As of August 10, Malaysia relaxed some COVID-19 restrictions under the National Recovery Plan for individuals who are fully vaccinated against COVID-19. Malaysia’s National Security Council will publish Standard Operating Procedures here.
The Malaysian authorities consider an individual "fully vaccinated" against COVID-19:
• 14 days after the second dose of Pfizer, Astrazeneca, or Sinovac
• 28 days after one dose of Johnson & Johnson or Cansino
(Update) Home Quarantine for Vaccinated Travelers
Per the Malaysian Prime Minister's August 8 speech, fully vaccinated Malaysians and foreigners who have a residence in Malaysia, including permanent residents, and MM2H visa holders returning from overseas may serve their quarantine at home, subject to strict requirements including mandatory electronic monitoring. The Malaysian government has not yet shared a formal written SOP specifying whether long term pass holders other than MM2H pass holders are eligible for home quarantine or clarifying the process for requesting home quarantine.
