Pfizer, BioNTech and Moderna have generated more than $60 billion in sales this year and next from their Covid-19 vaccines. But now these firms can make billions of dollars more.
Analysts say the booster vaccine market could be as big as the $6 billion in annual flu vaccine sales, and last for years to come.
Vaccine makers say people who are fully immunized will need an extra dose to maintain protection against new strains. They say that after 6 months, the levels of antibodies will gradually decrease in those who are vaccinated.
This present. More and more countries are deciding to give booster shots to older people and people with weakened immune systems.
According to the president of Moderna, at some point, Covid-19 vaccines will become “a more traditional market”.
Meanwhile, Pfizer declined to comment. However, two weeks ago, executives told investors that a third booster dose would be needed 6-8 months after vaccination and should be given regularly thereafter.
