Verify if the sentiment of the following document towards the entity Schaffner is Negative . Dr. William Schaffner   medical director of the National Foundation for Infectious Disease  a nonprofit organization  told Business Insider that it's hard for experts for sure just how intense this flu season will be.
"Amongst ourselves  we say if you've seen one flu season  you've seen one flu season  " Schaffner  said.
Even so  there are a number of reasons why getting a flu shot is an especially good idea this year   Schaffner  said. Here's his five reasons for everyone who still hasn't gotten the vaccine this fall.
Australia  which heads into summer as the northern hemisphere goes into winter  got hit hard the flu this year. That's especially because of the H3N2 strain of the flu virus. While that still doesn't mean it will definitely be a bad flu season this year  the good news is that the particular strain is a good match to be protected against with  this year's vaccine Schaffner  said.
"I'm afraid we still hear that. No  you cannot get flu from the flu vaccine  " Schaffner  said. According to the CDC  flu shots are either made using an inactive virus that aren't infectious or a vaccine that doesn't contain the virus at all.
"We can do an awful lot of good with this pretty good vaccine  because it's the one we have to use today  " Schaffner  said.
There are plenty of ways to get vaccinated for free. Most insurers cover it as a preventive treatment  and Medicare covers the shot entirely. "It's easy  it's quick  it's covered by insurance  " Schaffner  said. Plus  most drugstore clinics  including Walgreens and CVS have the vaccines available  so you don't even have to go to a doctor's office.

Verify if the sentiment of the following document towards the entity Ted Cruz is Negative . Cruz 's fans say it 's because he stands on principle . 
In the three years since he arrived in the U.S. Senate , Ted Cruz has become easily the most hated man in Washington -- a fact he 's now using to his advantage as a presidential candidate . 
Is it true , as Cruz would have it , that the dreaded GOP establishment pays lip service to shrinking the federal government and repealing Obamacare , but actually would prefer to preserve the status quo ? 
Or do Cruz 's Beltway critics have a point ? 
Cruz has n't hesitated to take polarizing stances , even when doing so means taking on his Republican colleagues . 
Lee is also Cruz 's best friend -- maybe his only friend -- in the Senate . 
In his memoir , Cruz writes that no one stood by him "more courageously or indispensably" than Lee during his 21-hour anti-Obamacare speech that preceded the 2013 government shutdown . 
When Lee brought up his bill in the committee hearing , he was n't sure if he 'd have Cruz 's support . 
Cruz attacked the bill as dangerous and politically poisonous . 
Cruz went on to warn his fellow senators that if they voted for the bill , they would imperil their careers . 
Essentially , Cruz was saying that the legislation would let dangerous people out of prison , they would commit more crimes , and the senators would be subject to Willie Horton-style attack ads . 
Lee , who was sitting right next to Cruz , could not believe what he was hearing . 
Lee 's communications director , Conn Carroll , confirmed to me that Lee and his staff had no advance warning that Cruz was planning to brutally attack -- and , in Lee 's view , misrepresent -- his friend 's bill . 
The bill made it out of committee that day , but now it appears to be in trouble , with several other Republican senators taking Cruz 's line against it at a Senate lunch last week . 
Today , Lee has conspicuously joined every other sitting senator in declining to endorse Cruz 's presidential run . 
And while Lee and Cruz are still friends , the episode vividly illustrates Cruz 's talent for irritating other senators . 
Another telling episode came during the 2013 government shutdown , which Cruz spearheaded , insisting that if Congress defunded Obamacare , the president might go along . 
As McKay Coppins reports in his new book , The Wilderness , Cruz 's own staff never actually expected the gambit to work . 
To Cruz 's colleagues , it was a pointless and damaging exercise , but grassroots conservative groups cheered the effort . 
Cruz is close to the Fund and has appeared in its ads . 
At a private lunch of Republican senators , New Hampshire Senator Kelly Ayotte waved the document in Cruz 's face and demanded that he disavow it . 
When he declined , several other senators , including then-Minority Leader Mitch McConnell , took Ayotte 's side and denounced Cruz . 
In my conversations with Republican policy types and Senate aides about Cruz , this lack of regard for his colleagues , and for the niceties that have traditionally governed the upper chamber , was a common theme . 
As Trent Lott , the former Senate majority leader , told me last week , referring to the time Cruz called McConnell a liar on the Senate floor : "You just do n't do that . 
Another criticism of Cruz is that his antics are disruptive and damaging to the Republican Party . 
Cruz does have policy differences with the business wing of the party : Unlike the Chamber , he opposes comprehensive immigration reform , would like to kill the Export-Import Bank , and -LRB- in a reversal -RRB- opposed a recent free-trade bill . 
In Iowa , Cruz has been subjected to millions of dollars in attack ads and personally criticized by the Republican governor , Terry Branstad , for opposing ethanol subsidies . 
But a Republican policy expert close to a number of top GOP operatives and donors insisted it 's not about Cruz 's style or his positions . 
But the effort does n't result in smaller government or the end of Obamacare -- all it achieves is drawing attention to Cruz . 
You can see how these complaints look from the perspective of Cruz and his fans : like features , not bugs . 
But what about the criticism that Cruz 's efforts have n't gotten any results ? 
The Cruz camp did n't reply to my query , so I put the question to Amanda Carpenter , who was Cruz 's communications director during much of his time in the Senate , including the shutdown . 
Carpenter said Cruz had sent a message . 
Cruz has shown that one person can make a difference ." 
But as they see it , the difference Cruz has made in the Senate has not been a positive one .

Verify if the sentiment of the following document towards the entity Wang Yu is Positive . But on July 9 of that year   prominent Beijing rights lawyer Wang Yu  disappeared  along with  her  husband  also a lawyer  and their teenage son.
The following day  police raided  Wang 's law firm and detained seven of  her  colleagues. Seven other rights lawyers were also detained or reported missing  according to the Hong-Kong based China Human Rights Lawyers Concern Group  which has meticulously documented the cases. It became known as the "709 crackdown" -- a reference to the date the first arrests occurred.
 Sui  was among them.  He 'd earlier in the day spoken to two foreign media outlets to raise concern about  Wang 's disappearance.
That night  a security guard called up to Sui's apartment and said  his  car had been scratched in an accident and when  he  stepped outside  a group of police quickly whisked  him  away  said  Sui .  He  wasn't seen again for nearly five months.
Two days later  on July 12  the same thing happened to  Chen .  He  said police asked  him  to come down from  his  apartment to answer a few questions. "I intentionally left my cell phone upstairs in my apartment because I thought I'd be back in a few minutes."  He  didn't return for six weeks.
Dahlin says he was accused of masterminding a plan to smuggle the son of Wang Yu  the first lawyer to be detained in the swoop  into Myanmar  in an effort to evade authorities in October 2015.
After a month   Chen  said  he  was told to collect  his  belongings.  He  thought  he  was going home -- but instead was driven to what appeared to be an abandoned hotel and held for another 10 days.
Earlier this year  CNN visited the nondescript building where  Chen  said  he  was held in Guilin  a southern city famed for its stunning landscape of karst mountains. Signs posted around the area in Chinese and English marked it as military property  but it otherwise appeared open and accessible.
Sui says he admitted to charges of inciting subversion.  Chen  told CNN  he  confessed to charges of picking quarrels and provoking troubles  inciting subversion and embezzlement.
"You have to confess "  Chen  said. "Otherwise they won't let you go."
"Early on it was quite extreme. Every little noise at night would wake me up. I'd sleep with a knife next to my bed  ready to stab the first Chinese person who comes into my gate "  he  said.
 Wang Yu  poses during an interview in Hong Kong on March 20  2014.
 Wang Yu   the first lawyer detained in the 709 crackdown  was charged with subversion  while  her  husband was charged with inciting subversion. They were both released on bail after more than a year in custody  after  Wang 's taped confession was aired on CCTV.
In it   Wang  renounced  her  legal work and blamed "foreign forces" for using  her  law firm to undermine and discredit the government. Their son  who was detained along with them  was released soon afterward  but his movements have been heavily restricted.
Authorities never aired  Chen 's statement.  He  was released a day after recording it and the charges against  him  were dropped.
"I have no criminal record  but they can still use the video to discredit me "  he  said.
