- herd immunity ‘not a possibility with Delta variant experts say
- warns that “anyone still unvaccinated at some point will meet the virus”.
The vaccines expert tells MPs they should not focus on herd immunity because a coronavirus variant could emerge that is even better at passing among vaccinated populations says an article on Sky News.
To not focus on ‘herd immunity
Herd immunity is “not a possibility” because the Delta variant is still spreading fast and infecting fully vaccinated people, the head of the Oxford Vaccine Group has said. Professor Sir Andrew Pollard told MPs that although 95% vaccination would stop the transmission of measles, the same was not true for COVID.
Highly transmissible variant
Herd immunity is when enough people become resistant to a disease – through vaccination or previous exposure – that it can no longer significantly spread among the rest of the population. The vaccine might slow the spread of coronavirus, but as the Delta variant – first identified in India – is highly transmissible, jabs will not contain it altogether.
