Explainer | Singapore coronavirus case shows vaccination doesn’t rule out infection. What does that mean?
- US Centres for Disease Control and Prevention said in April that of the 2,479 vaccinated people in a study, three had confirmed coronavirus infections
- In Japan, a hospital worker who had completed the vaccination regimen was confirmed to be infected on April 11
On Sunday, the first such infection in Singapore was reported by the Ministry of Health (MOH). The 23-year-old male Indian national had received both required doses of the Covid-19 vaccination on January 25 and February 17. Similar cases around the world have been reported before.
The US Centres for Disease Control and Prevention (CDC) said in April that of the 2,479 vaccinated people in a study, three had confirmed coronavirus infections after they were fully vaccinated. In Japan, a hospital worker who had completed the vaccination regimen was confirmed to be infected on April 11.
In Singapore over the past three months, MOH recorded at least three separate cases of people who tested positive for the virus after their first dose of the vaccine.
For those three cases, the ministry said it was possible for an individual to be infected just before or just after vaccination, since it typically takes a few weeks for an individual to build up immunity after taking the shots.
For the latest fully vaccinated case, MOH said this is “a reminder that it is possible for vaccinated individuals to get infected”.
