Experimental vaccine shows potential against Zika virus. (IANS)

An experimental single dose vaccine against the Zika virus has proven to be powerful in mice, new research has found.

The vaccine employs an uncommon two-pronged approach to fighting the virus, which is spread by mosquitoes and is most serious for pregnant women and their foetuses.


The vaccine, carrying genes for two or three Zika proteins, proved effective in triggering an immune response that prevented later infection by the virus.

“The vaccine was potent, safe and highly effective, at least in the short term. There’s a long way to go, but we think this is a promising candidate for a human vaccine,” said lead author Jianrong Li, professor at The Ohio State University in the US.

The experimental vaccine holds particular promise because it appears to afford an adequate immune response with one dose. In hard-to-reach and resource-poor areas, that becomes especially valuable, added Shan-Lu Liu, co-author at the varsity.

In the study, appearing in the journal Nature Communications, the team targeted a protective immune response by expressing two or three Zika proteins and looked to vesicular stomatitis virus, or VSV — a foot-and-mouth disease in cattle.

In the experimental vaccine, VSV acts as a vehicle to deliver the genes for two or three key proteins from the Zika virus, carrying them into the mouse and expressing them inside some of the cells in the mouse so that the immune system could respond and build up a defence against Zika.

In addition, experiments in mice with severely compromised immune systems showed that vaccination helped their weak immune systems to fight off the virus swiftly and efficiently.

The early success with this vaccine has encouraged this team to use the same approach to fight other related viruses, including Dengue fever, the researchers said.

However, the next big question is “will this be protective in humans?”, the researchers said. (IANS)

The UK government on Thursday announced that it will move India from the red to the amber list on Sunday, in the country's latest update to the 'Red-Amber-Green' traffic light ratings for arrivals into England amid the Covid-19 pandemic.

This means the visit visas for the UK from India are open, in addition to other long-term visas that have remained open. But travellers from India arriving in England can complete a 10-day quarantine at home or in the place they are staying (not mandatorily quarantine in a managed hotel).

Pakistan has failed miserably to protect Hindus, their interests.

A Hindu temple in Pakistan's Punjab province was reportedly vandalized by hundreds of people after a nine-year-old Hindu boy, who allegedly urinated at a local seminary, received bail, a media report said on Thursday.

According to the Dawn news report, the incident took place on Wednesday in Bhong town, about 60 km from Rahim Yar Khan city.

Besides the vandalization, the mob also blocked the Sukkur-Multan Motorway (M-5), the report added.

Citing sources, Dawn news said that a case was registered against the minor on July 24 based on a complaint filed by a cleric, Hafiz Muhammad Ibrahim, of the Darul Uloom Arabia Taleemul Quran.

The sources said that "some Hindu elders did tender an apology to the seminary administration saying the accused was a minor and mentally challenged".

But, when a lower court granted him bail a few days ago, some people incited the public in the town on Wednesday and got all shops there closed in protest, the report quoted the sources as further saying.

A video clip showing people wielding clubs and rods storming the temple and smashing its glass doors, windows, lights, and damaging the ceiling fans went viral on social media.
