Explanation:

Recently the United States has announced the support for waiving Intellectual Property (IP) protection for Covid-19 vaccines.

• The decision is a breakthrough in India and South Africa's attempts to get World Trade Organisation (WTO) member countries to agree to such a waiver to fight the pandemic equitably.
• Intellectual property rights (IPR) are the rights given to persons over the creations of their minds: inventions, literary and artistic works, and symbols, names and images used in commerce. 
• They usually give the creator an exclusive right over the use of his/her creation for a certain period of time.

India is a member of the World Trade Organisation and committed to the Agreement on Trade Related Aspects of Intellectual Property (TRIPS Agreement).

• The TRIPS Agreement sets the minimum standards of protection for copyrights and related rights, trademarks, geographical indications (GIs), industrial designs, patents, integrated circuit layout designs, and undisclosed information. 
• It establishes minimum standards for the enforcement of intellectual property rights (IPRs) through civil actions for infringement, actions at the border, and at least in regard to copyright piracy and trademark counterfeiting, in criminal actions.

Hence only statements 1&3 are correct.
