Quotes from 3 Israeli news articles:
The Health Ministry reported Monday that the effectiveness of the coronavirus vaccine against the Delta variant is less than its effectiveness against the earlier variants.
"The Health Ministry is constantly monitoring the effectiveness of the coronavirus vaccines", the ministry said in a statement,
"From an epidemiological analysis of public health services at the Health Ministry, starting June 6, there is a decrease in the benefit of the vaccine in preventing infection to 64% and in preventing symptomatic infection to 64%. The decline was observed simultaneously with the spread of the Delta variant in Israel.
Pfizer Chief Scientific Officer Mikael Dolsten said the recently reported dip in the vaccine's effectiveness in Israel was mostly due to infections in people who had been vaccinated in January or February. "The Pfizer vaccine is highly active against the Delta variant," Dolsten said in an interview, according to Reuters. But after six months, he said, "there likely is the risk of reinfection as antibodies, as predicted, wane."
Coronavirus patients who recovered from the virus were far less likely to become infected during the latest wave of the pandemic than people who were vaccinated against COVID, according to numbers presented to the Israeli Health Ministry.
Health Ministry data on the wave of COVID outbreaks which began this May show that Israelis with immunity from natural infection were far less likely to become infected again in comparison to Israelis who only had immunity via vaccination. More than 7,700 new cases of the virus have been detected during the most recent wave starting in May, but just 72 of the confirmed cases were reported in people who were known to have been infected previously – that is, less than 1% of the new cases.
