Brazil coronavirus variant spreads more easily, dodges immune defenses: Scientists

  • Prof. Christophe Fraser: ‘In Manaus, that population had had an incredibly high infection rate in the first wave, and yet was re-infected’
  • Prof. Christophe Fraser: ‘We have quite a lot of data that suggests we should be a little bit concerned over the possibility that it could spread’

LONDON: The Brazilian variant of coronavirus can spread rapidly and bypass immune system defenses, according to a new study.

A team of scientists from Brazil and the UK said the so-called P1 variant is about 1.4 to 2.2 times more transmissible than older versions of coronavirus that exist in the Brazilian city of Manaus, where the new variant originated.

P1 can also dodge 25-61 percent of the immunity built up from previous infection, said researchers from Imperial College London and the University of Sao Paulo. The results of the study are awaiting peer review.

Meanwhile, Prof. Christophe Fraser of the University of Oxford warned that P1 “can re-infect people who have been infected naturally.”

He told Sky News: “In Manaus, that population had had an incredibly high infection rate in the first wave, and yet was re-infected.”

He said: “What we don’t know is the degree of protection the vaccines provide against this strain. We have quite a lot of data that suggests we should be a little bit concerned over the possibility that it could spread.”

He added: “It may be we have to update the vaccines, but we really don’t want to be updating the vaccines before the summer.”

Afghan Taliban says Pakistan bombs Kabul in fresh escalation

KABUL: The Afghan government said on Friday that Pakistan had carried out fresh strikes on Kabul and several other provinces.

Taliban government spokesman Zabihullah Mujahid said in a post on X that Kabul, Kandahar, Paktia, Paktika, and some other areas, were targeted.

Pakistan has killed at least 641 Afghan Taliban operatives and injured more than 855 in the ongoing conflict between the two sides since last month, Information Minister Attaullah Tarar said on Wednesday.

Islamabad has said its airstrikes, which have at times directly targeted the Afghan Taliban government, are aimed at ending Kabul’s support for militants carrying out attacks on Pakistan. The Taliban has denied aiding militant groups.

Fresh clashes between the two neighbors began on Feb. 26 after Afghanistan’s border forces launched attacks against Pakistani military installations. Kabul said the attack was in retaliation for Islamabad’s airstrikes earlier in February. Both forces have since then engaged in the worst fighting between them in decades.

Relations between Pakistan and Afghanistan have remained strained since the Afghan Taliban seized power in August 2021. Pakistan has witnessed a surge in militant attacks across the country in recent months that it blames on militants it alleges are based in Afghanistan. Kabul denies the allegations and insists that its soil is not used by militant groups for attacks against other countries.

While Afghanistan has voiced the desire for dialogue, Pakistan has repeatedly ruled out talks, saying it will continue targeting militant hideouts through “Operation Ghazab lil Haq” until Kabul desists from supporting militants.
