Delivery plan

The national government planned to roll out its vaccination program around February expecting the delivery of Pfizer's vaccines sourced from the COVAX facility and the first batch of Sinovac's vaccines, consisting of 50,000 doses.^[7] The delivery of Pfizer's vaccines was delayed due to documentary issues.^[8]

The government planned to start a full rollout or mass vaccination for the general populace around late 2021.^[9]

Regulatory approval

Under normal circumstances, drugs and vaccines are reviewed for approval by the Food and Drug Administration (FDA) under a period of six months. President Rodrigo Duterte to fast-track the government's medical response to the pandemic signed an executive order on December 2, 2020, which allowed the FDA to grant emergency-use authorization (EUA) to COVID-19 vaccines and treatments.^[10] An EUA for a particular vaccine would authorize the government to buy said vaccine and allow to use the same for the vaccination program. An EUA would not authorize the commercial use of such vaccines or consent the use of the vaccine for personal use.^[11]

The EUA approval process by the FDA is covered under FDA Circular No. 2020-036.^[12][13]

An EUA granted for COVID-19 vaccine or drug remains valid if it fulfills three conditions:^[13]

• Based on the totality of evidence 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.
• The known and potential benefits of the drug or vaccine...outweigh the known and potential risks, if any.
• There is no adequate, approved, and available alternative to the drug or vaccine.

The EUAs validity ends one year from the lifting of the public health emergency status declared in response to the pandemic or one year from the date it was registered if a COVID-19 drug or vaccine gets fully registered with the FDA.^[13]

Among the conditions for a vaccine manufacturer to secure an EUA in the Philippines is to obtain prior EUA in its country of origin or other countries with a "mature" regulator.^[14] No manufacturer would be allowed to obtain an EUA in the Philippines first. For the purpose of the FDA's EUA approval process, the following foreign regulators are considered as "mature":^[13]

• Therapeutic Goods Administration (Australia)
• Pharmaceuticals and Medical Devices Agency (Japan)
• Ministry of Food and Drug Safety (South Korea)
• Health Canada
• Health Sciences Authority (Singapore)
• Swiss Agency for Therapeutic Products (Switzerland)
• Medicines and Healthcare products Regulatory Agency (United Kingdom)
• Food and Drug Administration (United States)
• European Medicines Agency (European Union)

Rollout

The Philippines' vaccination officially began on March 1, 2021, shortly after the arrival of the first batch of vaccines from Sinovac. Prior to the official roll-out, a dry run was conducted to ensure that the vaccines, especially temperature-sensitive ones, would be rolled-out with minimal problems.^[15]

In February 2021, the Food and Drug Association recommended against the usage of Sinovac vaccines for health care workers due to its low efficacy rates in trials on health care workers in other countries. It has recommended its usage instead to the vaccine to the working population and military personnel.^[16][17]

The National Immunization Technical Advisory Group (NITAG) on February 26 has approved the use of the Sinovac vaccine to health care workers.^[18] Health care workers are still allowed to not take the vaccine and wait for a more effective vaccine.^[19] Philippine General Hospital (PGH) employees demanded for a better vaccine and an increase with their hazard pays.^[20]

At a press conference, Presidential Spokesperson Harry Roque stated that health care workers can refuse the Sinovac vaccine and wait for the vaccines from Pfizer–BioNTech, Moderna, and Oxford–AstraZeneca while still being prioritized but other prioritized groups shall only get what is available in their locality.^[21]

The rollout for the Philippines' national vaccine program began on March 1, 2021, shortly after the arrival of 600,000 doses of Sinovac's vaccine.^[22] Philippine General Hospital director and doctor Gerardo Legaspi officially became the first recipient of a COVID-19 vaccine in the country.^[23] The initial batch will cover around 50,000 military personnel and 250,000 health workers.^[24] As of March 3, 2021, vaccinations has been limited to Metro Manila and to health workers.^[25] However, select government officials were vaccinated in a bid to boost confidence on the vaccine.^[26]

On March 6, 2021, Oxford–AstraZeneca, under the COVAX facility, began the rollout. Health workers who refused Sinovac's vaccines were prioritized.^[27][28]

In May 2021, the rollout of vaccines from two manufacturers began. The rollout of the Sputnik V vaccines began on May 3 with five cities of Metro Manila; namely Makati, Manila, Taguig, Parañaque, and Muntinlupa.^[29] The deployment of Pfizer started on May 12, beginning in two cities in Metro Manila (San Juan and Makati).^[30] On June 30, 2021, the Moderna vaccine began its rollout in Metro Manila including San Juan.^[31] On July 20, 2021, the Janssen vaccine began being rolled out in Tacloban.^[32] On August 12, 2021, Vaccine Czar Carlito Galvez Jr. announced that recipients of the Sputnik V vaccine as their first dose can receive the AstraZeneca vaccine as their second dose provided that the shipment of Sputnik V is delayed due to logistical issues.^[33]

Vaccination of minors began in mid-October 2021. At that time, emergency use authorizations for the use of Moderna and Pfizer vaccines for minors (ages 12–15 for Pfizer; age 12-17 for Moderna) has been granted.^[34]

To hasten the immunization program, the government announced that it was holding "National Vaccination Days" on November 29 until December 1. November 29 and December 1 will be special working days.^[35] Initially targeted to immunize 15 million people, it was reduced to 9 million due to logistics issues surrounding the syringes for Pfizer vaccines.^[36]

Recognition of vaccination certificates

On July 4, 2021, the Inter-Agency Task Force for the Management of Emerging Infectious Diseases (IATF) has permitted domestic travel within the Philippines for fully vaccinated individuals that have been vaccinated with a COVID-19 vaccine under the Emergency Use Listing (EUL) by the World Health Organization (WHO) or have been granted an emergency use authorization (EUA) or a compassionate special permit (CSP) issued by the Food and Drug Administration (FDA).^[40] The same rules applies for fully vaccinated international travelers from countries and territories deemed as "low-risk" and can receive a reduced quarantine period of seven days.^[41]

On October 8, 2021, the IATF introduced revised guidelines that fully vaccinated travelers from "low-risk" (green list) and "moderate-risk" (yellow list) jurisdictions can receive a reduced facility-based quarantine up to five days upon presentation of a national digital certificate issued by a foreign government with a reciprocal agreement with the Philippines.^[42]

On October 13, 2021, the IATF subsequently permitted the entry of fully vaccinated travelers from "low-risk" (green list) countries and jurisdictions to skip facility-based quarantine provided there is a presentation of negative RT-PCR test result within 72 hours before departure from their country. This policy was later to the presentation of a negative RT-PCR test result within 48 hours before departure from their country.^[43][44]

The Philippines presently recognizes the vaccination certificates issued by the following countries: Albania, Armenia, Argentina, Azerbaijan, Australia, Austria, Bahrain, Belgium, Brazil, Brunei, Cambodia, Canada, Chile, Colombia, Czech Republic, Denmark, Ecuador, Egypt, Estonia, France, Georgia, Germany, Greece, Hong Kong, India, Indonesia, Iraq, Ireland, Israel, Italy, Japan, Kazakhstan, Kuwait, Macau, Malaysia, Maldives, Malta, Myanmar, Monaco, the Netherlands, New Zealand, Oman, Palau, Papua New Guinea, Peru, Portugal, Qatar, Samoa, Singapore, Slovenia, Spain, Syria, Switzerland, South Korea, Sri Lanka, Thailand, Timor–Leste, Tunisia, Turkey, the United Arab Emirates, the United Kingdom, the United States, Uruguay, and Vietnam.^{[45][46][47][48][49][50]}

Booster shots

The Health Technology Assessment Council (HTAC), the independent advisory council issued its recommendation for the administering of a third dose of the COVID-19 vaccine as a booster shot with a priority towards health care workers and other priority groups.^[51]

Booster shots were rolled for frontline healthcare workers on November 16, 2021.^[52] Similarly, the IATF has approved the administration of booster shots for Overseas Filipino Workers who are set for deployment within four months provided their second dosage was taken six months prior.^[53] Senior citizens and immunocompromised persons were rolled out on November 22, 2021. These groups can choose their preferred vaccine brand in comparison to their primary series.^[54]

On December 3, 2021, the Philippine Department of Health announces the expansion of the booster shot program stating all adults aged 18 years and above can receive additional booster shots at least six months from the primary series or three months after receiving the single-dose Janssen COVID-19 vaccine.^[55]

Due to the threat of the SARS-CoV-2 Omicron variant, the Department of Health announced on December 22, 2021, the shortening of the interval of the booster doses for all adults aged 18 years and above at three months from their primary series or two months after receiving the single-dose Janssen vaccine.^[56]

On January 14, the Philippines has secured 17 million doses of coronavirus disease 2019 (COVID-19) vaccines from British-Swedish pharmaceutical and biopharmaceutical firm AstraZeneca.^[113]

A shipment of 487,200 Oxford–AstraZeneca COVID-19 vaccines under COVAX's facility arrived in the country on March 4, 2021.^[114] An additional shipment of 38,400 doses arrived in the country on March 7, totalling a number of 525,600 doses from COVAX's facility.^[115] 2 million additional doses arrived in the country from COVAX's facility on May 8.^[116][117]

The first batch of procured Oxford–AstraZeneca vaccine, consisting of 1,150,800 doses, arrived on July 16.^[118]

Sinovac

Plans to secure 36 million doses from China's Sinovac have also been subjected to scrutiny in Congress due to its reported efficacy rate. The efficacy rate of the Sinovac vaccine has varied by country; Turkey has reported an efficacy rate of 91%^[119] while Brazil has reported an efficacy rate of 78%.^[120] The Department of Health said that Sinovac's vaccine satisfy the World Health Organization standards of at least 50 percent efficacy rate while the FDA pointed out that Sinovac is yet to publish an official and published scientific report on their vaccines efficacy rate and that the clinical trial for the vaccine is conducted in different countries and the efficacy rate per country will vary.^{[84][121][122]} Following the approval for emergency use authorization on February 22, the first batch of Sinovac vaccines, consisting of 600,000 doses, from China's donation to the country arrived on February 28.

The first batch of procured vaccines by the government reached the Philippines on March 29 came from Sinovac with previous received vaccines coming from donations.^[123]

On August 24, the government bought additional 10 million doses from Sinovac.^[62]

Black market

In January 2021, during the time when only the Pfizer–BioNTech vaccine had an emergency use authorization, it was reported that an alleged black market of smuggled vaccines from China has established itself in the Philippines. The demand for the vaccines is particularly high for Chinese nationals in the country, especially those employed by Philippine Offshore Gaming Operators (POGOs). The doses are reportedly sold at inflated prices, considerably more expensive than the standard price of the same vaccines in China.^[151]

In late March 2021, the FDA released an advisory cautioning the public against fake vaccines and that vaccines which had emergency use authorization are not authorized to be sold commercially. Although as of that date, there are no reports yet of fake vaccines proliferating in the country as per the FDA.^[152]

Line jumping

The DOH reported in March 2021 that a number of individuals had jumped the line to get the vaccine, becoming vaccinated despite being otherwise ineligible to do so.^[153] These include several local government officials, prompting the Department of the Interior and Local Government (DILG) to issue show cause orders against them to explain why they were vaccinated,^[154] and actor Mark Anthony Fernandez, who was vaccinated despite not belonging to a priority group for the vaccine.^[155] Fernandez, for his part, claimed that he had underlying health conditions that otherwise made him eligible.^[156]

The issue has raised the concerns of the Commission on Human Rights,^[157] and has also led to the WHO warning the Philippine government that it risks losing access to its share of vaccines provided by COVAX if the practice continues.^[158]

A number of suggestions were floated to address line jumping, with Senator Franklin Drilon urging the government to ramp up the country's vaccine supply,^[159] and Representative Precious Hipolito, who represents the second district of Quezon City, filing a bill that would amend the Philippines' COVID-19 vaccination law to criminalize the practice.^[160]

Vaccination of the Presidential Security Group and President Duterte

Health Secretary Francisco Duque III administering the Sinopharm BIBP vaccine to President Rodrigo Duterte in May 2021

On May 3, 2021, President Rodrigo Duterte received his first dose of the Sinopharm BIBP vaccine despite the latter not receiving an EUA from FDA. The FDA only issued a one-time compassionate special permit (CSP) for 10,000 doses of the vaccine for the PSG.^[175]

But due to public outrage, President Duterte apologized for taking the vaccine that has not been authorized by the FDA for emergency use and asked the Chinese Embassy to take back its donation.^[176]

Non-recognition of vaccine certificates by Hong Kong

Foreign Affairs Secretary Teodoro Locsin Jr. announced the Government of Hong Kong will not honor the proof of vaccination issued by local government units and the Bureau of Quarantine in the Philippines due to a lack of a central registry. This was after several Overseas Filipino Worker (OFWs) bound for the territory were reported to have been refused entry due to non-recognition of their vaccine certificates.^[177][178]

As an interim solution, the Department of Health confirmed that all outbound travelers would use the International Certificate of Vaccination (ICV) issued by the Bureau of Quarantine as an official proof of vaccination for international travel better known as the "yellow card".^[177]

On August 22, 2021, the Department of Labor and Employment announced that the Government of Hong Kong will permit the entry of fully vaccinated Filipino workers into the territory upon the presentation of the International Certificate of Vaccination issued by the Bureau of Quarantine (BOQ) beginning on August 30, 2021.^[179]
