issued an open letter calling on Mr. Biden to support the proposed waiver.

On Capitol Hill, 10 senators including Bernie Sanders, independent of Vermont, and Elizabeth Warren, Democrat of Massachusetts, urged Mr. Biden to “prioritize people over pharmaceutical company profits” and reverse the Trump administration’s opposition to the waiver. More than 100 House Democrats have signed a similar letter.

a handful of governments, including those of Brazil and Thailand, bypassed patents held by the developers of antiviral drugs for H.I.V./AIDS in an effort to clear the way for lower-cost versions of the treatments.

H.I.V. drugs, however, involve a much simpler manufacturing process than the coronavirus vaccines, especially those using messenger RNA technology, which has never before been used in an approved product.

In a Twitter thread, Mr. Amin offered another example: In the 1980s, Merck and GlaxoSmithKline had developed recombinant hepatitis B vaccines and held a monopoly with more than 90 patents covering manufacturing processes. The World Health Organization recommended vaccination for children, but it was expensive — $23 a dose — and most Indian families could not afford it.

The founder of Shantha Biotechnics, an Indian manufacturer, was told that “even if you can afford to buy the technology your scientists cannot understand recombinant technology in the least,” Mr. Amin wrote.

But Shantha, he added, went on “to produce India’s first home-grown recombinant product at $1 a dose.” That enabled UNICEF to run a mass vaccination campaign.
