The government is considering “heterologous vaccination” for fully vaccinated individuals who are up for their third dose of COVID-19 vaccine to boost immunity, said the country’s vaccine czar.

Local officials should double their efforts in convincing their unvaccinated constituents to get COVID-19 shot, President Rodrigo Roa Duterte said on Monday, warning uncooperative officials that they could be held accountable under the guidelines if they fail to do their job.

In keeping with the Filipino tradition to visit the graves of their dearly departed loved ones during the Undas season, Presidential Spokesperson Secretary Harry Roque Jr. reminded the public of the protocols and guidelines to be followed, which were the same as the ones adopted last year.
