According to a report in The Lancet, a third vaccine dose is not necessary as vaccines already provide enough protection against Covid-19.
This comes as certain countries have been administering third vaccine doses to the more vulnerable people of their populations, such as the elderly and those with underlying health conditions.
The World Health Organisation (WHO) has always expressed opposition towards the idea of a third vaccine, stating that vaccine supplies should be delivered to poorer nations.
However, reports from scientists, including the WHO, concluded that booster doses are not appropriate at this stage of the pandemic, even with the threat of the highly transmissible Delta variant.
The authors of the study found that vaccines remain highly effective against all of the main virus strains.
Lead author Ana-Maria Henao-Restrepo of the WHO stated, “Taken as a whole, the currently available studies do not provide credible evidence of substantially declining protection against severe disease, which is the primary goal of vaccination,”.
She stated that vaccines should be administered to people who are still awaiting a jab and that they should be delivered to areas where they will do the most good.
In the scenario where new virus mutations emerge, the authors stated that specially modified vaccine boosters should be developed against these mutations and not the current vaccines that are available right now.
WHO chief Tedros Adhanom Ghebreyesus called for all countries to avoid giving extra vaccine jabs until the end of the year.
