“We need a combination of measures,” said Spector, who directs the ZOE Covid study at King’s College London. “How calm we want these rates to be last year is decided by our calmness and our relaxation with some rules that seemed overwhelmed to me last year, and now I think this year is not enough.”
However, the vaccine rate is the most important factor that explains the variation between countries like Croatia and Italy.
Many Eastern European countries have lower vaccination rates than some of their neighbors: Croatia is 46% fully vaccinated, for example, and Slovakia is 43%. (The European average is around 56%) Uncertified people are pushing for an increase in numbers, said Austrian Chancellor Alexander Schallenberg when announcing a new blockade on his country: ” [daily infection] The vaccination rate is over 1,700 and the vaccination rate is 383 ”.
When vaccination rates are higher, the results are more serious illness and death, even if the transmission is high. In the UK, 80% of people over the age of 12 have had two doses of the covid vaccine, for example.
“The best-performing countries are those with high vaccine coverage and effective measures,” says Salathé. “The worst countries are those that have neither. Most of them are involved. ”
But even if vaccination rates are high and the pressure on cases is relatively low, they may not be sufficient for long-term protection, especially considering that the effectiveness of vaccines disappears over time.
“The UK expanded its vaccination program earlier than most countries, so it has been aware of the impact of declining immunity earlier,” says Michael Head, a senior global health researcher at the University of Southampton. “Here UK developers are making an impact on new cases of hospital admissions and the elderly population.”
This means that it is essential to continue vaccinating people and to increase the immune response of people who were vaccinated at the beginning of the cycle.
“Where we see uncontrolled outbreaks, we also see new variants of interest and concern, and we don’t want new variants to become dominant and have a greater impact on the effectiveness of our vaccines,” he says. “Ultimately, the world can’t fully relax until the vast majority of the world is vaccinated. The combination of the question of vaccination and the lack of access to vaccines is everyone’s problem. “
