What do we know about breakthrough COVID-19 cases? Experts break down the science – CBC
Infections among fully vaccinated expected to increase, but usually as milder infections
Aug 26, 2021
As COVID-19 cases rise through parts of the country, experts expect the number of infections among fully vaccinated people will increase with them. But that doesn’t mean the vaccines have stopped working.
Cases among fully vaccinated individuals — dubbed breakthrough infections if they occur at least two weeks following a second dose — are rare, experts say, even against the more transmissible delta variant of the virus.
And the chance a fully vaccinated person would get seriously ill or die following a COVID-19 infection is even less likely, they add.
“To date, the vaccines are doing exactly what we would expect them to be doing,” said Dr. Isaac Bogoch, an infectious disease physician with the University of Toronto.
