Many recovered COVID-19 patients suffer from heart problems, lung diseases: Report

These health problems could be owing to the damage to the small vessels caused by COVID-19 that leads to excessive clotting during the course of the disease.

Many recovered COVID-19 patients are suffering from heart problems and lung diseases after beating the novel coronavirus infection.

After recovering from COVID-19, some of the patients come to doctors with reduced heart function and heart attack or even stroke, Dr Yatin Mehta, critical care specialist at Medanta Hospital, was quoted as saying in a Hindustan Times report.

According to the report, these health problems could be owing to the damage to the small vessels caused by COVID-19 that leads to excessive clotting during the course of the disease.

COVID-19 disease is said to be attacking the endothelial cells that line the blood vessels, leading to clotting across the body of the patients, the report suggested.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
