Kundi la Wanasayansi wa Kimataifa limesema Chanjo za nyongeza (Booster shots) dhidi ya Virusi vya Corona hazihitajiki kwa Umma katika hatua hii ya mlipuko na ushahidi zaidi unahitajika kuzihalalisha
Wameeleza hayo katika Ripoti iliyochapishwa na Jarida la The Lancet ambapo pia wamesisitiza chanjo bado zina ufanisi mkubwa dhidi ya dalili kali za aina zote kuu za Virusi vya Corona ikiwemo Delta
Hata hivyo, Ripoti hiyo imekiri kuwa watu wengine wakiwemo wale ambao kinga yao ya mwili imedhoofu wanaweza kufaidika na chanjo ya nyongeza

Additional COVID-19 vaccine booster shots are not needed for the general population, a group of international scientists has said in a new report in a medical journal.
The report, published in The Lancet on Monday, concluded that even with the threat of the more contagious Delta variant, “booster doses for the general population are not appropriate at this stage in the pandemic.”
“Any decisions about the need for boosting or timing of boosting should be based on careful analyses of adequately controlled clinical or epidemiological data, or both, indicating a persistent and meaningful reduction in severe disease,” the scientists wrote.
The scientists said more evidence was needed to justify boosters, and that vaccines remain highly effective against severe symptoms of COVID-19, across all the main virus variants including Delta.
“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,” said lead author Ana-Maria Henao-Restrepo, of the WHO.
She said vaccine doses should be prioritised to people around the world still waiting for a jab.
“If vaccines are deployed where they would do the most good, they could hasten the end of the pandemic by inhibiting further evolution of variants,” she added.
That view runs counter to US government plans to begin offering another round of shots to many fully vaccinated Americans as soon as next week, contingent on approval from health regulators.
The authors acknowledged that some individuals, such as those who are immunocompromised, could benefit from an additional dose.
A panel of experts that advises the US Food and Drug Administration on vaccines plans to meet on September 17 to discuss additional doses of the Pfizer-BioNTech shot, the first step in a wider booster rollout.
The Lancet article’s authors included WHO top scientists Soumya Swaminathan, Ana-Maria Henao-Restrepo and Mike Ryan.
