Hello everyone?
‘BNT162b2’ is a candidate vaccine for the prevention of COVID-19 developed by Pfizer, an American pharmaceutical company, and Bioen Tech, Germany.
Pfizer published an interim phase 3 clinical trial showing that this b2 had a prophylactic effect of more than 90%.
Since the flu vaccine is approximately 50% effective and is equivalent to the measles vaccine, which is the highest at 93%, expectations around the world are rising.
“I finally see the light at the end of the tunnel,” said Pfizer.
First of all, reporter Kim Jung-won reports whether it will become a new dream drug to conquer Corona 19.

In July, Pfizer divided the 39,000 clinical trial participants into two groups, each half.
On the one hand, the developing COVID-19 vaccine was administered to the other and a placebo or sham vaccine was administered to the other.
[앨버트 불라/화이자 CEO(지난 9월)]“If the vaccine works, those who contract COVID-19 will come from the unvaccinated group.”
Of these, 94 people were infected with corona.
They were both vaccinated twice and tested positive after at least a week.
Pfizer said that more than 90% of 94 people had a preventive effect, but less than 10% of those who received the vaccine in development and were infected with coronavirus were interpreted as less than 10%.
Pfizer said no serious side effects have been found so far and it will apply for emergency use approval from the FDA within the next week.
[앨버트 불라/화이자 CEO]“It is a great day for science and a great day for humanity. The hope of billions of people (to fight the crown) was felt on our shoulders.”
Given that the overall protection rate of the flu vaccine is 40-60%, it is a common assessment that Pfizer’s performance is remarkable.
[앤서니 파우치/美 국립 알레르기·전염병 연구소장]“It’s surprising that it’s more than 90% effective. It’s going to play an important role in the research.”
However, it is still questionable how long immunity will last just one week after vaccination.
Additionally, detailed data such as the age and race of 94 people with coronavirus and how many people had received the vaccine in development were not disclosed.
Above all, it remains to be seen whether the Pfizer vaccine will prevent severe cases or asymptomatic infections.
