  • CNBC reports Pfizer CEO Albert Bourla made the comments during an event recorded April 1, which were made public on Thursday.
  • “It is extremely important to suppress the pool of people that can be susceptible to the virus,” Bourla told CNBC’s Bertha Coombs during an event with CVS Health.
  • Meanwhile, Moderna CEO Stephane Bancel said the company could provide a booster shot by fall.

A booster dose of the Pfizer-BioNTech vaccine will likely be needed for patients within 12 months of becoming fully vaccinated as variants challenge the effectiveness of the shots, according to Pfizer CEO Albert Bourla.

Bourla also said people may need to be vaccinated against COVID-19 annually, similar to that of the seasonal flu shot. 

“It is extremely important to suppress the pool of people that can be susceptible to the virus,” Bourla told CNBC’s Bertha Coombs during an event with CVS Health. 

It’s still not settled exactly how long protection against COVID-19 lasts once someone has been inoculated; however, Pfizer earlier this month announced its vaccine has shown to be more than 91 percent effective against the disease for at least six months following the second dose. 

Bourla’s estimate falls in line with Anthony Fauci’s comments earlier this week when he said there’s a possibility those who have been fully vaccinated may require a booster in as little as a year. 

“If it turns out a year or a year and a half, we very well may need to get booster shots to keep up the level of protection,” Fauci told MSNBC’s Mehdi Hasan. 

Meanwhile, Moderna CEO Stephane Bancel said Wednesday the Massachusetts-based biotech firm could submit data on its booster shot to federal regulators in the coming months and provide the shot to Americans by the fall.
