The HTAC recommends the DOH financing and inclusion of Sinopharm in the Philippine National Deployment and Vaccination Plan for COVID-19 (NDVP) for the general population aged 18 years and above.


COVID-19 Vaccines under Emergency Use Authorization (EUA)

The Food and Drug Administration (FDA) issues Emergency Use Authorization (EUA) for vaccines and drugs during public health emergencies which allows a shorter period for effective and efficient review of health technologies so that they can become available to affected populations. Before the EUA is issued, regulatory agencies consider quality, safety, and efficacy of the technology.

Following the issuance of an EUA, a positive HTAC recommendation means that the National Immunization Program can finance the implementation of the technology and PhilHealth can include it in the COVID benefit package

The three versions of Sinopharm were issued an EUA on the following dates (

  • Sinopharm (Beijing) – 10 September 2021
  • Sinopharm (Wuhan) – 19 August 2021
  • Sinopharm (Hayat-Vax) – 07 October 2021


What is the recommendation of HTAC for Sinopharm as part of homologous primary series vaccination?

The HTAC recommends the DOH financing and inclusion of Sinopharm in the Philippine National Deployment and Vaccination Plan for COVID-19 Vaccines for the general population aged 18 years and above, given that it has passed the safety, efficacy and other criteria of HTAC and provided that there is sufficient budget to cover its implementation after pending supply negotiations in 2022. 

Based on current available evidence, Sinopharm has the following characteristics for use in the general population aged 18 years and above:

    • Is efficacious in preventing symptomatic COVID-19 and is likely to provide protection against severe COVID-19
    • Has potential in reducing a significant number of symptomatic infections, assuming sufficient vaccine coverage;
    • Safe, although more data is needed to establish its long-term safety
    • Can reduce the out-of-pocket expenses due to averted costs of isolation and treatment from COVID-19 infection
    • Affordable and feasible in terms of vaccine implementation
    • Possess most of the characteristics desired by key stakeholders, according to national surveys and based on conducted focus group discussions
  • Does not aggravate health inequities due to non-stringent logistic requirements


Is Sinopharm affordable for the implementation among the general population in 2022?

The price of Sinopharm offered to the Philippine government is within the global market price range, and is lower compared to  those in low to middle income countries where it is available, according to the Department of Finance (DOF) and the UNICEF COVID-19 Vaccine Market Dashboard. Based on the costing analysis of HTAC, Sinopharm is considered affordable, although its procurement and implementation will still depend on the available budget for 2022.

  • General side effects: general weakness, fatigue, lethargy, headache, tenderness, malaise, fever, shivering, general body pain, pruritus, nausea, dizziness, constipation, runny nose, dyspnea, arthralgia

There should be continuous safety surveillance and monitoring of all adverse events especially severe allergic reactions and adverse events following vaccination.


What precautions should be considered before administering the vaccine?

  • The vaccine must not be administered intravenously, intradermally, or subcutaneously.
  • Supervision and appropriate medical treatment should always be available to treat any anaphylactic reactions following immunization
  • For those with concurrent fever, acute illness or those currently experiencing acute chronic disease attacks, severe chronic disease, thrombocytopenia and any coagulation dysfunction, for immunocompromised persons or those receiving immunosuppressive therapy, vaccination may be subject to physician advice and supervision.

  • The vaccinee should remain under medical supervision for at least 30 minutes after vaccination. Vaccination clinics should keep epinephrine and other drugs for first aid in case of severe allergic reactions.
  • Check the packaging container, label, appearance, and validity period before use. The product cannot be used if the glass container has cracks or there is any spot, stain or

scratch on the outer surface, or the label is unclear, or the product expires, or the appearance is abnormal.


How should the vaccine be prepared before administration?

Preparing the vaccine

  1. Assess recipient status. Screen for potential contraindications and precautions, and review their vaccination history.
  2. Observe aseptic techniques. Perform hand hygiene before preparing the vaccine, between recipients, when replacing gloves*, and at any other time hands become soiled.
  3. NEVER use expired vaccines. Check expiration dates before use. 
  4. Inspect the vaccine for precipitates and shake to disperse. NEVER use vaccines with foreign particles, or those stored in cracked bottles or in poorly marked containers.
  5. Keep the vaccine between 2°C and 8°C. Do not freeze the vaccine.

*Gloves are not recommended unless the vaccinator will likely come in contact with potentially infectious bodily fluids or open wounds. Where worn, follow aseptic technique. Perform hand hygiene and switch gloves between recipients.


How should the vaccine be administered?

Make sure to wear complete and correct personal protective equipment (PPE) before administering the vaccines.

  1. Choose the correct equipment and needle size. Make sure to use a new, sterile needle and syringe for every injection.
  2. Extract 0.5 mL of the vaccine into the prepared syringe (0.5 mL per dose).
  3. Bring the dose of vaccine from the preparation area to the administration area immediately following preparation. 
  4. Immediately administer the vaccine by intramuscular (IM) injection into the deltoid muscle. 
  5. The vaccine must be administered in two doses, on Day 0 and Day 21-28.
