Toronto, Nov 1, 2016: Vaccinating against dengue fever could increase outbreaks of Zika, warns a study by a team of researchers from Canada and China.
“Vaccinating against one virus could not only affect the control of another virus, it could in fact make it easier for the other to spread,” said one of the researchers Jianhong Wu, Professor at York University in Toronto, Canada.

The research, published in the journal Scientific Reports, identifies a potentially serious public health concern.
More than a third of the world’s population lives in areas where dengue is endemic and cases of co-infection with Zika have already been reported, according to the study.
“Recent evidence suggests that dengue virus antibodies can enhance the Zika virus infection. For that reason, we developed a new math model to investigate the effect of dengue vaccination on Zika outbreaks,” Wu said.

The team’s model showed that vaccinations for dengue increase the number of people contracting Zika.
It also showed that the more people in a particular population that are vaccinated against dengue, the earlier and larger the Zika outbreak.
The research also found that the most effective way to minimise the unintended effect of dengue vaccinations on Zika outbreaks is through an integrated strategy that includes mosquito control.
“We concluded that vaccination against dengue among humans can significantly boost Zika transmission among the population and hence call for further study on integrated control measures on controlling dengue and Zika outbreak,” Yanni Xiao, Professor at Xi’an Jiaotong University in China, said.

The researchers noted that their findings do not discourage the development and promotion of dengue vaccine products, however, more work needs to be done to understand how to optimise dengue vaccination programmes and minimise the risk of Zika outbreaks.
Although vaccines for dengue have been developed and are in use, there is currently no vaccine for Zika. (IANS)
"Do not click 'purchase' unless you are prepared to change everything about the way you sauce," the Heinz Packet Roller website says. The roller goes for $5.70. The roller is pocket-sized, can be added to a keychain, and features a packet corner cutter.
In April, Heinz pledged to increase production of ketchup by 25 per cent to 12 billion packets annually. "Gone are the days of fumbling with ketchup packets, pants ruined by mustard disasters, and minutes taken off your life trying to get to the bottom of that mayo packet. With the patent-pending Heinz Packet Roller, what was once taxing becomes simple -- just snip and roll to squeeze out every drop of your sauce of choice," the website says

Federer, who made a late decision to attend this year's Laver Cup in Boston -- a tournament held between teams from Europe and the rest of the world -- said on the sidelines of the event that the recovery and rehabilitation are "going to take me a few more months and then we'll see how things are at some point next year". "The reception I've received, everybody is so upbeat that I'm here. They wish me all the best and they don't even see the crutches. They just want me to be good again and enjoy the weekend," Federer said in an interview for the event with former world No. 1 Jim Courier.
"I've seen some incredible tennis, some great matches and it's been wonderful. I'm really happy I made the trip," the winner of 20 majors was quoted as saying by atptour.com. On why he opted for a third surgery, the tennis ace said, "I was just nowhere near where I wanted to be to play at the top, top level. But I tried my best and at the end... too much is too much. Now I've just got to take it step by step," Federer said.
Federer received thunderous ovations inside Boston's TD Garden, where he has often been sitting in the front row watching the action or behind the scenes visiting with the players. The former world No. 1 has played in the first three editions of the Laver Cup. "I think Boston is a great city. The stadium is wonderful, the crowds have been incredible. Both teams are stacked with absolute quality and top players," Federer said. "That's what the idea was behind it: that everybody could come together, have the most incredible weekend, learn from one another and then hopefully that's going to inspire them, motivate them and get them going for the rest of this year, next year."
