Why It’s Hard to
Make Vaccines: Explained.
With the high demand for the COVID-19 vaccine, its
rollout has undergone massive delays around the globe.
Here are some reasons why vaccine production
has taken longer than expected.
Creating large amounts
of mRNA takes time, University of Pennsylvania’s Dr. Drew Weissman
says, “prior to this, nobody made a billion doses
... or even a million doses of mRNA.” .
Production can’t begin
without raw materials, If even one item is missing, production has to be
delayed “and that capacity will be lost forever,”
says Moderna CEO Stéphane Bancel.
Batches sometimes fall short, Working with biological ingredients
leaves room for variability and can
result in fewer doses than expected.
Quality assurance takes time, Every vaccine is produced under
strict rules, including inspections
and testing throughout the
process, which may cause delays
