Pfizer Shot Offers Partial Omicron Shield in Study: Virus Update

Article content

(Bloomberg) — Omicron’s ability to evade vaccine and infection-induced immunity is “robust but not complete,” researchers in South Africa said. The data come from the first reported experiments gauging the effectiveness of Covid-19 inoculations against the strain.

Infections are surging in the Nigerian city of Lagos, Africa’s largest, as the rate of positive tests jumped to 6% from 0.1% in mid-November. Europe will see a rise in deaths and hospitalizations from Covid-19, a health agency warned, because vaccination rates remain insufficient to counter trends.

Pfizer Shot Provides Partial Omicron Shield (3:30 p.m. NY)

Omicron’s ability to evade vaccine and infection-induced immunity is “robust but not complete,” said the research head of a laboratory at the Africa Health Research Institute in South Africa.

In the first reported experiments gauging the effectiveness of Covid-19 vaccines against the worrisome new strain, researchers at the institute found that the variant could partially evade the vaccine produced by Pfizer Inc. and BioNTech SE. Still, its evasion wasn’t complete and a booster shot could provide additional protection, Alex Sigal said in an online presentation on Tuesday.

Early signs show it’s likely more transmissible, while anecdotal data show “we are not seeing a very severe profile of disease,” and it might be less severe. However, he warned those data could be because the early cases are among young people.

Biden Mandate for Federal Contractors Blocked (1 p.m. NY)

The Biden administration’s mandate for federal contractors’ employees to be vaccinated will be halted nationwide, amid a slew of challenges from states that say the president overstepped his authority in requiring the Covid-19 shots.

Scotland Braces for Rapid Surge (10:30 a.m. NY)

Scotland is likely to face a continued and “potentially rapid” rise in coronavirus cases in the coming days amid a surge in the omicron variant in large parts of the country, First Minister Nicola Sturgeon said.

The doubling time for cases may be as short as two to three days, while the so-called R number that gauges how quickly the virus is transmitted may be more than 2, she told lawmakers in Edinburgh on Tuesday. Anything over 1 suggests infections are running out of control.

Facing criticism from business groups that the announcement came as a surprise, De Blasio reiterated that the move is a “preemptive strike” to head off a potential upsurge in cases and that businesses wouldn’t want further restrictions.

De Blasio also emphasized his decision not to impose a vaccine mandate on school-going children, saying that schooling is essential.

European Union regulators endorsed mixing two different Covid-19 shots for initial vaccine schedules and boosters, saying hybrid approaches can increase governments’ flexibility in responding to the new omicron variant.

Combining viral vector vaccines like AstraZeneca Plc with mRNA jabs such as Pfizer Inc. generates a good level of antibodies against Covid-19 and a higher T-cell response, another part of a person’s immune defense, compared to giving doses of the same shot, according to data analysed by the European Medicines Agency and the European Center for Disease Prevention and Control. That’s true for first and second doses, as well as boosters, the agency said.
