How Delta is changing advice for the vaccinated Vaccines are very safe against Covid-1, especially serious illnesses, but many have found breakthrough infections and new recommendations that vaccinated people should wear masks from time to time. I was confused and worried.
How Delta is changing advice for the vaccinated New studies show that vaccinated people can become infected and carry high levels of coronavirus, but this is rare and is predominant for those who become infected and spread the virus. It is important to remember that it is rare.
“Once vaccinated, we did the most important thing to keep you and your family and friends safe,” said Greg Gonzalves, an assistant professor of epidemiology at the Yale School of Public Health. “The idea is that vaccinated people have more freedom, but not all are the same as in the summer of 2019.”
Why should I worry about Delta when I am vaccinated?
No vaccine provides 100% protection. Erin Bromez, a comparative immunology scholar and professor of biology at Dartmouth College, Massachusetts University, said she considers vaccine antibodies to be breakwaters designed to protect cities from storm surges. In most cases, the walls will withstand shock waves, but hurricanes can be strong enough for water to enter. Compared to previous forms of virus, Delta resembles a virus hurricane. It is much more contagious and presents a major challenge for the vaccinated immune system.
“Vaccines provide additional protection that is not normally available,” says Bromez. “But when faced with major challenges, such as approaching an unhappy person with a high viral load, that barrier cannot always be maintained.”
The good news is that the current crops of vaccines available in the United States do the amazing job of protecting people from serious illness, hospitalization, and death. Over 97% of people were hospitalized with Covid-1 without vaccination. Also, new data from Singapore show that vaccinated patients who are hospitalized for a delta breakthrough infection require less oxygenation and are less likely to clear the virus faster than vaccinated patients. increase.
What is the real risk of a breakthrough infection after vaccination?
The breakthrough transition is a headline, but it remains unusual. The Centers for Disease Control and Prevention stopped tracking all breakthrough cases in May, but at least half of all states reported at least some breakthrough cases. The Kaiser Family Foundation recently analyzed a number of state-reported data and found that land mines, hospitalizations, and deaths were extremely rare among people who were fully vaccinated with Covid-1. According to Kaiser’s analysis, the breakthrough case rate reported among fully vaccinated individuals was “from 0.01% in Connecticut to 0.29% in Alaska, less than 1% in all reporting states.” ..
However, many breakthrough infections have probably not been reported. This is because the infected person has no symptoms or has mild symptoms that disappear before the person considers the test.
“Breakthrough infections are extremely rare, but without a population-based sample, the degree of rarity is unknown,” said Dr. Asf Beaton, executive director of Harvard TH’s Ariadne Brigam and Women’s Hospital and Lab. I am. .. The Chan School of Public Health in Boston. “There may be a lot of people with minor sores in their throats for a few days, but I don’t know. It’s not the vaccine failure that’s causing our breakthrough. Since the launch of the vaccine campaign, It is estimated to have saved 100,000 to 200,000 deaths.
What is clear is that giving Delta the opportunity to challenge the barriers provided by the vaccine increases the risk of breakthrough infections. The risk of a vaccinated person crossing the road with a high-load infected person when a large number of people gather, such as the July celebration in Statetown, Massachusetts, or the packed Lallapaluja concert in Chicago. Will be much higher.
“The more people we come in contact with, the higher the risk, but it also depends on the weather in the area at risk,” said Gonzalves. “Soon we will see an outbreak of Lallapaluja. Crushing all these people together is an ideal situation for the expansion of the Delta.
When should I wear a mask?
The CDC has a color-coded map of the outbreak of Covid-1 in the United States. The blue and yellow areas show relatively low levels of infection, and the orange and red areas show areas where there were more than 50 cases per 100,000 people last week. The agency recommends wearing a mask when living in an orange or red area. This is currently about 100 percent of US counties.
Infections are relatively low in most parts of the northeastern and central northeastern regions, with a significant increase in cases in Missouri, Arkansas, Louisiana, and Florida in the Delta.
