A new research shows that relaxing restrictions like mask-wearing and social distancing when most people have been vaccinated greatly increases the risk of vaccine-resistant variants of COVID-19.

At a time when nearly 60 percent of Europeans have received at least one vaccine dose, the authors said their modelling study showed the need to maintain non-vaccination measures until everyone is fully jabbed.

Predictably, the model showed that a rapid rate of vaccination reduced the risk of a resistant strain emerging. "Vaccines are our best bet to beat this pandemic" said co-author Simon Rella, from Austria's Institute of Science and Technology . With SARS-CoV-2, the Delta variant is significantly more infectious than the original virus variant, but there is currently little evidence to suggest it is more deadly.Authors said that their research highlighted the need to maintain other anti-Covid measures until everyone is vaccinated.

Currently just over one billion people around the world are fully vaccinated against Covid-19, with many countries -- particularly in Africa and South America -- yet to start widespread rollouts due to lack of supply.
