Tejashwi Yadav demands parole for Lalu, says he is vulnerable to COVID-19

Though his doctor was put under quarantine after the report surfaced, Lalu’s son Tejashwi Yadav, who is currently heading the party, took to Twitter to highlight his concerns.

Fearing exposure to novel coronavirus infection, Lalu Prasad Yadav's son has said his father's life is in jeopardy after a patient lodged at the Rajendra Institute of Medical Sciences (RIMS) in Ranchi tested positive for COVID-19.

This patient was being treated in the same ward as Lalu and was also being attended to by the same doctor.

Though his doctor was put under quarantine after the incident came to light, Tejashwi Yadav, who is currently heading the party, tweeted his concerns.

He wrote:

Meanwhile, another post concerning Lalu’s parole was shared from RJD’s official Twitter account, which claimed that the government is “deliberately” not granting the veteran leader parole.

Lalu was jailed after he was found guilty in a corruption case but has spent most of his sentence at RIMS Ranchi due to multiple age-related illnesses.

COVID-19 Vaccine

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.
