Speaking to The Malta Independent, virologist Chris Barbara stated that the vaccines available in Malta, notably Pfizer and AstraZeneca, are effective agains the COVID-19 variants. Following the registering of the first Indian variant (Delta) case in Malta last Friday, the virologist assured the public that vaccines are effective against the variants and that this is backed by various studies.
Barbara quoted a UK study which shows that Pfizer vaccines build up 88% immunity against the Delta variant when a person is fully inoculated. Full AstraZeneca vaccinations provide 60% effectiveness. Barbara also emphasised that the Indian, UK, Brazil and South African variants are variants of concern, which, so far, the vaccine is effective against. For a variant to render the vaccine ineffective, the variant would have to be classified as ‘high consequence’. There has yet to be such a case with COVID-19 globally.
