GENEVA, Dec 8, 2021 (BSS/AFP) - The Omicron variant appears to be no worse
than other coronavirus strains, top scientists from the WHO and the United
States told AFP, while cautioning that more research is needed to judge its
severity.

  The hopeful assessments came as global concern grew over the heavily
mutated variant, which has forced dozens of nations to re-impose border
restrictions and raised the possibility of a return of economically punishing
lockdowns.

  While it is likely more transmissible than previous variants, Omicron is
also "highly unlikely" to completely evade vaccine protections, the World
Health Organization's second-in-command told AFP on Tuesday.

  "The preliminary data doesn't indicate that this is more severe. In fact,
if anything, the direction is towards less severity," WHO emergencies
director Michael Ryan said in an interview, insisting though that more
research was needed.

  Ryan also said there was no sign that Omicron could fully sidestep
protections provided by existing Covid vaccines.

  "We have highly effective vaccines that have proved effective against all
the variants so far, in terms of severe disease and hospitalisation...
There's no reason to expect that it wouldn't be so" for Omicron, he added,
pointing to initial data from South Africa, where the strain was first
reported.

  However, Ryan acknowledged that it was possible that existing vaccines
might prove less effective against Omicron, which counts more than 30
mutations on the spike protein that dots the surface of the coronavirus and
allows it to invade cells.

  Top US scientist Anthony Fauci echoed the WHO's view, saying Omicron did
not appear worse than prior strains based on early indications -- and was
possibly milder.

  The new variant is "clearly highly transmissible," very likely more so than
Delta, the current dominant global strain, Fauci told AFP.

  "It almost certainly is not more severe than Delta," he added. "There is
some suggestion that it might even be less severe."

  But he noted it was important to not over-interpret this data because the
populations being followed skewed young and were less likely to become
hospitalised. Severe disease can also take weeks to develop.

  "Then as we get more infections throughout the rest of the world, it might
take longer to see what's the level of severity."

  - Global concern -

  The detection of the first Omicron cases last month coincided with surges
in infection numbers across the world, and the variant added fuel to concerns
about a global Covid resurgence.

  As European Union health ministers met Tuesday to find ways to coordinate
their response, Norway announced it will tighten restrictions to combat its
surge.

  It followed a suspected outbreak of Omicron last week among dozens of
partygoers who had all been vaccinated led to new restrictions in and around
the capital Oslo.

  Neighbouring Sweden also said Tuesday it would launch a series of anti-
Covid measures.

  Elsewhere in Europe, Poland said from December 15, it will restrict the
number of people allowed in churches, restaurants and theatres, and make
vaccination compulsory for healthcare workers, teachers and the military from
March 1.

  - Growing frustration -

  While the positive initial assessments of Omicron helped lift the mood,
especially among global markets as fears of another economic downturn
subsided, the variant's emergence has highlighted that the fight against the
pandemic is far from over.

  Covid-19 has killed more than 5.2 million people around the world since the
coronavirus was first declared in late 2019, with scientists and health
experts saying vaccinations and continued social distancing are keys to
defeating the disease.

  But vaccine requirements have led to resistance in many countries, either
because of misinformation and conspiracy theories or the economic and
logistical impact of such mandates.

  Around 4,000 people protested in Brussels on Tuesday against a plan by the
Belgian government to make vaccines compulsory for health workers from early
next year.

  "We are in favour of vaccination, but why only health workers?" said nurse
Perrine.

  "Because everyone must be vaccinated, it is everyone or no one."
