Pfizer wants to develop its own mRNA vaccines

After the success of the Covid vaccine developed jointly with Biontech, US pharma giant Pfizer wants to further expand its vaccine business - possibly even without its German partner. "We're happy to work with Biontech, but we don't have to work with Biontech," Pfizer CEO Albert Bourla told the Wall Street Journal.

The novel mRNA technology has "dramatic potential" and Pfizer is confident it can now develop mRNA vaccines on its own, Bourla said, according to the editorial version distributed on the newspaper's website. "We have developed our own expertise." The two companies would continue to cooperate on Covid-19 vaccines.
