Hello, I am Dr. Elmer Huerta and this is your daily dose of information about the new coronavirus, information that we hope will be useful to take care of your health and that of your family. Today we will answer some questions that we have been asked on our Twitter account @DrHuerta.

Questions about the coronavirus vaccine

Hi Erika, of course I do. Transplanted people are more susceptible to complications from covid-19, therefore they must protect themselves with the vaccine.

The idea is that if a transplant recipient is vaccinated annually against the flu, something they should always do, they can also be vaccinated against covid-19.

Excellent question, Daniel. Some reports indicate that the US Food and Drug Administration would not require large phase 3 studies, but only small safety and immunity studies. That is, a kind of phase 1.

Hello, Pilar, excellent question. It is estimated that around 10% of people may have persistently positive molecular tests a few weeks after they have overcome COVID-19.

A South Korean study showed that these people cannot infect others because the reason the test comes out positive is because the test is so sensitive that it reports any trace of the virus present in the secretions as positive.

Excellent question, Miguel. In a bad year, the flu vaccine is approximately 20% effective, and in a good year it is 60%.

Compare that with the effectiveness of covid-19 vaccines, which almost all pass 75%.

Very good question Richard, but the truth is that I don’t have a firm answer.

We could theoretically assume that if the vaccine was able to fully protect the person from an infection by the new coronavirus, it could not colonize it, and therefore the person will not produce antibodies.

But on the other hand, if the person is infected by a variant resistant to the neutralizing antibodies produced by the vaccine, the person would be reinfected and develop the disease.

Excellent question, Mario. It all depends on how quickly the B1351 variant discovered in South Africa spreads around the world.

On the positive side, AstraZeneca has already said that it is working on a new version of its vaccine, which could be distributed by COVAX.

Hello Ebert, the efficacy of the Sinovac CoronaVac vaccine is in the midst of controversy.

While in Brazil it has been calculated at 50.38%, in Turkey it has been calculated, although in a small sample of volunteers, at 91%.

Hi Eddie, welcome to the Fact versus Fiction family. According to the US Centers for Disease Control and Prevention, people who are going to get the Pfizer vaccine and have food or drug allergies can get the vaccine.

Only those who had a severe reaction after receiving an intramuscular injection would not be able to receive it.

Hello Camila. Achondroplasia, which is the most common type of dwarfism, is not a contraindication to receiving any vaccine.

Your family member should be vaccinated.

Questions about the treatment and sequelae of the coronavirus

Hello, Julio, I would love to give you some recommendations, but unfortunately there is no home remedy to improve the defense system.

What I can tell you is that, knowing that the system is made up of cells and proteins called antibodies, a healthy and balanced diet will cause you to produce those elements that constitute the defense system.

Hello Jorge, as we heard in the episodes of August 22 and January 13, it is possible that there may be sequelae on the skin due to covid-19. Some of them present as hives.

I suggest you see a general practitioner or dermatologist for a diagnosis and follow-up on your mom.

Hello, Always. Unfortunately, there is no specific treatment against this childhood complication of Covid-19. As we said in the May 14 episode, the disease should only receive supportive treatment in the hospital.

Fortunately, despite the spectacular symptoms, the disease has a very low mortality rate.

Questions about contagion

Good question, Pizzito. The studies are not conclusive. Some indicate that the immunity is short, around 90 days, others indicate that it could be 8 months.

I think we should wait longer to study and learn more about the disease.

Hi, Ivonne. According to a review in the journal Nature, although it is true that contagion through surfaces exists, it is very rare compared to contagion through the respiratory tract, through aerosols.

Therefore, it would not be necessary to do everything you say. It would only be enough to wash your hands well when you get home.

It is difficult to determine that data, Emilio. Some laboratory experiments have calculated that an aerosol can stay up to three hours in a hermetically sealed cylinder.

I think that in real life, the duration of an aerosol in a closed space will depend on the ventilation of the place and the concentration of the virus.

That is why if you have someone with COVID-19 isolated in their room, both the patient and the caregiver should always wear a mask and the windows should be open.
