Some Covid vaccines may be “better suited” for certain age groups or for use as boosters, a scientist working on the Novavax trial said today.

Professor Paul Heath, chief investigator of the Novavax trial, said the wide range of vaccines used to help fight the pandemic would help leaders “fine-tune the immunization schedule.”

He said over time some vaccines might prove to be “better suited” for certain age groups while others might be more suitable for booster doses.

The scientist made the comments when asked on Sky News why it was important to have a lot of different vaccines.

“So we can show, for example, that certain vaccines are more appropriate for certain groups of elderly people, for those with underlying health problems, and so on.

“I think over time we may define different groups for different vaccines.”

Professor Heath, who is also director of the Vaccine Institute at St George’s, University of London, added: ‘We are looking at, for example, vaccinating adolescents and children, we are looking at and actually vaccinating pregnant women and there may be studies show that some vaccines may be better suited to different groups.

“So having this range of vaccines using a range of different technologies will ultimately allow us to refine the vaccination program.

“We’ve already heard over the weekend a proposal that booster doses will be considered and possibly implemented later this year and different vaccines may be better suited to be booster doses.

“So again, having a whole range of different vaccines using different vaccine technologies allows us to refine the program that we have right now.”
