The US, the UK and other major economies could be on the brink of over-vaccinating people in the fight against Covid, experts say.
Israeli officials have already announced their intentions to embark on dishing out another round of booster jabs, meaning both the US and UK will eventually face pressure to follow suit even though both nations have insisted there are no plans to administer fourth doses yet.
But scientists argue that rolling out vaccines every three-to-four months simply isn’t ‘doable’ and may not even be necessary because of Omicron, which some believe will speed up the process of endemicity and consign days of sky-high hospitalization and death figures to history.
And they called for more data on dosing gaps between boosters before pressing ahead with plans to administer fourth jabs. Some experts claim the benefits of extra jabs are minimal because their primary purpose – preventing deaths and hospitalizations – has barely waned after a year and several Covid variants, effectively meaning boosters are adding to an already high base level immunity.
Professor Ian Jones, a virologist at the University of Reading, said descriptions of Omicron being a ‘natural vaccine’ were right.
The logic behind the argument is that as Omicron is highly transmissible but milder than other variants, it can give an immunity boost without causing as much serious illness, with some data suggesting a combination of infection than vaccination providing the best type of immunity in the long-run.
