Moderna falters under Trump’s second term as vaccine scepticism grows

The biotech giant that soared during Operation Warp Speed now faces regulatory hurdles, political scepticism, and dwindling sales.

Moderna, once a cornerstone of the Trump administration’s Covid response, is facing a steep decline in fortunes as President Trump’s second term ushers in a stricter and more sceptical stance on vaccine development. Once hailed for its role in protecting millions with its mRNA Covid-19 shot, the biotech company now finds itself under pressure from regulators, lawmakers, and a shifting public health philosophy, the Wall Street Journal reported.

Narrow FDA approval highlights new regulatory reality

On Friday, the FDA approved Moderna’s latest Covid-19 booster — but only for a limited population: older adults and high-risk individuals between the ages of 12 and 64. The decision, far narrower than the company anticipated, is a sharp departure from earlier emergency authorizations and reflects new hurdles Moderna must clear under revamped FDA rules. The agency now requires randomized, controlled trials for new vaccine iterations, raising the bar for approval and slowing down development timelines.

The biotech is also feeling the pinch from the Department of Health and Human Services (HHS), which recently cancelled a $766 million contract awarded to Moderna under the Biden administration to develop mRNA-based vaccines for pandemic-level influenza. HHS cited both scientific and ethical concerns, calling the bird flu project “not scientifically or ethically justifiable.”

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.
