H7N9 virus: Should SA be worried?

30 April, 2013

See on Scoop.itVirology News

It has been described as one of the world’s most lethal flu viruses.

More than 20 people have already died from it in China, and more than 100 are infected.

The new strain of bird flu, the H7N9, has caused such a stir in the medical field that local practitioners are on a drive to educate South Africans on the importance of getting flu vaccines.

“This strain is actually nothing new, but the virus is changing itself… it’s becoming bigger and it is absolutely critical that everyone be vaccinated. It doesn’t appear that any South Africans have contracted or are in danger of the virus. but flu spreads quickly, and while we don’t want to scare people, there needs to be awareness,” said Professor Lynne Webber, head of the medical virology department at the University of Pretoria.

Ed Rybicki‘s insight:

Seconded on people getting flu vaccines…although there IS no available vaccine that would protect against this one, so the point is moot!

 

What this points up rather strongly is that SA needs a capacity to make emergency response vaccines – because we most definitely will not get any from anyone else, if this one goes pandemic, just as happened in 2009 with the H1N1pdm virus.

WHO: New flu passes more easily from bird to human

29 April, 2013

See on Scoop.itVirology News

A new strain of bird flu that emerged in China over the past month is one of the “most lethal” flu viruses so far, worrying health officials because it can jump more easily from birds to humans than the one that started killing people a decade ago,…

Ed Rybicki‘s insight:

Frightening…!  Which is the adult way of saying "scary".

Characterizing the killer H7N9

29 April, 2013

See on Scoop.itVirology News

What scientists are learning about the zoonotic flu virus that has infected more than 100 people in China since February.

The virus appears to be more virulent than past H7 avian flu viruses in past outbreaks, which have caused conjunctivitis but have only been blamed for one death. Furthermore, this virus appears to be spreading from its hosts to humans unusually readily

Ed Rybicki‘s insight:

March 31 to April to publish several papers on the virus: new technology has enabled SUCH rapid progress these days, it is almost unbelievable.

Ineffective – HIV Vaccine Trial Discontinued

27 April, 2013

See on Scoop.itVirology News

The National Institute of Allergy and Infectious Diseases (NIAID) has announced that it will halt its HVTN 505 HIV vaccine

trial due to a perceived lack of efficacy. A scheduled review by an independent data and safety monitoring board found that the vaccine regimen neither prevented HIV infection nor reduced viral load in vaccine recipients who became infected with HIV.

The announcement will come as a blow to those hoping the HVTN 505 would be an effective intervention to stem the HIV pandemic.

Ed Rybicki‘s insight:

And another one bites the dust…not only not effective, suspected of increasing infection rates.  VERY sad!

Hepatitis A virus discovered to cloak itself in membranes hijacked from infected cells

12 April, 2013

See on Scoop.itVirology News

Viruses have historically been classified into one of two types – those with an outer lipid-containing envelope and those without an envelope.

Ed Rybicki‘s insight:

…and hep A steals membranes from liver cells to circulate as an enveloped particle(s) in blood. This is a fascinating find, and doubtless will be followed by similar for other viruses.

 

The commentary has some speculation as to how vacciens work, if antibodies can’t see the virus – but they forget the virus has to get INTO the host in the first place, and environmental forms are non-enveloped, AND that the vaccine may well elicit some degree of cell-mediated immunity, which would target infected cells displaying degraded protein on tehir surfaces via MHC I-type receptors.

Mississauga Article: Making vaccine for new bird flu virus could be a challenge

12 April, 2013

See on Scoop.itVirology News

TORONTO — Making a vaccine to protect against the new bird flu virus that has emerged in eastern China could prove to be problematic, influenza experts acknowledged yesterday.

Ed Rybicki‘s insight:

"…clinical trials of vaccines made to protect against other viruses in the H7 family have shown the vaccines don’t induce much of an immune response, even when people are given what would be considered very large doses."

This is a little worrying – and possibly a spur to making universal vaccines!
