THE PHARMACEUTICAL INDUSTRY is pouring resources into the growing political fight over generic coronavirus vaccines.

Newly filed disclosure forms from the first quarter of 2021 show that over 100 lobbyists have been mobilized to contact lawmakers and members of the Biden administration, urging them to oppose a proposed temporary waiver on intellectual property rights by the World Trade Organization that would allow generic vaccines to be produced globally.

Pharmaceutical lobbyists working against the proposal include Mike McKay, a key fundraiser for House Democrats, now working on retainer for Pfizer, as well as several former staff members to the U.S. Office of Trade Representative, which oversees negotiations with the WTO.

Several trade groups funded by pharmaceutical firms have also focused closely on defeating the generic proposal, new disclosures show. The U.S. Chamber of Commerce, the Business Roundtable, and the International Intellectual Property Alliance, which all receive drug company money, have dispatched dozens of lobbyists to oppose the initiative.

The push has been followed by a number of influential voices taking the side of the drug lobby. Last week, Sen. Thom Tillis, R-N.C., released a letter demanding that the administration “oppose any and all efforts aimed at waiving intellectual property rights.” Howard Dean, the former Democratic National Committee chair, has similarly criticized the proposal, echoing many of the arguments of the drug industry.

Currently, only 1 percent of coronavirus vaccines are going to low-income countries, and projections show much of the world’s population may not be vaccinated until 2023 or 2024. In response, a coalition of countries, led by India and South Africa, have petitioned the WTO to temporarily suspend intellectual property rights on coronavirus-related medical products so that generic vaccines can be rapidly manufactured.

The waiver requests a suspension of IP enforcement under the Trade-Related Aspects of Intellectual Property Rights, or TRIPS, treaty. If granted, local pharmaceutical plants could be granted compulsory licenses to produce coronavirus vaccines without the threat of being sued by the license holder.

The proposal has gained traction globally, with hundreds of members of the European Parliament, dozens of American lawmakers led by Sen. Bernie Sanders, I-Vt., and increasingly vocal voices in the public health community expressing support.
