Drugmakers&nbsp;on Thursday said US President Joe&nbsp;Biden's support for waiving&nbsp;patents of COVID-19&nbsp;vaccines could disrupt a fragile supply chain, and that, rich countries should instead share more generously with the developing world.

Biden&nbsp;on Wednesday threw his support behind waiving intellectual property rights for COVID-19&nbsp;vaccines, angering research-based pharmaceutical companies.

If adopted by the World Trade Organisation, the proposal would invite new manufacturers that lack essential know-how and&nbsp;oversight from the inventors to crowd out established contractors, the International Federation of Pharmaceutical Manufacturers and Associations (IFPMA) said.

"I have heard many (vaccine&nbsp;makers) talking about 'our resources are stretched, our technicians are stretched'," IFPMA Director General Thomas Cueni told Reuters. He warned of a possible free for all if "sort of rogue companies" were allowed to become involved.

Vaccine&nbsp;developers echoed his comments that waiving intellectual property rights was not a solution.

"Patents are not the limiting factor for the production or supply of our&nbsp;vaccine. They would not increase the global production and supply of&nbsp;vaccine&nbsp;doses in the short and middle term," said Germany's BioNTech, which aims to supply up to three&nbsp;billion doses together with Pfizer this year.

BioNTech said it took more than a decade to develop its&nbsp;vaccines manufacturing process and replicating it required experienced personnel and a meticulous technology transfer, among several other factors beyond&nbsp;patents.

Another German company CureVac, which hopes to release trial results on its messenger ribonucleic acid (mRNA)&nbsp;vaccine&nbsp;as early as this month, said&nbsp;patents were not to blame for supply bottlenecks.

"Since mRNA technology has emerged as the key technology in the fight against COVID-19, the world now needs the same raw materials in unfathomable amounts. The biggest problem is how to coordinate this," a spokeswoman said.

IFPMA's Cueni said the real bottlenecks were trade barriers, in particular the US Defense Production Act (DPA).

The DPA is a decades-old US law that prioritised procurement orders related to US national defence, but it has been widely used in non-military crises, such as natural disasters.

Cueni said the way to kickstart low-income countries' vaccination campaigns, was for rich countries to donate&nbsp;vaccine, rather than widen eligibility to young and healthy people at home.

Moderna, which on Thursday reported quarterly results, said waiving intellectual property rights would not help to increase the supply of its&nbsp;vaccines in 2021 and 2022.

The US drugmaker said last year it would not enforce its&nbsp;vaccine&nbsp;patents. CureVac said on Thursday it would also not enforce its&nbsp;patents during the pandemic and that it knew of no other developer that would.

Italy's ReiThera which is in late-stage tests on an experimental COVID-19&nbsp;vaccine was also critical of&nbsp;patent&nbsp;waivers.

"There is proprietary know-how that has to be transferred by the owner. And then there is the problem with process materials, which at the moment have delivery times of almost a year," ReiThera's chief of technology Stefano Colloca said.

In contrast to the industry reaction, the GAVI&nbsp;vaccine&nbsp;alliance, which co-leads the COVAX dose-sharing programme with the WHO and faces major supply constraints, welcomed&nbsp;Biden's support for waiving intellectual property rights.
