That is more about patent protection, than vaccines. Most vaccines are made up government contract at non-commercial rates,, but like fleet discounts for cars. It keeps the production ticking over making others drugs cheaper, also the patents on the vaccines have long expired. Considering a new drug often costs $500m+ to develop and get approval its a high stakes business. With the limited 10-20 year patent, they want it extended.
