To test or not to test
The Swedish Public Health Agency changes strategies for testing SARS-CoV-2
Previous decision: Not to test fully vaccinated because one was sure they were virus free.
New decision: To test everyone with symptoms because it has been shown that even fully vaccinated people can become infected and contagious.
Decisions under consideration: To test all of the vaccinated to evaluate the effect of the vaccines.
It should be noted, though, that many international experts strongly question the reliability of the PCR tests.
