Explained | Why the latest aid from US doesn't include COVID-19 vaccines or ingredients

After more than a week of frantic diplomatic talks, the Biden administration has decided to provide crucial medical help for India. Even though the US has identified specific sources of raw materials required for Indian manufacturers of Covishield, it doesn’t say which is the raw material and how much will be available.

Late on Sunday, the United States promised to soon dispatch excess rapid testing kits, Personal Protective Equipments (PPEs), ventilators and key drugs to India.

The mega bilateral aid package will land even as the Biden administration continues to rebuff India's request for critical vaccine doses which the US currently stockpiles and bans the export of key chemical components needed for vaccine manufacturing. The US has also not clarified whether it will be able to provide Remdesivir doses, the demand for which has shot up over the past two weeks in India.

In an official statement, the White House announced that US National Security Advisor Jake Sullivan had spoken to his Indian counterpart, National Security Advisor Ajit Doval, and that the “United States is working round-the-clock to deploy available resources and supplies” to India.

Ministry of External Affairs (MEA) officials say this is not expected to be the last development on the matter as the second wave gains pace in India and the need for faster vaccination strengthens and both governments will continue to negotiate on critical help.

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.
