Pfizer claims effectiveness in mutations at UK , South Africa
Amid the new variant species of ongoing COVID-19 pandemic , The vaccine made by Pfizer and BioNTech appears to retain its effectiveness against coronavirus mutations in worrying new variants that have emerged recently in Britain and South Africa, the firms said Thursday, reports AFP.
Several new variants — each with a cluster of genetic mutations — have sparked fears over an increase in infectiousness as well as suggestions that the virus could begin to elude immune response, whether from prior infection or a vaccine.
Pfizer/BioNTech, which had previously said it was unlikely that the strain originally found in Britain could escape vaccine protection, said Thursday that early tests suggest their immunization would be similarly protective against the variant in South Africa.
In a statement, the two companies said these preliminary findings “do not indicate the need for a new vaccine to address the emerging variants.”
They said they are “prepared to respond” if a new strain is shown to be able to evade the immunity of the vaccine, adding that they can produce updates to their jab if needed.
