Dahil buong mundo ay abala sa pagpuksa ng COVID-19, laging laman ng balita ang pagpapabakuna laban sa sakit na ito. Ayon sa Bloomberg, ang Estados Unidos ang nangunguna sa dami ng mga nabakunahan. Pumapalo sa halos 2.5 milyon ang natuturukan ng COVID-19 vaccine sa U.S. kada araw.

Simula nang inumpisahan ng Pilipinas ang vaccination drive nito n’ung March 1, higit sa 240,000 ang nabakunahan nang mga Pilipino. Ngunit bukod sa mabagal na pagdating ng mga vaccine, hadlang sa malawakang vaccination ang kawalan ng tiwala ng mga Pilipino sa vaccine. Ayon sa isang survey, 46% ng mga Pilipino ay hindi papayag mabigyan ng COVID-19 vaccine kahit na napatunayan itong ligtas at epektibo.

 

Kasaysayan ng Bakuna  

Pinaniniwalaan na ang English physician na si Edward Jenner ang unang nagsagawa ng matagumpay na pagpapabakuna. Pagkatapos niyang turukan ng smallpox virus ang isang bata, nagkaroong ang pasyente ng immunity sa nasabing sakit. Nang nagkaroon na ng mass vaccination, tuluyan nang naiwaksi mula sa mundo ang small pox noong 1979.

Ayon sa Centers for Disease Control and Prevention (CDC), mahalaga ang childhood vaccines o ‘yung mga bakunang ibinibigay sa mga sanggol at bata sa pag-iwas sa sumusunod na mga sakit:

 

 

Ang mga bakuna ay nagbibigay proteksyon, hindi lang sa indibiduwal, kungdi pati rin sa buong komunidad.

 

Ano ang Herd Immunity?

Inilalarawan ng World Health Organization (WHO) ang herd immunity bilang indirektang proteksyon laban sa isang nakahahawang sakit. Maaaring magkaroon ng immunity ang isang populasyon mula sa pagpapabakuna o dati nang pagkakasakit. Dahil posibleng mabiktima ng COVID-19 nang higit sa isang beses, inirerekomenda ng WHO ang pagpapabakuna laban dito upang makamit ang herd immunity.

 

Para hindi dapuan ng matinding COVID-19 ang malaking bahagi ng populasyon, isinasagawa ng mga bansa ang malawakang vaccination. Herd immunity rin ang layunin ng pamahalaan ng Pilipinas kaya inanunsyo nito ang planong mabakunahan ang 70 milyong Pilipino sa loob ng isang taon.

 

COVID-19 Vaccination Plan sa Pilipinas

Noong Pebrero, inilabas ng Inter-Agency Task Force for the Management of Emerging Infectious Diseases (IATF-EID) ang priority list o ‘yung pagkakahanay ng mga mababakunahan.

Ayon sa Philippine National Deployment and Vaccination Plan for COVID-19 Vaccines, nakakalap na ang pamahalaan ng ₱82.5 billion. Ilalan ito sa pagbili ng mga vaccine at iba pang mga gastusin sa pagbabakuna.

Nabanggit ni Department of Finance (DOF) Secretary Carlos Dominguez III na posibleng umabot sa ₱1,300 ang pagbabakuna sa bawat indibiduwal. Dagdag pa niya, mga 57 milyong Pilipino ang makikinabang sa ₱75-bilyong pondong inilaan ng pamahalaan sa pamimili ng mga vaccine. Ang natitirang populasyon ay paggagastusan ng mga LGU (local government unit) at pribadong sektor. Sa ilalim ng Bayanihan to Recover as One Act, pumirma ng kontrata ang lokal na pamahalaan, LGU at mga 300 pribadong kumpanya upang bumili ng 17 milyong dosis mula sa  British pharmaceutical company na AstraZeneca. Ayon kay Joey Conception, ang Presidential Adviser for Entrepreneurship, kalahati ng mga dosis na bibilhin ng pribadong sektor ay ibibigay sa  gobyerno, habang ang kalahati ay mapupunta sa mga empleyado ng mga kumpanya.

Base sa tinatayang datos ng paglago ng populasyon mula sa Philippine Statistics Authority, bumuo ang pamahalaan ng three-year vaccination plan mula 2021 hanggang 2023. Inaasahan na sa 2022, maaari nang mabakunahan ang mga 16 years old pababa, habang meron nang COVID-19 vaccine para sa mga sanggol sa 2023. Ang mga binakunahan ngayong 2021 ay bibigyan pa ng booster shots sa susunod na mga taon.

Pagkamit ng Herd Immunity

Kahit hindi pa alam ng WHO ang eksaktong porsyento ng isang populasyon na dapat mabakunahan upang makamit ang herd immunity, layunin ng pamahalaan ang mabigyan ng COVID-19 vaccine ang 70 milyong mga Pilipino ngayong 2021. Pero dalawang dosis ang kailangan para makumpleto ang pagpapabakuna— ibig sabihin, 140 milyong dosis ang dapat maiturok ngayong taon.

 

 

Base sa mga bilang na ito, dapat bilisan ng pamahalaan ang pagbabakuna para magkaroon ng herd immunity sa bansa—lalo na’t kailangang kailangan na ito ng ating ekonomiya.

Matagal pang haharapin ng bansa ang pandemya, at hindi pa natin alam kung kailan ito matatapos. Ngunit isang bagay ang maliwang: hangga’t hindi pa nababakunahan ang 70 milyong mga Pilipino, kailangan ng ibayong pag-iingat ngayong tumataas muli ang mga kaso ng COVID-19 sa bansa.

Tumatakbo ang oras, pero habang wala pang bakuna ang karamihan ng mga Pilipino, dapat sundin ang mga hakbang upang masiguro ang pansariling kalusugan at kaligtasan. Sa ganitong paraan pa lang natin maiiwasan ang sakit na patuloy na dumadagdag sa 2 milyong bilang na namamatay sa buong mundo.

With the whole world racing to beat the pandemic, COVID-19 vaccinations are at the top of the global news pile. According to Bloomberg, the United States tops the list of having the most vaccinations so far at the rate of over 2 million doses per day. 

Since the start of the Philippines’ vaccination drive last March 1, the latest tally of total vaccinations is now over 114,000. Besides the delayed arrival of vaccines, another hurdle the country’s mass vaccination faces is the Filipinos’ reduced confidence in vaccines. According to a recent survey, 46% of Filipinos are unwilling to get inoculated against COVID-19 even if the vaccine was proven safe and effective.

 

A Brief History of Vaccines

English Physician Edward Jenner is widely recognized to have made the first vaccination in 1796. After inoculating a child with smallpox virus, the vaccinee developed an immunity to the disease. Mass immunization following the development of the smallpox vaccine led to the disease’s global extermination in 1979.

The Centers for Disease Control and Prevention (CDC) acknowledges the crucial role of childhood vaccines in preventing the following diseases: 

 

For communicable diseases, vaccines act as extra protection for the body and the entire community. To get this kind of protection, a community must achieve herd immunity.  

 

What is Herd Immunity?

Herd immunity or population immunity is defined by the World Health Organization (WHO) as the “indirect protection from an infectious disease that happens when a population is immune either through vaccination or immunity developed through previous infection.” WHO makes it clear that it supports herd immunity against COVID-19 through vaccination.

This is achieved through mass vaccination, enabling majority of the population to be immune to the disease. Scientists are still researching how much of the population needs to be inoculated for herd immunity against COVID-19 to take place. In the Philippines, the government announced its plans to vaccinate 100% of its adult population or about 70 million Filipinos.

With vaccination costs pegged at ₱1,300 per individual according to Department of Finance (DOF) Secretary Carlos Dominguez III, around 57 million Filipinos will benefit from the nearly ₱75-billion funds allocated by the government for vaccine acquisition. The remaining individuals are to be covered by the local government units (LGUs) and the private sector. Under the Bayanihan to Recover as One Act, the national government, local government units (LGUs) and about 300 Philippine companies signed an agreement with British pharmaceutical company AstraZeneca to procure 17 million vaccine doses. In this article, Presidential Adviser for Entrepreneurship Joey Concepcion said that half of the vaccine doses will be given to the national government, while the remaining half are for the companies’ workforce.

With population projections from the Philippine Statistics Authority, the government developed a three-year vaccination plan from 2021 to 2023. The roadmap assumes that by 2022, those 16 years old and below may be allowed to take the vaccine, and that by 2023, newborns can be inoculated against COVID-19. Those who’d taken the shots in 2021 will be given booster shots in the succeeding years.

Achieving Herd Immunity

Though WHO emphasizes that “the proportion of the population that must be vaccinated against COVID-19 to begin inducing herd immunity is not known,” the Philippine government’s goal of vaccinating 70 million Filipinos this 2021 aims to achieve herd immunity. Because each vaccination requires two doses, 140 million vaccine doses need to be rolled out in a year.

 

Based on such figures, the government needs to ramp up its vaccination drive to achieve herd immunity, and enable the country to recover both from the health and economic crises. 

The country’s battle against the pandemic is still unfolding but one thing remains clear: until the crucial number of 70 million have not been vaccinated, Filipinos need to be on their toes as cases continue to surge. 

Time is of the essence, but with majority having no means for vaccination yet, basic health and safety measures are still the strongest defense against this disease which continues to add to the global death toll of over 2 million.
