Daily cases in Israel are expected to reach record highs in the coming three weeks.
Nachman Ash, director-general of the health ministry, said that it was now possible that herd immunity could be reached as a result of the significant level of infections.
However, he said it was not desirable to reach this point through infections, and that vaccinations remained the best path to protecting people.
“The [infection] numbers will have to be very high in order to reach herd immunity,” he told Israeli radio.
“This is possible but we don’t want to reach it by means of infections, we want it to happen as a result of many people vaccinating.”
Herd immunity is reached when a high proportion of the population are either vaccinated or have been infected and recovered, making it difficult for infectious diseases to spread.
Salman Zarka, the head of the health ministry’s coronavirus task force, has warned that herd immunity is far from guaranteed, not least because experience over the past two years has shown that some Covid-19 patients who recovered were later reinfected.
Around 60 per cent of Israel’s 9.4 million population are fully vaccinated, which means they have either received three doses or have had their second dose recently.
Hundreds of thousands of those eligible for a third jab have so far not taken it, though.
Israel, which rolled out its vaccine effort at the world’s fastest rate, and was the first to start delivering third doses this summer, announced last month that it would offer a fourth dose of the coronavirus vaccine to people over the age of 60.
On Sunday, the country approved the use of Merck’s molnupiravir antiviral pill for Covid patients over 18 years of age.
In November, the UK became the first country in the world to approve molnupiravir, which has been shown to reduce hospitalisations and deaths by around 30 per cent in a clinical trial.
Around 1.3 million coronavirus cases have been documented in Israel since the start of the pandemic. But between 2 and 4 million people may well be infected by the end of January, when the Omicron wave could subside, according to Eran Segal, a data scientist at the Weizmann Institute of Science and an adviser to the government.
Over the past 10 days, daily infections have more than quadrupled. Severe cases have also climbed but at a far lower rate, rising from about 80 to around 100.
