The Ministry of Health of India has published revised guidelines for international arrivals in a tweet by Dr. Mansukh Mandaviya, Minister for Health and Family Welfare; Chemicals and Fertilizers, Government of India. 

The official tweet indicates that in addition to uploading RT-PCR negative results taken 72 hours before travel, there is also the option of uploading a copy of the certificate showing completion of the COVID-19 vaccination provided by a country on a reciprocal basis.

The new guidelines stipulate that vaccinated travellers to India from countries such as Qatar will not need to undergo a pre-travel RT-PCR test starting 14 February 2022.

A RT-PCR certificate is required by some airlines.

As part of the announcement, "countries considered "at-risk" were removed from the list and others were added. Consequently, given countries deemed 'at-risk' are not required to provide samples at port of arrival or wait for results. International travelers in all countries were randomly picked at random to represent 2% of the total. It is no longer necessary to perform RT-PCR testing on 8th day and submit that data to the Air Suvidha portal."

Note: A RT-PCR certificate is required by certain airlines. If you intend to travel, you should check with your airline for the latest requirements.
