When considering COVID-19 as a threat, masks and vaccines should be the first line. If you have COVID-19 and are at risk for severe illness, monoclonal antibody may be a good option.
For people who are in a high-risk group of getting severe COVID, “the game isn’t over. There is still this back-up plan available that can help them to better protect themselves from the virus,” said Deborah Fuller, a microbiologist at the University of Washington School of Medicine who is working on coronavirus vaccines.
Monoclonal antibody treatments are infusions of lab-made proteins that mimic the immune system’s ability to fight off COVID. Although the Food and Drug Administration gave these treatments — like Regeneron — emergency use authorization in 2020These criteria have been expanded to make it easier for people to apply.
MayFDA removed age limits and introduced new eligibility criteria like pregnancy. In August, people who have “post-exposure prophylaxis” ― meaning they were exposed to COVID and are at high risk of getting severe COVID ― became eligible to receive Regeneron. In September, pharmaceutical company Eli Lilly’s monoclonal antibody cocktail also got approvedFDA approved the use of this medication as preventative treatment in cases where people have been affected by COVID.
This COVID therapy can be used to make dramatic improvements in patients’ lives. However, millions of Americans have not yet been informed. According to the U.S. Department of Health and Human Services, 3.2 Million doses had been distributed in America as of Thursday. However, 52% of those doses were used.
“Most people that test positive for symptomatic COVID-19 are actually eligible for this treatment because they have one or more risk factors for severe disease, but the vast majority of them do not even know about this treatment,” said Adit Ginde, an epidemiologist at the University of Colorado School of Medicine and an emergency department physician at UCHealth, a Colorado-based health system.
Here’s everything you need to know about what the treatment can and cannot do, and the critical difference between getting a treatment and getting a vaccine.
How do monoclonal antibodies work and what is it?
There are three monoclonal anti-covid-19 treatments that have FDA authorization. sotrovimabGlaxoSmithKline manufactures.
The main drug in use in America is Regeneron’s antibody cocktail, which is what former President Donald Trumphad when he was in hospital with COVID October 2020. Federal government paused distribution of Eli Lilly’s antibody cocktail in June over concerns about ineffectiveness against the gamma and beta coronavirus variants, but resumed distribution in AugustCertain states may allow this. citingThe prevalence of the Delta variant is what makes the drug effective.
Once they have entered your body, monoclonal antibody find and bind the spike protein from the SARS/CoV-2 virus. This causes COVID-19. Once attached, these artificial antibodies can interfere with the virus’s ability to enter your cellsIt is possible to.
To get the treatment administered, you’ll get antibodies either by four subcutaneous injections in areas like your arms and belly in quick succession, or the treatment will be given to you through a vein intravenously that can take between 20 minutes to an hour or longer. For any side effects, you will be monitored by a healthcare provider for at most an hour.
While subcutaneous injections can feel less invasive, “intravenous delivery of monoclonal antibodies [is] by far the most efficient way to get monoclonal antibodies in your body very quickly,” Fuller said.
That’s why in severe situations, providers are more likely to go the IV route because “they are going to want to pump that directly into your veins to get it distributed through your body much more quickly,” she said.
Monoclonal anti-body treatment is available to all eligible individuals
The COVID-19 antibody cocktail cocktails may be available to you if you feel you’re at risk of serious COVID-19 progression, which could lead to death or hospitalization.
Under the FDA’s emergency use authorizationThese conditions can be:
- Being over 65 years old
- Obesity and being overweight
- Chronic kidney disease
- Immunosuppressive disease or immunosuppressive treatment
- Cardiovascular disease
- Chronic lung diseases
- Sickle cell disease
- Brain disorders, such as cerebral palsy or neurodevelopmental disorder like cerebral palsy.
- A medical-related technical dependence, such as gastrostomy or tracheostomy
- Considerations like race, ethnicity and gender could put people at risk of developing severe COVID-19.
If you are in one of these high-risk categories, you can get monoclonal antibody treatment even if you’re fully vaccinated.
It could also be possible to qualify for the grant as a stipend. preventative treatmentIf you’re at risk for severe COVID or have had COVID exposure.
Is it really that effective?
Ginde stated that it is a lifesaving treatment if administered promptly. NumerousClinical trials show that treatment for severe COVID patients can reduce the likelihood of death and hospitalization.
“Patients feel very sick, they feel like they are really struggling to breathe … [Then] they get this treatment,” He stated. “You’ll hear not infrequently reports of people that are that sick ― that within even six to 12 hours ― feeling like they’ve taken a dramatic turn to the better.”
One study on Regeneron’s antibody cocktail (that has not been peer-reviewed) found that it shortened COVID symptoms by four days and more rapidly reduced viral load compared to people who got a placebo.
The monoclonal antibodies may also help to reduce the risk of COVID spreading to others who are in close proximity. It was found in one study that this is a good idea. reduced the riskYou could contract a symptomatic illness from someone living in your home who is suffering from COVID at 81%
What time do I have to receive the treatment?
Monoclonal antibodies are used to treat mild-moderate COVID in children aged 12 and older, as well as to stop the development of severe COVID.
“The earlier, the better,” Ginde said. “Once you are hospitalized, it’s too late.”
It is possible to have a 10-day windowThe Centers for Disease Control and Prevention recommends that you seek medical treatment as soon as symptoms begin. If you wait longer, “by then the virus has ravaged the body. And there’s not a whole lot the infusion of monoclonal antibodies is going to do to be able to reverse the course of the disease,” Fuller said. You should seek treatment as soon as possible if you suspect you may have been exposed.
What monoclonal antibodies can be used to treat COVID-19
As the Department of Health and Human Services explains, accessibility varies by state. determinesOn a weekly basis, how much of the nation’s supply is distributed. The distribution of the national supply is then decided by different health departments in each state or territory.
Florida and Texas are two examples. People can determine their eligibility by themselves and then there is a regional walk in center that allows them to receive treatment. In Colorado, Ginde said, There is an online referral system that allows providers to send eligible patients.
The Department of Health and Human Services keeps a list of. national databaseYou can find out more information about where the treatment is available.
“Part of it is demonstrating demand as well, the more people ― the community, the public, the providers that really want this treatment ― the more that will help move the needle on expanding access,” Ginde said.
Do side effects exist?
It’s rare but possible to have side effects. It is possible to have side effects. 1% of subjects receiving Regeneron’s antibody cocktail in a Phase 3 trial got skin redness and itchiness at the injection site, according to the FDA.
There have also been monoclonal anti-infusion reactions. includedThe following symptoms may occur: headaches, fever, nausea, vomiting, stomach pain, neck irritation, throat irritation, skin rashes, and dizziness.
It costs how much?
Federal government covers the costs of monoclonal antibodies therapies. It is therefore free. However, if your insurance has one, you might have to pay an administration fee.
Is the COVID-19 vaccine required?
Monoclonal antibodies therapy cannot be used in place of vaccination. VFuller stated that the accination of COVID-19 will create a memory reaction in your immune system, which protects you from being exposed to COVID. Meanwhile, the monoclonal antibody therapy builds no memory and “protects you for that moment but then it goes away,” she said.
The big difference between COVID and other COVID treatments is the fact that although there may be a short window for treatment, COVID vaccines have permanent memory cells which can immediately produce antibodies.
“Vaccines are so much better because they are there waiting and ready to shut down the virus before it can even get going, whereas with monoclonal antibodies, you don’t take those until the virus has a head start and you are going to have to chase it,” Fuller said.
Can you receive the same antibody treatment twice?
While COVID-19 vaccines give you lasting protection, a monoclonal antibody infusion “is really maybe good only once or twice,” Fuller said. “You cannot rely on it repeatedly to protect you from COVID.”
If you get it more than once, “your body is going to respond to that therapy differently than it did the first time because it has seen it before,” Fuller said. “It’s going to potentially dampen its potency, you may potentially develop an immune response against that first infusion.”
To receive a COVID-19-vaccination, you must wait at least 90 days following the receipt of monoclonal antibody vaccines.
The CDC has warned that monoclonal anti-body treatment could interfere with a vaccine induced immune response. recommendsWait at least ninety days after treatment to receive a COVID shot.
But don’t expect to have the protection of monoclonal antibodies for those full 90 days in your body.
“At some point, it does hit a threshold where you would not be protected, and it’s a very short window of time ― weeks,” Fuller said, noting that every body is different but in about two to three weeks, the amount of monoclonal antibodies circulating in you can dip down to a level that would allow a COVID-19 infection.
“That’s in contrast of course with vaccines where you get a much more sustained level of antibodies,” she said.
