Article II, Section 15 of the 1987 Constitution of the Republic of the Philippines mandates the State to protect and promote the health of the people and instill health consciousness among them. The State is further mandated under Article XIII, Section 11 of the Constitution to adopt an integrated and comprehensive approach to health development which shall endeavor to make essential goods, health and other social services available to all the people at affordable cost.

Under Republic Act No. 3720, or the “Food, Drug and Cosmetic Act,” as amended by Executive Order No. 175, s. 1987, and Republic Act No. 9711, or the “Food and Drug Administration Act of 2009,” the Food and Drug Administration (FDA) was created to establish and maintain a drug regulatory system to ensure the purity, safety, efficacy and quality of drugs and vaccines in the country. Section 21 of Republic Act No. 3720, as amended, provides that any new drug should have an authorization from the FDA based on an application containing full reports of investigations to show whether or not such drug is safe, efficacious and of good quality for use based on clinical studies, prior to manufacture, sale, importation, exportation, distribution or transfer thereof.

Pursuant to Proclamation Nos. 922 (s. 2020) and 1021 (s.2020), the Philippines was declared under a State of Public Health Emergency, and a State of Calamity due to the COVID-19 pandemic.

Subsequently, Republic Act No. 11494 or the “Bayanihan to Recover as One Act” was enacted authorizing the President to suppress the COVID-19 pandemic through the procurement of drugs and vaccines.

Considering that no registered drug and vaccine exist for COVID-19 in the Philippines, the President of the Republic of the Philippines issued Executive Order (EO) No. 121 entitled “Granting Authority to the Director General of the Food and Drug Administration to Issue Emergency Use Authorization (EUA) for COVID-19 Drugs and Vaccines, Prescribing Conditions therefore and for other Purposes.” Said issuance gave authority to the Director General to issue an EUA, and established the conditions under which said authorization may be issued.

The FDA is hereby introducing the process for the issuance of EUA to sustain and strengthen the national preparedness for the COVID-19 public health emergency. The principles of regulatory reliance and recognition are adopted to accelerate the evaluation and approval process for EUA to ensure immediate access to drug products and vaccines for COVID-19.


This Circular aims to provide guidelines on the regulation of EUA for drugs and vaccines for COVID-19.


This Circular shall apply to the pharmaceutical industry and government entities such as the national procurer or health program implementors intending to apply for an EUA for drugs and vaccines for COVID-19, and shall pertain only to unregistered (anywhere in the world) drugs and vaccines for prevention, diagnosis and treatment of COVID-19 and granted an EUA by the National Regulatory Authority (NRA) of the country of origin or any other mature and established NRA as identified by FDA.


A. Emergency Use Authorization (EUA) – is an authorization issued for unregistered drugs and vaccines in a public health emergency. The EUA is not a Certificate of Product Registration (CPR) or a marketing authorization. The evaluation process of the product may be facilitated by reliance and recognition principles, but stricter conditions on the use and monitoring following authorization shall be imposed.

B. Drugs – as used in this issuance, refer to pharmaceutical products that pertain to chemical compounds or biological substances, other than food, intended for use in the treatment, prevention, or diagnosis of disease in humans or      animals, including the following:

1. Articles intended for use in the diagnosis, cure, mitigation, treatment, or prevention of disease in man,

2. Articles (other than food) intended to affect the structure or any function of the body of humans, and

3. Articles intended for use as a component of any articles specified in the foregoing clauses but do not include devices or their components, parts or accessories.

C. Recognition – shall refer to the acceptance of the regulatory decision of another trusted institution. It shall be based on evidence of conformity that the regulatory requirements of the reference regulatory authority are sufficient to meet the regulatory requirements of the relying authority.

D. Reliance – shall refer to the act whereby the NRA in one jurisdiction may take into account and give significant weight to assessments performed by another NRA or trusted institution, or to any other authoritative information in reaching its own decision.


A. The EUA shall only be issued and remain valid under all of the following conditions provided herein.

B. The applicant shall submit requirements to support the application for EUA.

C. The Center for Drug Regulation and Research (CDRR) and an Expert Panel shall review the application and provide recommendations on the COVID-19 drug or vaccine being applied for an EUA.

D. The Director General shall act on the application by either issuing the EUA or a Letter of Disapproval (LOD).

E. A COVID-19 drug or vaccine with issued EUA shall be subject to post authorization surveillance. Pharmacovigilance obligations and post-authorization commitments shall be imposed on the holder of the EUA. The pharmacovigilance obligations and post-authorization commitments by the holder of the EUA shall also be shared with the national procurer and health program implementors.

A flowchart of the process for the issuance of the EUA for drugs and vaccines is provided in Annex “A” of this Circular.


A. Conditions for Issuance of the EUA

The EUA shall only be issued and remain valid only when all of the following circumstances are present:

  1. Based on the totality of evidence available, including data from adequate and well- known controlled trials, it is reasonable to believe that the drug or vaccine may be effective to prevent, diagnose, or treat COVID-19;
  1. The known and potential benefits of the drug or vaccine, when used to diagnose, prevent, treat COVID-19, outweigh the known and potential risks of the drug or vaccine, if any; and
  1. There is no adequate, approved and available alternative to the product for diagnosing, preventing or treating COVID-19.

The last condition is deemed present when there exists no registered drug or vaccine in the country for diagnosing, preventing or treating COVID-19.
