Has it been determined if a fully vaccinated person can carry and/or spread the virus to others?
While the vaccine is highly effective, it does not guarantee immunity.
When a fully vaccinated person later gets COVID-19 that is called a “breakthrough case.” Harris says the number shows how effective the vaccine is.It is estimated that about 45% of people who contract COVID-19 will have no symptoms. This is one of the biggest challenges regarding the virus. It is clear that asymptomatic people may still have the ability to spread the virus to others.
