The United States is now dealing with a delta variant of the corona virus, a highly contagious variant that was first identified in India in December.
As with previous variations, the delta’s shape has spread to many countries around the world, including the United Kingdom, where it is now responsible for about 99% of new cases.
The United States first announced that there was a confirmed COVID-19 case with a Delta variant in March this year. It is now the dominant type in the country, accounting for 82% of all new infections in the country.
In the United States, the number of cases of Covid 19 is increasing rapidly. The average number of daily COVID-19 cases is over 67,000, according to the Centers for Disease Control and Prevention (CDC).
According to research, this increase is partly attributed to the delta variation, which is estimated at 60%.
A recent study by the Chinese Academy of Medical Sciences also found that “the viral load in delta infections is [approximately] 1000 times higher” due to previous SARS-CoV-2 variants.
In addition, areas where vaccination rates are low are more likely to increase the risk of infection.
Low vaccine uptake driving up infections
Less vaccines increase the risk of optic infections.
“Immunized people are at higher risk of infection,” he said. Dr. Mary Smith, head of infectious disease at Long Island Jewish Forest Hills Teaching Hospital, said that if the strain continued to grow rapidly, especially in areas with low vaccination rates, the United States could see an increase in SARS-CoV-2 infection. ۔ Queens, New York City.
CDC Director Dr. Rochelle Valensky Trusted Sources issued a warning earlier this month about the possible increase.
In a press briefing, he said that preliminary figures show that 99.5% of people who have died from covid 19 since January have been vaccinated.
“We know that Delta varieties are currently growing in the country’s pockets with low vaccination rates,” he said.
In Missouri, where the vaccination rate is 40 percent, there has been an increase in confirmed coronavirus infections in recent weeks.
In contrast, Vermont reported only 213 cases last week and currently has the highest vaccination rate in the country at 68 percent.
This echoes the findings of a UK study that found that Delta variants were twice as likely to be hospitalized, and that the AstraZeneca-Oxford and Pfizer-Biotech Covid 19 vaccines were effective in reducing this risk.
“We also know that our authorized vaccine prevents delta variants from severe illness, hospitalization and death,” Valensky said.
Dr. Theodore Strange, interim chair of medicine at Staten Island University Hospital in New York, said the data support that.
“The safety and efficacy of the current vaccine is very clear. All three vaccines work to prevent disease and the spread of the disease, and they are as safe as any other vaccine that is being used. Although some side effects have been reported. Granted, these problems are rare and treatable, “he told HealthLine.
Vaccine development in the United States
The United States has so far delivered more than 346 million doses of the Covid 19 vaccine.
More than 164.9 million people have received two doses. This means that more than two-thirds of the US population over the age of 12 – or 67.6%, is accurately – fully vaccinated.
There are currently three Covid 19 vaccines adopted by the Food and Drug Administration (FDA) and currently in use throughout the United States.
The Pfizer-BioNTech vaccine was the first to receive a Trusted Source Emergency Standards Authority (EUA) from the FDA. It is sold under the brand name Comirnaty and is also called BNT162b2. Currently, more than 193 million doses of the vaccine are being given in the United States.
A week after the Pfizer-BioNTech vaccine EUA, the Moderna vaccine also received the green light from an FDATrusted source. Sold under the brand name of Speck Wax and also known as mRNA-1273, more than 139 million doses of the modern vaccine have been given in the United States so far.
The third vaccine approved by the FDA was the Johnson & Johnson Covid 19 vaccine, or Johnson Covid 19 vaccine. The EUA was issued in February 2021. So far, more than 13.4 million doses have been given.
Vaccines vs. Deltas
All three vaccines have been shown to be effective against varying degrees of SARS-CoV-2, the original form of corona virus, which causes COVID-19.
However, since Delta’s appearance, scientists have been trying to determine whether the vaccine is effective against it.
We broke the current data. But new research could mean that this data will change over time.
Time for a Covid-19 Booster
COVID-19 Vaccine Booster Time?
In data released July 28, Pfizer said a third dose of its COVID-19 vaccine had “strongly” increased protection against the Delta variety compared to its standard two doses.
According to the trial results, the third dose produces five times more antibodies against the Delta variant in people aged 18 to 55 and 11 times more antibodies in people aged 65 to 85. The study is awaiting peer review.
Statistics indicate that Israel is the first country to launch a third shot on a large scale. Currently, people over the age of 60 are being invited to the meeting.
The Israeli Ministry of Health said the decision also took into account its own national health statistics, which show that people vaccinated in April are 75 percent protected from infection, according to reports. Immunization coverage in January was less than 16%
However, Smith told HealthLine that currently available vaccines have been widely effective in preventing severe disease, including those identified by various types of current concerns, so far without a booster.
Furthermore, the CDC has not recommended any post-vaccine booster against SARS-CoV-2, as current data is limited.
The performance of various Covid-19 vaccines is different among people. The Delta Variant is the latest version of Covid-19 which is considered as the most lethal type of Covid-19.
