Which treatments work and which don’t, according to Harvard?

As the coronavirus pandemic advances around the world, scientists have gradually recognized some of the treatments and medications capable of reducing the impact of the virus on the human body and allowing recovery without the need for hospitalization.

Methods used during a flu, such as resting, staying hydrated and taking medications to control fever and body aches, are some of the most common and effective that help with Covid-19, Harvard points out, as long as the virus does not attack severely.

On the other hand, for stronger infections, scientists have been researching and testing medical therapies such as remdesivir, plasma, and antiviral drugs that can aid in the recovery of hospitalized patients.

But how effective are these treatments?

Investigational treatments and others more approved for use they do not mean a definitive cure, they only reduce symptoms and support recovery.

Here we leave you with six treatments listed by Harvard that have been related to the coronavirus and its effectiveness.

Monoclonal antibodies

The US Food and Drug Administration (FDA) has granted an emergency use authorization for this treatment, also known as bamlanivimab, to treat non-hospitalized adults and children 12 years of age and older with mild to moderate symptoms who recently tested positive for Covid and who are at risk of developing severity or being hospitalized.

The treatment works, according to the FDA, but not in hospitalized patients or with oxygen therapy as it can make their condition worse.

Convalescent plasma

The blood of the people who recover from the virus they contain antibodies that they produce to fight the coronavirus on their own.

Plasma can only be donated by patients who tested positive, had no symptoms for 14 days, tested negative at the time of donation, and had high levels of antibodies in their plasma. A patient and a donor must have compatible blood.

This method has already been used with measles, polio, chickenpox and the SARS for years, so it is believed to be safe.

However, not much is known about its efficacy on Covid due to its aggressiveness and resistance. In one study, plasma was found to help reduce the risk of death in patients at risk of severe Covid.

Antiviral treatments

In October the FDA approved the drug remdesivir to treat the virus in adults and children 12 years of age and older who weigh at least 88 pounds and have been hospitalized.

According to clinical trials, remdesivir accelerates moderately recovery time.


A recent report indicates that corticosteroid dexamethasone decreases the risk of death in very sick hospitalized patients with Covid.

Previous research, Harvard says, has not been as meticulous as would be expected, but taking the drug in the early stages of illness is known to weaken the natural defense system and allow the virus to thrive in the body.

“What might make more biological sense is to administer dexamethasone when laboratory studies suggest that the immune system is overloaded after the amount of virus in the body has started to decline,” experts say.

Vitamin D

A recent study suggests that vitamin D protects the body from infection and development of severe symptoms.

According to specialists, the vitamin provides protection in two ways: it helps boost the body’s natural defense against viruses and bacteria, or it helps prevent a inflammatory answer exaggerated, contributing to serious illness in some patients.

Vitamin C

Some critically ill patients have received high intravenous doses of this vitamin to accelerate their recovery, but there is no clear scientific evidence that it is a 100 percent effective treatment.

There is also no evidence that the vitamin prevents infection. Experts recommend taking care of standard dose of vitamin C Since in excess it can cause nausea, cramps and an increased risk of kidney stones.
