Pfizer planning to submit data on 4th Covid shot soon, while working on vaccine for all variants

Albert Bourla, CEO of Pfizer, told CNBC on Friday that the company is working on a vaccine that protects against all coronaviruses.

I think we will submit to FDA a lot of data about the need for a fourth dose, and they need to make their own conclusions, of course, and then CDC also.

We are making a vaccine that covers all of the different variations. He said that a lot of the trials will start reading by the end of the month.

The global economy ground to a halt after Covid was declared a Pandemic by the World Health Organization on March 11, 2020.

• Pandemic-fighting measures put into place shortly after, including mask mandates and travel restrictions, and then a major breakthrough came when Covid vaccines were developed and cleared for use.
• Since then, around 81.4% of the American population five years old or older have received at least one dose of vaccine out of the three cleared in the U.S. from Pfizer, Moderna and Johnson & Johnson, according to the Centers for Disease Control and Prevention. 
• Currently, daily Covid cases and deaths have dropped sharply since peaking in January this year due to the omicron wave. Several states have lifted mask mandates in schools and other public places.
• Companies including Google and Apple have called workers back into the office. Businesses, including restaurants, entertainment venues and more have also roared back to life.

Bourla remained vigilant in creating effective vaccines despite some semblance of normal returning.

He said that Pfizer is working on a vaccine that can prevent infections, as well as preventing hospitalizations and severe cases of the virus.

Bourla said that they can't have vaccines every six months.
