The Pfizer COVID-19 vaccine is effective after up to 6 months and has been studied.

Pfizer and its German partner BioNTech announced on Thursday the latest results of an ongoing late-stage study of more than 44,000 volunteers.

According to both companies, the vaccine was 91% effective against symptomatological disorders and was even more effective in preventing severe illnesses. Of the 927 confirmed COVID-19 cases detected by March 13, 77 were vaccinated and 850 were dummy shots.

There were no serious safety concerns, and the vaccine appeared to be effective against the first mutants detected in South Africa, the two companies said.

The United Kingdom and the United States issued an urgent green light to deploy Pfizer’s vaccine at the end of last year, followed by many other countries. The vaccine is licensed for people over 16 years of age.

This week, the two companies said the vaccine is safe and strongly protected even in a 12-year-old child, based on a study of 2,260 US volunteers.

The Pfizer COVID-19 vaccine is effective after up to 6 months and has been studied.
