Dahil sa paglaganap ng Delta variant, mahirap na umanong makamit ang herd immunity sa ating bansa, ayon sa isang eksperto.
Dagdag pa rito, nahahawahan pa rin ng COVID-19 maging ang mga indibidwal na kumpleto na ng bakuna.
Dahil dito, dapat itaas na raw ang target na bilang ng populasyon na babakunahan kontra COVID-19, ayon kay Dr. Rontgene Solante.
“Because of this Delta variant, that’s the game changer now, that all countries are recalibrating their target of vaccination rate, not necessarily herd immunity, but vaccinating the whole population,” ani Solante.
“For example, Israel is vaccinating 70 percent. Initially they said they were able to achieve herd immunity. But now since there were breakthrough infections even at 70 percent, they are now targeting 100 percent vaccination and even giving booster to the elderly. My opinion, very difficult to achieve herd immunity with the virus that’s highly transmissible and at the same time can evade immunity or protection against many of these current vaccines,” dagdag niya.
Matatandaang kamakailan lamang ay sinabi ng World Health Organization na laganap na ang mas nakahahawang Delta variant sa bansa.
Ayon naman kay Health Secretary Francisco Duque III, posibleng makamit ng Pilipinas ang herd immunity bandang unang quarter ng 2021, kung saan target mabakunahan ang 77 milyong Pilipino.
“Supply permitting and assuming that there will be about 500,000 or 600,000 doses jabbed per day, the conservative estimate is… we might be able to achieve herd immunity sometime second month of the first quarter. Mga first quarter po ‘yan, mag-spill over po sa first quarter 2022,” ayon kay Duque.
Masasabing naabot na ang herd immunity kung nabibigyan ng proteksiyon mula sa virus maging ang mga hindi bakunado, sa pamamagitan ng pagbabakuna ng malaking bahagi ng populasyon.
