Albert Bourla, CEO of Pfizer Inc., said it is likely that people who receive Covid-19 vaccines will need a shot shot to maintain the virus against the virus within a year after that, and then annual vaccinations. .
‘The variants will play a key role. “It is extremely important to suppress the group of people who may be susceptible to the virus,” he said. Bourla said during a virtual event hosted by CVS Health Corp., which aired Thursday but was recorded on April 1st.
“There are vaccines like polio where one dose is enough,” Bourla said. ‘And there are vaccinations like flu that you need every year. The Covid virus looks more like the flu virus than the polio virus. ”
More research is needed to confirm the need for annual shots, he said. But he added that the need seems likely so far.
The CEO’s remarks come because the US and other countries want to vaccinate as many people as possible and try to stay ahead of the variants that could elude the shots.
