A new Covid-19 wave appears to be brewing in Europe as cooler weather arrives, with public health experts warning that vaccine fatigue and confusion over types of shots available will likely limit booster uptake.
Omicron subvariants BA.4/5 that dominated this summer are still behind the majority of infections, but newer Omicron subvariants are gaining ground. Hundreds of new forms of Omicron are being tracked by scientists, World Health Organization (WHO) officials said this week.
WHO data released late on Wednesday showed that cases in the European Union reached 1.5 million last week, up 8% from the prior week, despite a dramatic fall in testing. Globally, case numbers continue to decline. Hospitalization numbers across many countries in the 27-nation bloc, as well as Britain, have gone up in recent weeks.

In the week ending October 4, Covid-19 hospital admissions with symptoms jumped nearly 32% in Italy, while intensive care admissions rose about 21%, compared to the week before, according to data compiled by independent scientific foundation Gimbe.
Over the same week, Covid hospitalizations in Britain saw a 45% increase versus the week earlier.
Omicron-adapted vaccines have launched in Europe as of September, with two types of shots addressing the BA.1 as well as the BA.4/5 subvariants made available alongside existing first-generation vaccines. In Britain, only the BA.1-tailored shots have been given the green light.
European and British officials have endorsed the latest boosters only for a select groups of people, including the elderly and those with compromised immune systems. Complicating matters further is the “choice” of vaccine as a booster, which will likely add to confusion, public health experts said. But willingness to get yet another shot, which could be a fourth or fifth for some, is wearing thin.
“For those who may be less concerned about their risk, the messaging that it is all over coupled with the lack of any major publicity campaign is likely to reduce uptake,” said Martin McKee, professor of European public health at the London School of Hygiene and Tropical Medicine. “So on balance I fear that uptake will be quite a bit lower.” Meanwhile, British officials last week warned that renewed circulation of flu and a resurgence in Covid-19 could pile pressure on the already stretched National Health Service.
