Jakarta, CNBC Indonesia – Israel’s Ministry of Health said the Covid-19 vaccine made by Pfizer-BioNTech was only 39% effective against the delta variant coronavirus in the country. Even so, this vaccine can still provide strong protection against severe symptoms.
The vaccine’s efficacy figure is down from an earlier estimate of 64% two weeks ago. Israel previously conducted a study based on an unspecified number of people between June 20 and July 17.
This Israeli report contradicts data from the UK which found that the Pfizer-BioNTech vaccine was 88% effective against the coronavirus variant. CNBC International.
According to data published Thursday (7/22/2021), Pfizer-BioNTech’s two-dose vaccine is still doing very well in preventing terminally ill people, showing 88% effectiveness against hospitalization and 91% effectiveness against severe illness.
The report from Israel is likely to reinforce arguments from drug manufacturers that people will eventually need to get booster vaccine shots to protect against the new variant of the coronavirus.
In early July 2021, Pfizer said immunity from its two-dose vaccine was starting to wane, and now plans to seek clearance from the United States Food and Drug Administration for a booster dose.
However, federal officials say fully vaccinated Americans do not need additional injections at this time.
In a statement, Pfizer said it remained confident its two-dose regimen protected against the coronavirus and its newer variants. It said a third dose might be helpful after analysis of phase three studies showed decreased efficacy against symptomatic infections after four to six months.
“Preliminary data from the third dose of the current vaccine suggest that a booster dose administered at least 6 months after the second dose results in high neutralization titers against wild-type and Beta, which are 5 to 10 times higher than after the two main doses,” said Pfizer.
The delta variant is now available in more than 104 countries. Israel alone now has more than 859,000 infections and more than 6,000 deaths, according to data menurut Worldometers.
