Ja, precis. Med evolutionärt tryck menar jag att miljön runt omkring skapar ett uppdämt behov för den mutationen.
Angående AstraZeneca, det är i linje med vad WHO påstår:

A small trial with 2,000 people in South Africa found that the AstraZeneca vaccine provided "minimal protection" against mild and moderate COVID-19 disease from the B.1.351 coronavirus variant, first identified in South Africa. This variant is causing the majority of infections within the country.
None of the people in the trial died, became severely ill or had to be hospitalized. Efficacy against severe COVID-19 arising from the B.1.351 variant was not assessed in the study because the participants were at lower risk, researchers at the University of the Witwatersrand in Johannesburg said in their analysis. The study has not yet been peer-reviewed.
The World Health Organization has recommended the use of the AstraZeneca vaccine even if variants are present in a country, according to interim recommendations published on February 10.
"Countries should conduct a benefit-risk assessment according to the local epidemiological situation including the extent of circulating virus variants," the interim recommendations state.
The WHO's recommendations state that indirect evidence is compatible with protection against severe COVID-19, and ongoing clinical trials and evaluations would be needed to demonstrate this.
Ja, ingen som vaccinerades med Astras vaccinet blev allvarligt sjuk och avled. Men det inträffade inte heller några dödsfall i kontrollgruppen, så slutsatserna därifrån blir minst sagt vanskliga.
Det vi vet är att Sydafrika avslutade vaccineringen och sålde vaccinet vidare.
