FILIPINOS who received their full dose of COVID-19 vaccines between 2021 and 2023 retain significant protection against the newly emerged NB.1.8.1 variant, according to Health Secretary Teodoro Herbosa.
This reassurance comes amidst reports of the variant, nicknamed “Nimbus,” causing a characteristic “razor-blade” sore throat alongside other common COVID-19 symptoms.
Secretary Herbosa stated that data suggests previous vaccinations remain effective, offering continued protection to the approximately 78.4 million fully vaccinated Filipinos (70% of the population) as of June 2024.
While the Department of Health (DOH) hasn’t yet detected NB.1.8.1 within the country, the Research Institute for Tropical Medicine has been tasked with conducting genome sequencing on recent COVID-19 samples to confirm its presence and monitor its spread.
Despite NB.1.8.1’s classification by the World Health Organization (WHO) as a variant under monitoring with a low global public health risk, a recent increase in cases was observed in the Western Pacific region, including the Philippines, along with the Americas, Europe, and Southeast Asia.
The WHO maintains that currently available COVID-19 vaccines are expected to remain effective against symptomatic and severe disease caused by this variant.
The DOH, however, remains vigilant, with the Epidemiology Bureau closely monitoring COVID-19 case numbers in the Philippines.
A potential surge in cases is anticipated to coincide with the rainy season, a period that typically sees an increase in influenza-like illnesses. The combination of these factors necessitates continued monitoring and preparedness.
