Nachman Ash had said single Pfizer/BioNTech dose was less effective than expected
Israel’s health ministry has moved to row back on comments by the country’s coronavirus tsar, who suggested single doses of the Pfizer Covid-19 vaccine had not given as much protection against the disease as had been hoped.
The remarks by Nachman Ash, reported first in the Israeli media earlier this week, drew widespread attention for appearing to suggest that the vaccine was less effective than expected after a single dose had been administered as the country recorded record cases and extended its lockdown earlier this week.
