The World Health Organization has the honour to transmit, in accordance with the
“International Nonproprietary Names for Variant COVID-19 Vaccine Active Substances”
document available on WHO website: https://www.who.int/publications/i/item/inn-21-520
(INN Working Document 21.520 April 2021), the following list of proposed international
nonproprietary names (prop. INN) which has been published by the World Health Organization
on the WHO website at https://www.who.int/teams/health-product-and-policy-standards/inn/inn-
lists.
– p.INN list 129 – COVID-19 (special edition)
It would be appreciated if this communication could be forwarded to the appropriate patent
and trade-mark office and to any other organization dealing with the introduction of
nonproprietary names for pharmaceutical substances. Any comments that may be made, or
notifications of a conflict between proposed names and existing proprietary rights, should be
addressed to the INN Programme, World Health Organization, 1211 Geneva 27, within
two weeks following the publication of the above-mentioned list on the WHO website,
i.e. no later than 14 July 2023.
The selection of international nonproprietary names by the World Health Organization for
use in all Member States presents many difficulties. It would therefore be appreciated if this
were borne in mind when it is contemplated to exercise the right to raise objections.
Furthermore, the World Health Organization would be grateful if, in the interest of public
health and pursuant to the procedure referred to in the first paragraph of this communication, the
above-mentioned list of names could be granted protection in Member States during the period
they are under consideration by the World Health Organization as international nonproprietary
names.
