(CNN/CNN Newsource) - Pfizer's CEO says he hopes the COVID-19 vaccine becomes a yearly shot, instead of having boosters every few months. Albert Bourla said this in an interview with an Israeli news outlet. He said he wants people to get an annual COVID-19 vaccine like the flu. Bourla said it would be easier to convince people to get vaccinated that way. Right now Pfizer is looking to create a vaccine that protects against omicron and some of the other variants.
