Pfizer-BioNTech COVID-19 vaccine

Vaccine nationalism may strongly impact global trajectories of Covid-19 case numbers and increase the potential emergence of novel variants, warn researchers. A team of researchers from the US and Canada projected forward the incidence of Covid-19 cases under a range of vaccine dosing regimes, vaccination rates, and assumptions related to immune responses.

They did so in two model regions: One with high access to vaccines (HAR) and a low-access region (LAR). The models also allowed for the regions to be coupled either through case importation, or the evolution of a novel variant in one of the regions. The study is published in the journal Science.

"Certain countries such as Peru and South Africa that have had severe Covid-19 outbreaks have received few vaccines, while many doses have gone to countries experiencing comparatively milder pandemic impacts, either in terms of mortality or economic dislocation," said Caroline Wagner, Assistant professor of bioengineering at McGill University. Overall, the study found that increased vaccine-sharing resulted in reduced case numbers in LARs.

"Because it appears that vaccines are highly effective at reducing the clinical severity of infections, the public health implications of these reductions are very significant," said Michael Mina, Assistant Professor at the Harvard T.H. Chan School of Public Health.

On the other hand, the models predicted that sustained elevated case numbers in LARs with limited vaccine availability will result in a high potential for viral evolution, underlying the importance of rapid, equitable global vaccine distribution. As the pandemic progresses, viral evolution may play an increasingly large role in sustaining transmission, the researchers said.

Further, they noted that there are additional considerations for vaccine equity beyond epidemiological and evolutionary ones.

"Ethics also argues against countries stockpiling vaccines or allocating doses for boosters. This study strongly supports that ethical position showing that stockpiling will undermine global health," said Ezekiel Emanuel, Professor at the University of Pennsylvania.

High drama was witnessed in Kanpur Dehat for over an hour when a man, upset over his wife's alleged affair with a local man, climbed the tower with his children and threatened to commit suicide. The incident took place on Monday near Gandhi Nagar in Akbarpur, when the man threatened to commit suicide after throwing his kids down from a height of nearly 40-feet. Chaos prevailed around the area and the locals informed the police that rushed to the spot.

After about half-an-hour of convincing, the police managed to bring him and his children down. The man told the police that his wife's affair was going on with his neighbor. He had complained to the police, but no action was taken. Police said that as per the man, his wife had developed an illicit relationship with a man, living nearby their house. "As per the man, in his absence, his neighbor visited his house often. He said that he had reprimanded his neighbor many times, but to no avail," said the police.

The US forces continued their bombardment of buildings and institutions in Syria's northeastern Hasakah province, as part of their alleged manhunt of Islamic State (IS) fugitives, state news agency SANA reported. The US forces are shelling buildings and public institutions on Tuesday in the vicinity of the Sina'a prison in the Gweiran neighborhood in Hasakah "on the pretext of hunting down IS militants who fled the prison," said SANA.

The circulating avian influenza outbreaks, including in India, do not seem to pose the 'high' risk but surveillance and biosecurity measures are necessary to reduce spillover risk between poultry and wild birds, a UN-backed scientific task force said. Throughout the past autumn and current winter in the northern hemisphere, multiple avian influenza outbreaks, caused predominantly by the H5N1 HPAI virus, plus other subtypes, including H5N8, have occurred in India, the UK, the Netherlands and Israel with the ever recorded mortality of the Svalbard barnacle geese in Solway Coast.
