Reacting to Ash’s note of caution, the Israeli Ministry of Health said “the comments of the Israeli Covid-19 commissioner regarding the effect of the first dose of the vaccine were out of context and, therefore, inaccurate,” according to a BBC report on Thursday.

Ash’s comments came after thousands of people tested positive despite being jabbed.

The ministry said that the full protective impact of the vaccine is expected to be seen only after the second dose is also administered.

It is well-known that a single dose of the Pfizer Covid-19 vaccine is not expected to provide full protection against the disease, although some countries like the UK have delayed giving the second dose in a bid to maximise the number of people given the initial dose.

A single dose of the Pfizer Covid-19 vaccine is about 52 per cent effective, according to the company, said the The Guardian report.

Health Minister Yuli Edelstein said that ever since the rollout of vaccinations began one month ago, the Jewish state had inoculated more than 2.2 million of its nine million inhabitants.

The vaccination drive happens at a time when  the country is in its third lockdown with infection rates still high. Since the pandemic began, more than half a million cases have been reported and 4,005 people have died in Israel. The rise in infections, despite the lockdown and vaccinations, has been attributed to virus mutations and disregard by some people of restrictions on assembly.
