brain," Gottlieb said. "And if parts of the brain that showed the shrinkage actually are responsible for things like taste and smell and memory, the kinds of conditions, the kinds of complaints that we see COVID patients having after their recovery.
"They're still complaining about difficulty with smell or taste or problems with memory. So this is concerning."
The study also indicates COVID is a disease that could create persistent symptoms, Gottlieb noted.
"There's this 'Long COVID' some people clearly have persistent symptoms after recovery and it does appear to affect the neurological symptom system, both the brain and perhaps the autonomic nervous system," said Gottlieb, author of "Uncontrolled Spread: Why COVID-19 Crushed Us and How We Can Defeat the Next Pandemic," a soon-to-be-released book. "You see people with persistent tachycardias, persistent fast heart rates, for example.
"That could be explained by some damage to the nervous system. So this isn't a benign disease. This is something you want to avoid. And the bottom line is we have the tools to avoid it through vaccination."
