Two doses of Covid-19 vaccine provide 87% efficacy

Two doses of Covid-19 vaccine provide 87% efficacy Disclosure

The study was carried out by a team including researchers from Nagasaki University.

Taking two doses of vaccine, both from Pfizer and Moderna, is 86,8% effective against developing Covid-19, announced on Tuesday (5) a team including researchers from the University of Nagasaki.

The team's vaccine efficacy data is about 10 percentage points below the numbers presented by the National Institute of Infectious Diseases (NIID).

The researchers, however, conducted the study about a month later, at a point when they believed the alpha variant of the virus had been replaced by the highly transmissible delta.

The team conducted the study in July and August at 10 medical institutions in 9 provinces and examined 890 individuals between 16 and 64 years of age suspected of having been infected with the coronavirus.

Of the 528 people who had not been vaccinated, 213 tested positive. Of the 108 who had received the first dose, 31 tested positive, while only 9 of 159 individuals who had been inoculated twice had been infected with Covid-19.

Results from a study conducted by the NIID from June to July showed that receiving two doses of vaccine was 95% effective.

However, Haruka Maeda, a researcher especially aimed at respiratory infection at Nagasaki University, said the vaccine's effectiveness may have weakened because the delta variant increased in June.

Maeda also emphasized that "despite this, it has been confirmed that the effectiveness of vaccines is still high in Japan as well."
