According to recent CDC data, Connecticut is the only state showing a COVID-19 vaccination rate above 90%. This success is an execption, if averaged with data from the rest of the nation. The United States is currently experiencing terrors with the Sars-Cov-2 Delta strain proliferation, a more infectious variant than its predecessors. Also because as the pandemic epicenter, the so-called Lambda strain will soon arrive.
Data from the Centers for Disease Control and Prevention website indicate that vaccination is winning the battle. Ten U.S. states report receiving immunization in the 80-89% range. Twenty federal entities are protected in the 70-79% range. Three states show vaccination rates of 60-69% and for 16 states there is no information at all.
If the Delta variant is placed at the center of the national discussion, vaccination efforts must be redoubled. In the first place, it is the only barrier that works against the new strains that have developed. However, there is something more important. Those with natural immunity are not safe from the fourth letter of the Greek alphabet. This involves COVID-19 infectees and survivors who have not been vaccinated.
Discussion on Sars-Cov-2 Delta
The Sars-Cov-2 Delta variant makes it even more urgent to get vaccinated. It is recommended even if you have already had the coronavirus. So says Jennifer T. Grier, assistant professor of immunology at the University of South Carolina. She has spent her entire professional life researching host factors that contribute to antiviral immunity. “For us, it is important to understand the innate response to infection and identifying protective pathways following viral infection.”
Americans should take notes to this presentation by Dr. Grier. “The difference in immune response between vaccination and infection seems to be even greater when dealing with new variants.”
“In early July, two new studies were published that show COVID-19 vaccines, though slightly less effective than they are against the older strains of the virus.”
“Researchers looked at how antibodies bind to new variants of the coronavirus and found that people who were previously infected with coronavirus might be susceptible to the new strains, while people who were vaccinated were more likely to be protected.”
It is not a shielded process
There is one thing that needs to be emphasized. COVID-19 vaccines offer a safe and reliable route to immunity. Both against older strains and against emerging strains. “Especially against the new Sars-Cov-2 Delta variant,” the immunologist said.
The observation is aimed to those who talk about immunity as if it were a magic act. Especially since they avoid getting vaccinated and the nation’s average immunization rate is low.
Americans must acknowledge that post-infection immunity is unpredictable. “Immunity comes from the immune system’s ability to remember an infection,” the scientist said.
“Using this immune memory, the body will know how to fight off an infection if it encounters the pathogen again. Antibodies are proteins that can bind to a virus and prevent infection. T cells direct the removal of infected cells and viruses already bound by antibodies. These two are some of the main players that contribute to immunity.”
Everyone in the nation should be on notice that the Sars-Cov-2 Delta variant is spreading rapidly. Citizens should be vigilant because the new strain may cause different symptoms. A study from the United Kingdom states that the symptoms are similar to a cold. They include headache, runny nose and sore throat. The traditional picture of loss of smell, shortness of breath, fever and persistent cough may not appear.
It is also reported that the variant could be responsible for severe illness in some communities. Rochelle Walensky, director of the CDC, suggested in a briefing that the variant may be responsible for the increase in hospitalizations. Especially in some communities with low COVID-19 vaccination rates.
Delta will not be the last Sars-Cov-2 variant. Lambda is already active. It seems that face masks are the best protection.
