Philippines on the Path to Endemicity: Insights into its Covid-19 Response

Strategic Insights

— 2 min read

The Philippines has recently seen an unprecedented surge in new Covid-19 cases, with daily counts reaching 600,000 in South Korea and nearly 300,000 in Germany. In contrast, the country reported under 1,000 cases per day since March 2, 2022. Despite high vaccination rates in many countries experiencing large case numbers, the Philippines has maintained a low positivity rate of less than 5% since the end of February 2022. This suggests adequate testing, and a combination of factors, including mask mandates, diverse vaccine types, early boosting, and heterologous boosting, have contributed to the country's low case numbers.

Key Takeaways:

  • The Philippines has maintained a low positivity rate of less than 5% since the end of February 2022, indicating adequate testing.
  • The country's low case numbers are attributed to a combination of factors, including mask mandates, diverse vaccine types, early boosting, and heterologous boosting.
  • The Philippines was one of the first countries to adopt boosters at three months from the second vaccine dose, resulting in low numbers of severe diseases and subsequent hospitalization.
  • The country's use of eight different vaccine brands, including inactivated vaccines (Sinovac, Sinopharm), which have more antigen epitopes on top of the spike protein, has increased resilience against variant mutations.
  • Heterologous boosting may be more effective against variants compared to homologous boosting, as evidenced by the country's low numbers of severe diseases and hospitalizations.
  • The Philippines' Omicron spike in January 2022 was driven by the BA.2 sublineage, unlike most countries, which were affected by BA.1.
  • The country's ability to delay its earlier Delta spike with preemptive lockdowns has resulted in hybrid immunity from breakthroughs from August 2021 being relatively fresh.

Statistics:

  • The Philippines has under 1,000 cases per day since March 2, 2022.
  • The country's positivity rate has been below 5% since the end of February 2022.
  • 86% of South Korea is fully vaccinated, and 63% are boosted.
  • 45% of Vietnam is boosted.
  • The Philippines was one of the first countries to adopt boosters at three months from the second vaccine dose.
  • The All-Experts Group of the Department of Health recommend offering boosters to all fully-vaccinated persons above 18 years old.
  • Many healthcare workers, elderly people, and those with comorbid conditions received their booster shots in a timely manner.

  • The World Health Organization's guidelines on adequate testing during the acute phase of the pandemic.
