Oregon investigates FOUR cases of COVID in fully vaccinated people who
tested positive more than two WEEKS after getting their second shots

Four people in Oregon, who were fully immunized with the COVID-19 vaccine,
have tested positive for coronavirus

Two of the cases are in Yamhill County and the other two are in Lane County, and all the patients had mild to no symptoms

Both vaccines, from Pfizer-BioNTech and Moderna, are 95% effective, meaning 5% of all people will fall ill

Officials say there are bound to be more of these illnesses, which are known as 'breakthrough cases,' but most are expected to be mild

So far, 38.2 million Americans - 11.6% of the population - have received at least one dose while 14 million - 4.2% - have received both doseshttp://www.dailymail.co.uk/health/article-9263271/Oregon-investigating-FOUR-cases-COVID-fully-vaccinated-people.html
