A new study of hundreds of residents of Kentucky reveals more realistic data showing that the COVID-19 vaccine provides better protection against reinfection than innate immunity.
Of the nearly 740 people who previously tested positive for coronavirus, those who remained unvaccinated were more than twice as likely to be re-infected with COVID-19 than those who were fully vaccinated. had.
NS Survey resultsThe US Centers for Disease Control and Prevention announced on Friday that even when infected with COVID-19, a particularly contagious variant of the coronavirus continues to hospitalize and kill hundreds of people each day. It has been suggested that vaccination acts as an additional layer of defense against reinfection.
“Even if you have been infected with COVID-19 before, get vaccinated,” said CDC Director Dr. Rochelle Walensky in a statement. “Vaccination is the best way to protect yourself and others around you, especially because more contagious delta variants are spreading throughout the country.”
The new study adds to existing evidence that infected and vaccinated people are more likely to suffer from milder and shorter illnesses than unvaccinated people. According to experts, this suggests that the virus is unlikely to spread to others. Less coughing and sneezing means less chance of the virus infecting others.
However, Delta Variant disagrees with this idea.
Delta loads more virus particles into people
The latest data is the delta variant More contagious According to the CDC, it is as contagious as chickenpox, than the common cold, smallpox, Ebola, flu, and the 1918 “Spanish flu.”
Part of the reason is that variants arm people with many viral particles in their nose and throat, causing more serious illnesses that increase the risk of hospitalization and death.
NS study According to a survey from China, the viral load of Delta-infected persons was about 1,000 times that of those infected with the original version of the coronavirus.
Despite vaccination status, age, or other health status, the delta variant remains at 120% higher risk of hospitalization, 287% higher risk of hospitalization in the intensive care unit, and 137% higher risk of death. That is. study From Canada.
Regardless of how immunity is acquired, it is unknown who the body produces effective antibodies against the virus and why they last longer than others. Doctors speculate that age and certain medical conditions may play a role.
“Vaccines save your life”
But so far, there is evidence that the vaccine “is doing exactly what it was supposed to do. It prevents serious illness, hospitalization, and death,” Warrensky said in COVID-19 at the White House. .. briefing on Monday.
As of August 2, when more than 164 million people were fully vaccinated in the United States, the CDC reported 7,525. Breakthrough infectious disease Among those who have been vaccinated with enough illness to be hospitalized or die. A total of 1,507 people have died. This is less than 0.001% of those who were fully vaccinated at the time.
“people You need to be relieved Vaccine expert Dr. Paul Offit is very likely to be protected from severe or serious illness, the illness that causes hospitalization or death from the virus, if fully vaccinated. I think. He told The Washington Post at the Philadelphia Children’s Hospital. “Vaccines save your life.”
As of August 5, more than 165.6 million Americans have been fully vaccinated with COVID-19, according to the CDC. That’s about 50% of the US population. Tracker..
