Pfizer

In a statement they published on their website, the company "Pfizer" stated that they did not conduct research on Gain-of-function research (GoF research or GoFR) - a medical research that genetically alters an organism in a way that may enhance the biological function and the potential of viruses.

Pfizer yesterday applied to the US Medicines Agency to allow the emergency use of the vaccine produced by the company to children aged 6 months to 4 years, AFP and Reuters reported.

Biontech says it expects to have more data within two weeks to help determine whether the coronavirus vaccine, which it co-developed with Pfizer, needs to be reworked because of a new version of the coronavirus discovered in South Africa.

Pfizer and Biontech have said they expect to be able to deliver a possible new vaccine made for the new version in about 100 days, if necessary.

Pfizer and BioNTech announced on July 8 they would seek authorization for a third dose of their COVID-19 vaccine to boost its efficacy, as the Delta variant drove devastating outbreaks in Asia and Africa and cases rose again in Europe and the United States.

US FDA expanded the emergency use authorization for Pfizer's Covid-19 vaccine including people ages 12 to 15.

Pfizer-BioNTech asked for authorization on April 9 to use their Covid-19 vaccine on 12 to 15-year-olds in the United States, which could mark a crucial next step toward achieving herd immunity.

The mass vaccination of teenagers would also relieve an enormous strain on parents who are juggling the demands of homeschooling their children while keeping up with jobs.

BioNTech-Pfizer said Wednesday their vaccine showed 100 percent efficacy against the coronavirus in 12 to 15 year olds, as they eye approval for adolescents to get the jabs before the next school year.

Phase 3 trials carried out on 2,260 adolescents in the United States "demonstrated 100 percent efficacy and robust antibody responses", the companies said in a statement.

Several EU countries are receiving significantly fewer doses of the Pfizer coronavirus vaccine than expected, after the US firm slowed shipments.

Six nations called the situation "unacceptable" and warned it "decreases the credibility of the vaccination process".

Sweden, Denmark, Finland, Lithuania, Latvia and Estonia urged the EU to apply pressure on Pfizer-BioNTech.

The United States notched a record number of coronavirus cases in 24 hours for the third day running, as it was reported that Britain's Queen Elizabeth II will get a vaccine within weeks.
