Covid-19 vaccination is also mandatory for individuals based on their professions and the infection risks associated with them as determined by the Ministry of Health.
"Exemptions are granted to those who cannot get vaccinated for medical reasons as permitted by the health authorities," it said.
The sub-decree also stipulates penalties for failure to receive Covid-19 jabs.
"Each institution shall first issue a warning to those who avoid vaccination ... and subject them to administrative measures or legal action should they continue to avoid getting vaccinated," it said.
