BASEL  Switzerland (AP) — Switzerland is going to the World Cup after left-back Ricardo Rodriguez denied Northern Ireland hope in both games of their playoff at either end of the field.
Switzerland needed only a draw Sunday to advance to Russia  and a tense 0-0 result in rain-soaked Basel was preserved by  Rodriguez 's goal-line clearance in stoppage time from Jonny Evans' header.
 Rodriguez  scored that spot kick on Thursday  when Corey Evans was whistled harshly for an incident that few agreed with.

"The conventional approach to developing flu vaccines today is one in which we perform surveillance worldwide " said David Topham  director of the New York Influenza Center of Excellence and professor of microbiology and immunology at the University of Rochester in New York.
"We collect the viruses that are circulating in people " said  Topham  who was not involved in the new study . Those viruses then typically are studied in ferrets    he  said.
"We create an antigenic map of each virus and determine how similar or different that is than the (current) vaccine strain  and if it's different enough from the vaccine strain then we select that virus to be in  next year's vaccine " Topham  said. In other words  they make their best guess on what strains will be most likely to spread and cause illness based on surveillance data
On the other hand  the new study suggests "using high-throughput sequencing methods and genetic engineering to rationally design a virus to use as a vaccine "  he  said. "I thought it was a very innovative and comprehensive approach."
The new study acted like "rocket science" compared with the conventional approach used to develop flu vaccines   he  said.
So what does the future hold for flu vaccines and where could this new approach fit in? There has been a shift among researchers around the world to focus on developing universal vaccines   Topham  said.
"These  for influenza  would be vaccines that would last for at least five years and protect against 75% of the viruses that are out there "  he  said. "There are many ways that we might be able to achieve that. This approach that's described in this paper is just one approach."

Former Vice President Joe Biden  said Tuesday that if  he  were one of President Donald Trump’s attorneys   he  would suggest Trump not consent to a special counsel interview for fear of being caught misleading investigators. “ The President  has some difficulty with precision ”  Biden  said in an interview with CNN’s Chris Cuomo.  Biden  said  he  marvels at some of the comments Trump makes and referenced a line from Trump on Monday that Democrats who did not applaud  his  State of the Union address were “un-American” and “treasonous.” The White House has since called the remark tongue-in-cheek  with press secretary Sarah Sanders saying on Tuesday that Trump was “clearly joking.” “Well let me tell you  he’s a joke ”  Biden  said in response.
I’m sorry to lose the main thread here  but I just have to take a moment to reflect on the state of affairs where Joe Freakin’ Biden is calling another politician a “joke.” That’s like Teddy Kennedy calling someone else a lecherous drunken criminal. Before Donald Trump  no American politician was a walking  talking punch line as often as  Joe Biden .  Biden ’s perpetually inappropriate comments and demeanor made for constant good fun  like the time  he  told a dude in a wheelchair to stand up:
Or the time that  he  extolled diversity in Delaware while talking to an Indian American by saying: “In Delaware  the largest growth in population is Indian Americans  moving from India. You cannot go to a 7-11 or a Dunkin’ Donuts unless you have a slight Indian accent. I’m not joking.”
All I’m saying is: maybe Joe Biden is kind of a joke too.
Ah  well. I’m sure Trump will figure out something. And I doubt  Biden ’s advice is going to figure into  his  decision much  one way or the other.
