This vaccine is effective in preventing the spread of Corona from person to person


Jakarta, CNBC Indonesia – A study in Israel proves that immunization with the Covid-19 vaccine made by Pfizer Inc and BioNTech SE can stop the spread of the corona virus from person to person.

As written Bloomberg On Sunday, a copy of a draft publication posted on Twitter by a company working with Israel’s Ministry of Health in preliminary observational analysis said the Pfizer-BioNTech vaccine was 89.4% effective at preventing laboratory-confirmed infections.

Separately, Israeli authorities on Saturday (20/2/2021) said the Pfizer-BioNTech vaccine was 99% effective in preventing deaths from the virus.

About 80% of SARS-CoV-2 cases in Israel during the study period, from January 17 to February 6, were caused by a more contagious strain. As of February 6, about 27% of people aged 15 years and over in Israel have been fully vaccinated against Pfizer-BioNTech.

According to Helen Petousis-Harris, vaccination specialist at the University of Auckland, based on SARS-CoV-2 transmission, a vaccine that is 89% effective at preventing infection is most likely effective at eliminating Covid-19 in populations where high vaccination coverage is achieved.

However, preliminary results tested in the laboratory only showed Covid-19 patients without symptoms. While it is not clear how the results of patients who had mild to severe symptoms when exposed to the SARS-CoV-2 virus.

Zoe McLaren, professor at the University of Maryland Baltimore County, said the study was also not designed to accurately measure the reduction in transmission of the coronavirus. According to him, the study compares the number of reported cases between those who have been fully vaccinated and those who have not been vaccinated.

“But vaccinated people tend not to be tested so the data will be less than the number of cases, especially asymptomatic cases, in this group,” he said.

In response to this, Pfizer and BioNTech said they were working on an analysis of real-world data from Israel, which would be shared as soon as it was completed. The spokesman declined to comment on unpublished data.

According to the data Worldometers, Israel has recorded 754,998 positive cases, with 5,596 deaths, and 709,621 managed to recover as of Tuesday (23/2/2021).
