The COVID-19 Situation and Prevention Centre in Ratchaburi province announced today (Saturday) that a woman, who was inoculated against COVID-19 on March 18th, tested positive for the virus a week later.

The 29-year old is a fresh seafood vendor at the Kitti Market, in Bang Khae district of Bangkok, where a cluster of infections was first identified over a week ago.

According to her timeline, disclosed by the COVID-19 Situation and Prevention Centre:

  • March 10th-12th, she stayed at home in Muang district of Ratchaburi and did not go to the market, which was temporarily closed.
  • March 13th, she returned to the market, after undergoing a saliva test, with the test result to be texted to her smartphone.
  • March 14th-17th, she stayed at home in isolation, waiting for the test result.
  • March 18th, she returned to Kitti Market to be vaccinated. After inoculation, she drove, non-stop, back to Ratchaburi.
  • March 19th, she stayed at home in self-isolation.
  • March 20th, health officials escorted her to a quarantine facility in Ratchaburi, after finding out that she used to work at the Kitti Market.
  • March 21st-25th, she was in quarantine in Ratchaburi.
  • March 26th, she underwent another test, was told that she is infected and was admitted to the provincial hospital.

According to the US Centers for Disease Control and Prevention (CDC), however, it typically takes a few weeks for the body to develop immunity after vaccination, adding “That means it’s possible a person could be infected with the virus that causes COVID-19 just before or just after vaccination and still get sick. This is because the vaccine has not had enough time to provide protection.”
