Health groups ask India to rescind Gilead's patents for COVID-19 drug remdesivir

But health access groups say the pacts mean cheaper forms of the drug may not become available in nations seen as non-profitable to the five drugmakers.

Two health advocacy groups have written to the Indian government asking it to rescind patents given to Gilead Sciences for the drug remdesivir so it can be distributed more fairly to coronavirus patients around the world, particularly in poorer nations.

Drug patents in India are an important issue as many countries depend on generic drugmakers to make and sell cheaper versions of critical drugs to them. Gilead’s three patents in India for remdesivir stem from 2009 when the drug was in development to treat Ebola.

Remdesivir is the only drug approved to treat COVID-19 patients after promising early trial results prompted U.S. regulators to grant emergency use authorisation on May 2.

To expand its access, Gilead said this week it had signed non-exclusive licensing pacts here with five generic drugmakers based in India and Pakistan, allowing them to make and sell remdesivir for 127 countries.

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.
