British scientists are experimenting with a new antibody therapy that has the potential to immediately immunize people and prevent disease after exposure to Covid-19.
If it is too late to provide a vaccine, the drug will provide immediate and long-term protection to patients, which may save thousands of lives.
It can be used as an emergency treatment measure for hospitalized patients, nursing home residents and college students to help reduce the spread of the virus.
People who live with someone who are infected or exposed to COVID can inject drugs to stop their infection, even if they do not have a coronavirus vaccine.
British scientists at the University College Hospital NHS (UCLH) in London have injected the drug into ten people as part of a new trial called “Storm Chaser”
They hope this treatment will provide protection for Covid-19 between six months and one year.

UCLH scientists also started a second clinical trial called Provent to examine the use of the antibody in people who may not benefit from the vaccine, such as patients with compromised immune systems or patients at increased risk due to Covid-19 infection Affected by factors such as age and existing conditions.
After the study entered the third phase of the trial on December 2, UCLH injected ten people, including medical staff and college students, into the Storm Chaser trial at its new vaccine research center.
The main population of the trial includes medical staff, students who live with it, and patients who have recently been in contact with Covid-19, as well as long-term caregivers, military and industrial personnel, such as factory workers.
In the first trial, the antibody developed by the pharmaceutical company AstraZeneca was called AZD7442. The company also developed a vaccine in collaboration with Oxford University, which is awaiting approval from the Medicines and Medical Products Regulatory Agency (MHRA).
At the same time, the elderly and long-term caregivers, as well as people suffering from diseases such as cancer and HIV, will be recruited to participate in the Provent trial.
Dr. Catherine Houlihan, a UCLH virologist who led the Storm Chaser trial, said: “We know this combination of antibodies can neutralize the virus, so we hope to find that this treatment given by injection can immediately prevent Covid-19 of the people who have been exposed -It is too late to provide vaccines.
The Guardian reported that Dr. Hu Lihan said that this therapy would be an “exciting complement” to the efforts being tested and developed to fight the coronavirus.
She said: “If we can prove that this treatment is effective and prevent people exposed to this virus from continuing to develop Covid-19, it will be an exciting addition to the arsenal developed to combat this terrible virus.”
Dr. Nicky Longley, a UCLH infectious disease consultant who leads the university’s Provent department, said: “We want to assure anyone who may not be able to use the vaccine that we can provide equally protective alternatives.”
Paul Hunter, a professor of medicine at the University of East Anglia and an infectious disease expert, said the new treatment in the Storm Chaser trial could save thousands of lives.
“If you are dealing with an outbreak such as a nursing home, or if the patients you encounter are particularly at risk of developing Covid, such as the elderly, then this is likely to save a lot of lives. If this is proven in the third phase of the experiment, it can play an important role in maintaining people who are alive or would die. So this should be a big deal,” he said.
“If you have an outbreak in a nursing home, you may want to use this type of antibody mixture to control the epidemic as quickly as possible by distributing the drug to everyone in the nursing home (residents and staff).”
“Similarly, if you live with your elderly grandmother and you or other people in the house are infected, then you can give her this to protect her.”
The potential breakthrough of instant immunotherapy is gratifying news in the United States and the world. Nearly 119,000 Americans spent COVID-19 in the hospital on Christmas Day, and 1,541 deaths were recorded.
However, according to the COVID Tracking Project, on Friday, 20 states did not provide the latest information on their numbers, which means that the true number of deaths across the country may be higher.
After setting a new record of 120,151 last Friday, the overall number of hospitalizations on Friday fell to 118,948, and the 7-day average for Christmas climbed to a new high, reaching 117,029.
Last Friday, there were 124,498 new cases reported, but the COVID tracking project warned that the data has been affected by the holiday.
The average number of seven-day hospitalizations on Christmas Day hit a record high of 117,029, as nearly 1119,000 COVID-19 patients spent their holidays in hospitals
Across the country, more than 18.7 million Americans have been infected with the coronavirus and 330,246 people have died.
The state that did not provide any updates on new cases and deaths last Friday is California. After 300,000 new cases were reported last week, the epidemic has brought the medical system to a critical point.
Earlier this week, it became the first state to exceed 2 million cases, as experts still worry about a further surge that Christmas and New Year travelers may cause.
