Repeated boosters not viable strategy against new variants, WHO warns
World Health Organization experts have warned that repeating booster doses of the original Covid vaccines is not a viable strategy against emerging variants.
the WHO Technical Advisory Group on Covid-19 Vaccine Composition (TAG-Co-VAC) said:
A vaccination strategy based on repeated booster doses of the original vaccine composition is unlikely to be appropriate or sustainable.
Covid-19 vaccines that have high impact on prevention of infection and transmission, in addition to the prevention of severe disease and death, are needed and should be developed.”
The group said there could be a need to update the existing vaccines to better target emerging Covid variants such as Omicron and called for the development of new jabs that not only protect people who contract Covid against falling seriously ill but also better prevent people from catching the virus in the first place.
It also suggested that vaccine developers should strive to create jabs that “elicit immune responses that are broad, strong, and long-lasting in order to reduce the need for successive booster doses”.
Until new vaccines have been developed, the group said, “the composition of current Covid-19 vaccines may need to be updated”.
According to the WHO, 331 candidate vaccines are currently being worked on around the world.

Over in Quebec, Canada’s second-most populous province, has announced plans to impose a ‘health tax’ on residents who refuse to get the Covid-19 vaccination for non-medical reasons.
Premier François Legault announced the new “contribution” for the unvaccinated on Tuesday, adding that it will apply “in the next few weeks”.
“A health contribution will be charged to all adults that don’t want to get vaccinated,” he said. “Those who refuse to get the shot bring a financial burden to hospital staff and Quebecers. The 10% of the population can’t burden the 90%.”
