New smart visa improved to make life easier for digital nomads in Thailand

Since Thailand launched its mass Covid-19 vaccination campaign in late February, the Chinese-made Sinovac vaccine and the AstraZeneca vaccine, made in partnership with the University of Oxford in the UK, have been used to vaccinate residents of Thailand.

Local company Siam Bioscience is currently producing the AstraZeneca vaccine and the first batch made in Thailand is expected to launch next month.

Vaccine type

AstraZeneca: A recombinant vaccine from a modified chimpanzee adenovirus.

This is a harmless, weakened adenovirus that commonly causes the common cold in chimpanzees. The adenovirus vaccine vector, known as ChAdOx1, was chosen as a suitable vaccine technology for a vaccine against SARS-CoV-2 because it has been shown to generate a strong immune response from a single dose. in other vaccines. It has been genetically modified so that it is impossible for it to develop in humans. – Australian Department of Health

Sinovac: An “inactivated” vaccine, using inactivated virus particles to produce an immune response, a traditional approach to vaccines and the same technology used to produce vaccines for influenza and polio.

The World Health Organization says the vaccine is made by inactivating or killing the virus using chemicals, heat or radiation.


Studies are still ongoing for both vaccines, while further studies on the AstraZeneca vaccine have been reported. In Thailand, a recent study from the Chulalongkorn Center of Excellence in Clinical Virology at the Faculty of Medicine found that both vaccines were effective.

According to the university study …

  • 99.49% of Sinovac recipients developed antibody responses 4 weeks after their second injection.
  • 97.26% of AstraZeneca recipients developed antibody responses 4 weeks after their first injection.

Thailand initially used the Sinovac vaccine for people aged 18-59 due to limited research for the 60+ age group. Thai health officials recently announced that recent studies show Sinovac to be safe and effective for healthy adults over the age of 60.

World travel

A dilemma for many expats living abroad, or those who wish to travel in the future, is which Covid-19 vaccine to get, as some are not recognized by other countries.

Sinovac and AstraZeneca have both met the World Health Organization criteria for safety and efficacy.

Some countries may not recognize some vaccine passports, although international tourism is still in its infancy and the proposed regulations are constantly changing.

Thailand recognizes vaccines that are approved by the World Health Organization or the Thai government.

The European Union is considering reopening tourism to American travelers, but they may need a vaccine approved by the European Medicines Agency.
