Exclusive| Moderna says in talks with several countries for rollout of Covid-19 vaccine

Moderna is enrolling 30,000 people as part of its phase-3 clinical trial, which is expected to be completed later this month and if all goes to plan, it may launch the vaccine by year-end.


Moderna Therapeutics that has emerged as the frontrunner in the race for a coronavirus vaccine is in talks with several countries for a possible rollout of the much-awaited jab, the US-based biotech company has told Moneycontrol.

The company said it was committed to “equitable access” to its vaccine candidate but declined comment on a possible plan for a launch in India or a tie-up with Indian companies to distribute the vaccine.

“We are in ongoing conversations with a number of countries around the world for Moderna’s investigational vaccine mRNA 1273,” Moderna spokesperson said in an email to queries about its plans for India.

“At this stage, we cannot disclose any further details,” the statement added.

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.

Spotlight is back on the company after the British drugmaker AstraZeneca earlier this week paused phase-3 clinical trials of its vaccine after suspected adverse reaction in a participant in the United Kingdom.

On September 10, Serum Institute of India, too, put on hold trials of AstraZeneca's vaccine, developed with the University of Oxford, in the country.

Drugmakers are racing to come out with a vaccine to contain the pandemic that has known to have sickened more than 28 million across the world and killed at least 904,000 people.

India, too, is seeing a surge in cases, with daily infections hovering close to 100,000-mark. The country now has at least 4.5 million confirmed Covid-19 cases, including 76,271 deaths.

“We remain committed to making sure we have timely, affordable and equitable access for our candidate vaccine to ensure a global response to the pandemic,” it said.

COVID-19 Vaccine Watch: All you need to know about the vaccine’s manufacturing and pricing

Since it was founded in 2010, Moderna had worked to build the industry's leading mRNA technology platform, the Massachusetts-based biotech company said.

Moderna became one of the first companies to take a Covid-19 vaccine into a phase III clinical trial, which tests the safety and efficacy of a drug or a jab.

The company, which was little known until it announced a successful phase-1 trial earlier this year, is in the process of enrolling 30,000 people for the Phase-3 trial, expected to be completed later this month.

The results will be announced in October and if successful, a rollout by year-end.

Moderna said earlier that smaller volumes of its experimental vaccine have been priced at $32-$37 (Rs 2, 354-2,722) per dose.

Silent on India

Moderna remains tight-lipped on India, which has the second-highest number of Covid-19 cases in the world and is also one of the biggest vaccine-makers. 

Companies such as AstraZeneca, Novavax, Johnson & Johnson have announced partnerships with Indian companies such as Serum Institute of India and Biological E to manufacture and distribute vaccines in India. 

Moderna’s method of producing vaccine differs from conventional manufacturers and it may not require the expertise that Indian companies offer.

The company’s vaccine uses genetic material called messenger RNA to instruct body’s cells to make viral proteins that induce an immune response.

The vaccines that are in the market now contain weakened or inactivated disease-causing viruses or proteins called antigens, which work by mimicking the infectious microbe. Once the vaccine is injected, it activates the body’s immune system and issues instructions to produce antibodies.

Conventional vaccines are complex to produce. The organism or the protein of choice has to be cloned first, which is time-consuming and expensive.

The advantage of mNRA method is that it helps to develop and produce vaccines rapidly at scale. These vaccines are safer as they don't use any live or inactivated viruses.

Moderna earlier said it was on track to deliver around 500 million doses per year, and possibly up to 1 billion doses per year from 2021 because of the company’s US manufacturing capabilities and strategic collaboration with Switzerland-based Lonza.

Recently, the company also announced a tie-up with US-based Catalent for large-scale, commercial fill-finish manufacturing of mRNA-1273 for the US and with ROVI of Spain for other countries.

Moderna, which has never brought a vaccine in the market, has received nearly $1 billion from the US government under its Operation Warp Speed programme that is funding several coronavirus vaccine candidates.
