The World Health Organisation (WHO) has expressed doubts over the vaccine’s potential to end the pandemic.
This comes as new variants cast shadows on the hopes of reaching herd immunity.
Amid the possibility of the virus extending its stay for many years, questions are beginning to mount up in terms of how the vaccination strategy can be adapted.
Regional Director for Europe at WHO Hans Kluge stated that health officials must now anticipate how the vaccination strategy can be adapted, particularly in relation to additional vaccine doses.
Originally stating that the pandemic would be over as soon as we reached 70% minimum coverage in vaccinations, Kluge was asked if the figure was still a target or if more people would be needed to get vaccinated.
Upon answering the question, Kludge stated that the situation has changed as a result of new and more transmissible variants of the virus.
“If we consider that Covid will continue to mutate and remain with us, the way influenza is, then we should anticipate how to gradually adapt our vaccination strategy to endemic transmission and gather really precious knowledge about the impact of additional jabs,”.
Although crucial to containing the virus, epidemiologists have suggested that the idea of herd immunity being achieved solely through vaccinations is unrealistic.
The more contagious the virus, the higher the number for reaching herd immunity will be until the virus stops circulating.
