Pfizer CEO Albert Bulla said on the 16th (local time) that he expects the world to return to normal life by the end of next year.
"I think the world will have enough vaccines to protect everyone by the end of 2022," Bulla said in an interview with CNBC. said.
It is expected that developed countries will be able to secure enough doses of COVID-19 vaccine by the end of the year and developing countries by next year.
Germany's Biontech and Pfizer achieved the cumulative production of 1 billion doses of COVID-19 vaccine last week.
CEO Bulla said that Pfizer has signed vaccine supply contracts with more than 120 countries around the world, and that most of the vaccine production so far has been delivered to developed countries.
This is because 'rich countries' have pre-ordered Pfizer vaccines in advance.
However, as most developed countries have completed immunizing their own citizens, CEO Bulla predicted that more vaccines will be delivered to developing countries from the second half of this year.
He also said that Pfizer is preparing to produce a booster shot for the COVID-19 vaccine.
In another interview earlier, CEO Bulla mentioned that it is highly likely that the booster shot will be needed within 12 months after the two doses of immunity are fully developed.
