There’s no such thing as a vaccine generic in the way we think of generic pills. You can’t walk into a pharmacy and swap a brand-name COVID-19 shot for a cheaper version labeled ‘generic’-because it doesn’t work like that. Vaccines aren’t chemicals you can copy with a lab beaker and a formula. They’re living systems. Complex biological products made from viruses, cells, proteins, and intricate delivery systems like lipid nanoparticles. Copying them isn’t like copying a tablet. It’s like trying to rebuild a jet engine from a photo-without the blueprints, the specialized tools, or the trained engineers.
Why vaccines can’t be generic like pills
Traditional generic drugs are small-molecule compounds. Their chemical structure is fixed, easy to measure, and identical across manufacturers. The FDA lets companies prove they’re the same through bioequivalence tests-simple blood level checks. That’s the Hatch-Waxman Act, created in 1984. It opened the floodgates for cheap generics, and today, 90% of U.S. prescriptions are filled with them. Vaccines? They’re biologics. Made in living cells. Each batch is slightly different. Tiny changes in temperature, pH, or purification steps can alter how the immune system responds. There’s no shortcut. No bioequivalence test works here. Every new vaccine maker has to run full clinical trials, prove safety and effectiveness from scratch, and get a new biological license. That costs hundreds of millions. It takes years. And that’s why, despite decades of effort, there’s no true generic vaccine market.The manufacturing nightmare
Making a vaccine isn’t just science. It’s industrial engineering on a massive scale. You need biosafety level 2 or 3 labs. Ultra-cold freezers for mRNA vaccines at -70°C. Clean rooms the size of football fields. Specialized equipment you can’t just order off Amazon. And the raw materials? They’re even harder to get. For mRNA vaccines, you need lipid nanoparticles. Only five to seven companies in the world can make them. During the pandemic, the U.S. banned exports of these materials under the Defense Production Act. India, which produces 60% of the world’s vaccine volume, had to pause exports in April 2021 because it couldn’t get enough lipids or other critical inputs. Global supply dropped by half overnight. Even the Serum Institute of India-the largest vaccine maker on Earth, churning out 1.5 billion doses a year-struggled. They made the AstraZeneca shot for $3-$4 a dose. Western companies charged $15-$20. But Serum’s profit margin? Slim. Building one production line costs over $500 million. The math doesn’t add up unless you’re making billions of doses.Who makes the world’s vaccines-and who gets them
Six companies-GSK, Merck, Sanofi, Pfizer, Johnson & Johnson, and the Serum Institute-control about 70% of the global vaccine market. That’s $38 billion in 2020. And the distribution? Starkly unequal. At the start of the pandemic, high-income countries, making up just 16% of the world’s population, bought 86% of the first COVID-19 doses. Meanwhile, in the Democratic Republic of Congo, health workers got vials with expiration dates two weeks away-and no cold chain to store them. In April 2021, 83% of all COVID vaccines delivered to Africa went to just 10 countries. Twenty-three African nations had vaccinated less than 2% of their people. Africa produces less than 2% of its own vaccines. It imports 99%. India makes 70% of WHO’s vaccines-but exports 70% of its output. When India’s own second wave hit, it stopped exporting. The world felt it. That’s not a failure of goodwill. It’s a system built on dependency.
Why local production is so hard to build
You’d think countries like South Africa, Brazil, or Indonesia could just set up factories and start making vaccines. But it’s not that simple. The WHO launched a technology transfer hub in South Africa in 2021 with help from BioNTech. Two years later, they produced their first mRNA vaccine. But it took 18 months just to get the equipment. Finding the right bioreactors, filtration systems, and cold chain tools? Nearly impossible. Even with the tech, sourcing materials from the same five suppliers was a bottleneck. Building a vaccine plant takes 5 to 7 years and $200-$500 million. The African Union estimates it will take $4 billion and 20 years just to reach 60% self-sufficiency. And even then, who’s buying? Low-income countries can’t pay $10 a dose for pneumococcal vaccines. Gavi, the global vaccine alliance, negotiates prices down-but manufacturers still charge more than they should. The system doesn’t reward scale. It rewards monopoly.India: the world’s vaccine factory with fragile roots
India is the engine of global vaccine supply. It makes 40-70% of WHO’s DPT and BCG vaccines. 90% of its measles vaccines. And 14% of the U.S.’s generic drugs. But here’s the catch: 70% of the raw materials India uses to make vaccines come from China. That’s a single point of failure. When China shut down during early COVID, India’s production slowed. When the U.S. restricted lipid exports, India’s exports stopped. The country has 500 API manufacturers-but they’re not making the high-end materials for vaccines. They’re making the cheap stuff. The complex stuff? Still imported. Even the Serum Institute, the giant of the industry, operates on razor-thin margins. They’re not rich. They’re efficient. And they’re the only reason billions of people got vaccines at all. But if they ever face a supply shock, or political pressure, or a domestic surge-the whole system trembles.
What’s being done-and why it’s not enough
There are efforts. The Medicines Patent Pool works to license technology. The WHO’s hub in South Africa is a start. The U.S. FDA launched a pilot in 2025 to speed up approval for generic drugs made domestically-because they’re tired of relying on China and India for critical medicines. But these are drops in an ocean. The FDA’s pilot doesn’t even apply to vaccines. The South Africa hub can make 100 million doses a year. Global demand? Over 11 billion. That’s less than 1%. Dr. Chris Elias from the Gates Foundation says it plainly: “For vaccine equity, expand manufacturing.” But he also admits the capital requirements are terrifying. No private company will invest $500 million in a factory that might sell doses for $3 each. Governments won’t fund it unless they think they’ll get a return. And low-income countries? They’re stuck waiting.The path forward: it’s not about generics-it’s about power
We don’t need more generics. We need more manufacturers. More capacity. More control in the hands of countries that need vaccines, not just those that sell them. That means public funding for manufacturing in Africa, Latin America, and Southeast Asia. It means waiving intellectual property rights-not as a one-time fix, but as a permanent tool for global health security. It means building supply chains that aren’t controlled by five companies in three countries. The world learned this lesson the hard way. When a pandemic hit, the system didn’t just fail. It exposed how deeply unequal it was. The next time, we can’t afford to wait for charity. We need infrastructure. We need sovereignty. We need to stop treating vaccines like luxury goods-and start treating them like public goods.Because when a child in Lagos can’t get a polio shot because a lipid nanoparticle was shipped to New York instead-this isn’t a supply chain issue. It’s a moral failure.
