Another lockdown could be on the horizon in Israel with half of recently-Covid-infected adults having been fully vaccinated before they got sick.
That's according to the Wall Street Journal and the Epoch Times.
Israel's expert advisory panel made the announcement last Friday and renewed certain mask recommendations, such as indoor masking. In Israel, the vaccinated adults who got Covid-19 had received the Pfizer version of the shot.
According to Epoch Times, earlier this month, nearly 4,000 fully vaccinated people in Massachusetts tested positive for Covid-19 and "on April 30, the CDC reported that some 10,626 breakthrough cases were reported in 46 states and territories." Breakthrough cases are where fully vaccinated people still end up infected with Covid-19.
Scientists hoped that Covid-19 vaccines would be effective in variants of Covid-19, which are mutations that occur naturally with viruses and were always expected with Covid-19. However, the vaccine effectiveness against variants may be limited. CDC and vaccine makers are studying the medical landscape to find out more.
